Which planet rotates in the opposite direction. Ten interesting facts about Venus. The atmosphere of Venus is extremely hostile

Planet Venus interesting facts. Some you may already know, others should be completely new to you. So read and learn new interesting facts about the "morning star".

Earth and Venus are very similar in size and mass, and they orbit the Sun in very similar orbits. Its size is only 650 km smaller than the size of the Earth, and the mass is 81.5% of the mass of the Earth.

But that's where the similarity ends. The atmosphere consists of 96.5% carbon dioxide, and the greenhouse effect raises the temperature to 461 °C.

2. A planet can be so bright that it casts shadows.

Only the Sun and Moon are brighter than Venus. Its brightness can vary from -3.8 to -4.6 magnitudes, but it is always brighter than the brightest stars in the sky.

3. Hostile atmosphere

The mass of the atmosphere is 93 times greater than the Earth's atmosphere. The pressure on the surface is 92 times greater than the pressure on Earth. It is also like diving a kilometer under the surface of the ocean.

4. It rotates in the opposite direction compared to other planets.

Venus rotates very slowly, a day is 243 Earth days. Even stranger is that it rotates in the opposite direction compared to all other planets in the solar system. All planets rotate in a counter-clockwise direction. Except for the heroine of our article. It rotates clockwise.

5. Many spacecraft have managed to land on its surface.

In the midst of the space race Soviet Union launched a series of Venus spacecraft and some have successfully landed on its surface.

Venera 8 was the first spacecraft to land on the surface and transmit photographs to Earth.

6. People used to think that there are "tropics" on the second planet from the Sun.

While we sent the first spacecraft to study Venus at close range, no one really knew what was hidden below under the dense clouds of the planet. Science fiction writers dreamed of lush tropical jungles. The hellish temperature and dense atmosphere surprised everyone.

7. The planet has no satellites.

Venus looks like our twin. Unlike Earth, it has no moons. Mars has moons, and even Pluto has moons. But she... no.

8. The planet has phases.

Although it looks like a very bright star in the sky, if you can look at it with a telescope, you will see something different. When looking at it through a telescope, you can see that the planet goes through phases like the moon. When it is closer, it looks like a thin crescent. And at the maximum distance from the Earth, it becomes dim and in the form of a circle.

9. There are very few craters on its surface.

While the surfaces of Mercury, Mars, and the Moon are littered with impact craters, there are relatively few craters on the surface of Venus. Planetary scientists believe that its surface is only 500 million years old. Constant volcanic activity smoothes and removes any impact craters.

10. The last ship to explore Venus is the Venus Express.

Is it true that Venus rotates counterclockwise? and got the best answer

Answer from Ulenspiegel[guru]
Yes it's true. And Uranus generally lies "on its side."

Answer from Glukhov Ivan[newbie]
Venus rotates in the opposite direction to its orbit. That is, the sun rises in the west and sets in the east.

Answer from Ivan Vasilievich changes profession[guru]
She spins venereal, of course!

Answer from Dmitry Nizyaev[guru]
Depending on which pole you're watching from... But no matter how it spins, it's not at all surprising. And why shouldn't she, in fact, rotate at least like that, at least that way? Uranus is really amazing. It rotates completely out of the plane of its orbit, and this is a very unstable position. Strictly speaking, in the process of its formation, the planet has a chance to acquire the resulting rotation in absolutely any plane and in any direction. But if the plane of rotation of the planet does not coincide with the plane of its orbit, then tidal forces cause precession - about the same behavior as a spinning top, whose axis is not vertical. Friction forces arise along the Coriolis arcs, and these forces gradually, turn by turn, change the direction of the axis of rotation. And the closer the plane of rotation is to the plane of the orbit, the less the Corisolis forces interfere in the process - which sooner or later leads to the balancing of this plane. Therefore, most planets rotate exactly or almost exactly in the plane of their orbit.
And Uranus - rotates across! And from this one can draw one of two conclusions: either Uranus is much younger than the rest of the planets in the system, or the plane of its rotation accidentally turned out to be so close to the perpendicular to the orbit that the Coriolis forces balance each other. Figuratively speaking, the planet was in such perfect balance that it still cannot decide which side it should fall on. A rare case, it turns out!

Answer from Nikolai Gorelov[guru]
Look at the sky. The sun scratches it clockwise, which means our Earth is against the clock. Then, Venus spins clockwise, that is, not like people do.

Answer from 3 answers[guru]

Hello! Here is a selection of topics with answers to your question: Is it true that venus spins counterclockwise???

I became interested in the topic of what rotates clockwise and what against. Very often you can find a lot of things in the world based on vortexes, spirals, twists, having a right spin of rotation, that is, twisted according to the gimlet rule, the right hand rule, and the left spin of rotation.

Spin is the intrinsic angular momentum of a particle. In order not to complicate the note with theory, it is better to see once. The element of the slow waltz is the right spin turn.

For many years there has been a discussion among astronomers about the direction in which spiral galaxies rotate. Do they rotate, dragging spiral branches behind them, i.e., twisting? Or do they rotate the ends of the spiral branches forward, unwinding?

At present, however, it is becoming clear that observations confirm the hypothesis of TWISTING of the spiral arms as they rotate. American physicist Michael Longo managed to confirm that most of the galaxies in the Universe are oriented to the right (right spin of rotation), i.e. rotates clockwise when viewed from its side north pole.

Rotation solar system occurs counterclockwise: all planets, asteroids, comets rotate in the same direction (counterclockwise, as viewed from the north pole of the world). The sun rotates on its axis counterclockwise when viewed from the north ecliptic pole. And the Earth (like all the planets of the solar system, except for Venus and Uranus) rotates counterclockwise around its axis.

The mass of Uranus, sandwiched between the mass of Saturn and the mass of Neptune, under the influence of the rotational moment of the mass of Saturn, received a clockwise rotation. Such an impact from Saturn could occur for the reason that the mass of Saturn is 5.5 times the mass of Neptune.

Venus rotates in the opposite direction than almost all planets. The mass of the planet Earth spun the mass of the planet Venus, which received a clockwise rotation. Therefore, the daily periods of rotation of the planets of the Earth and Venus should also be close to each other.

What else is spinning and spinning?

The snail's house spins clockwise from the center (i.e., the rotation here is with a left spin turn, counterclockwise).

Tornadoes, hurricanes (winds centered in the cyclone area) blow counterclockwise in the Northern Hemisphere and are subject to centripetal force, while winds centered in the anticyclone area blow clockwise and have centrifugal force. (In the Southern Hemisphere, it's exactly the opposite.)

The DNA molecule is twisted into a right-handed double helix. This is because the backbone of the DNA double helix is made up entirely of right-handed deoxyribose sugar molecules. Interestingly, when cloning, some nucleic acids change the direction of twist of their spirals from right to left. On the contrary, all amino acids are twisted counterclockwise, to the left.

Flocks of bats, flying out of the caves, usually form a "right-handed" vortex. But in the caves near Karlovy Vary (Czech Republic), for some reason they circle in a counterclockwise spiral...

In one cat, at the sight of sparrows (these are her favorite birds), the tail rotates clockwise, and if these are not sparrows, but other birds, then it rotates counterclockwise.

And if we take Humanity, then we see that all sporting events (car races, horse races, running at the stadium, etc.) pass counterclockwise. After some centuries, athletes noticed that it is much more convenient to run this way. Running the stadium counterclockwise, the athlete takes a wider step with his right foot than he would have taken with his left, since the range of motion of the right leg is several centimeters larger. In most armies of the countries of the world, the turn around is carried out through the left shoulder, that is, counterclockwise; church rituals; the movement of cars on the roads in most countries of the world, with the exception of the UK, Japan and some others; at school, the letters "o", "a", "c", etc. - from the first grade they are taught to write counterclockwise. In the future, the vast majority of the adult population draws a circle, stirs the sugar in the mug with a spoon counterclockwise.

And what follows from all this? Question: Is it natural for a person to rotate counterclockwise?

As a conclusion: the Universe moves clockwise, but the solar system is against it, the physical development of all living things is clockwise, consciousness is against it.

Venus is the brightest object in the sky. Although ancient people knew about Venus, some cultures believed that she was two separate celestial objects - the evening star and the morning star. The Greek astronomer was the first to realize that the evening and morning stars are actually one object. Many cultures have attributed to the planet a corresponding goddess of love and beauty. Venus is the Roman name for this goddess. The Babylonians called the planet Ishtar, while the Greeks called it Aphrodite.

The average distance from Venus to the Sun is 108.21 million kilometers. This is an average distance, since Venus moves in an elliptical orbit around the Sun. At its closest point in its orbit, called perihelion, Venus is only 107.48 million kilometers from the Sun. And then at the farthest point of its orbit, Venus is 108.94 million kilometers from the Sun.

Venus takes 224.7 days to complete one orbit around the sun. But it also takes 243.02 days to turn around on its axis. In other words, a day on Venus is actually longer than a year on Venus. It is also strange that Venus rotates in the opposite direction compared to. Seen above the north pole, Venus is seen turning clockwise. If you could stand on the surface of Venus, you would see the Sun rise in the west as it slowly moves across the sky and set in the east, unlike the Earth.

Scientists believe that Venus is a twin because of its similarity. For example, the radius of Venus is 6.052 km; 95% of the Earth's radius. The mass of Venus is 81.5% of the mass of the Earth, and the density is 5.24 g/cm 3 , while the density of the Earth is 5.51 g/cm 3 . If you were standing on the surface of Venus, you would experience 90% of the gravity you feel on Earth.

A day on Venus lasts 243 days; which is unusual considering the fact that a year on Venus is only 224.7 days long. In other words, a day on Venus is longer than its year. Moreover, Venus is the only planet in the solar system that rotates clockwise around its axis. All other planets rotate counterclockwise.

Radar imaging of the surface of Venus has shown it to have impact craters all over the planet and evidence of widespread volcanism. smaller and almost always low shield volcanoes. Some big event was thought to have reshaped the surface of Venus 300-500 million years ago, erasing older impact craters and volcanoes. This event also turned off the planet's plate tectonics, trapping heat inside the planet. Without heat escaping, convection in Venus's core also stopped and the planet lost its magnetic field. The interior of Venus is similar to the Earth. The planet has a core of metal, surrounded by a mantle of stone, and a thin crust. But unlike Earth, Venus has no plate tectonics and no carbon cycle that moves carbon out of the atmosphere and stores it inside the planet. This is one of the problems that may have led to Venus's runaway greenhouse effect.

While Venus has many similarities to Earth, it also has many differences. Perhaps the biggest difference is in its atmosphere. The atmospheric pressure on the surface of Venus is 92 times greater than at sea level. In fact, you would have to dive to a depth of 1 km below the surface of the ocean to experience the same pressure. This atmosphere is composed almost entirely of carbon dioxide, with dense clouds of sulfur dioxide. Due to the atmosphere of carbon dioxide, Venus experiences the strongest in the solar system. The temperature on the surface of Venus is 460°C, no matter where you are on the planet. It's hot enough to melt lead, and it destroyed the spacecraft in a matter of hours.

At one time, scientists and science fiction writers believed that the surface of Venus was tropical in nature. Some believe that faith was the only reason the Soviet Union launched a series of surface probes to the planet. After seven missions were destroyed under pressure before they could reach the surface, Venera 8 landed and disappointed millions. Several other probes were able to land in the following years. The last one to land was the Venus Express. He arrived in April 2006 and studied the planet's surface and atmosphere until he could no longer work.

Because of its dense clouds, Venus could not be observed from Earth. Early observations showed that the planet went through phases just like the Moon, demonstrating that it orbits the Sun inside the Earth's orbit. But until the first spacecraft observations were made, astronomers did not fully understand what was underneath the dense clouds. Radar photos from NASA's Magellan spacecraft imaged the entire planet, revealing a hellish world covered in rocks and ancient lava flows. Several Russian spaceships landed on the planet's surface after only a few hours and sent photos from the planet's surface.

Venus is often referred to as the Morning Star because it orbits closer to the Sun than our planet. This causes Venus to appear in the western sky after sunset and before sunrise in the eastern sky. In addition, only the Sun and Moon are brighter than Venus in our night sky. Because of all this, Venus is hard to ignore, even with the naked eye.

Venus has no moons or rings.

The title of the article you read "Venus".

Venus is the second planet of the solar system. Its neighbors are Mercury and Earth. The planet was named after the Roman goddess of love and beauty - Venus. However, it soon turned out that the surface of the planet had nothing to do with the beautiful.

Knowledge about this celestial body was very scarce until the middle of the 20th century due to dense clouds hiding Venus from the view of telescopes. However, with the development of technical capabilities, mankind has learned many new and interesting facts about this amazing planet. Many of them raised a number of questions that are still unanswered.

Today we will discuss the hypotheses that explain why Venus rotates counterclockwise, and we will tell interesting facts about it, known to planetology today.

What do we know about Venus?

In the 60s, scientists still had a glimmer of hope that the conditions for living organisms. These hopes and ideas were embodied in their works by science fiction writers who described the planet as a tropical paradise.

However, after the spacecraft were sent to the planet, which provided the first idea about the scientists, they came to disappointing conclusions.

Venus is not only uninhabitable, it has a very corrosive atmosphere that destroyed several of the first spacecraft sent into its orbit. But despite the fact that the connection with them was lost, the researchers still managed to get an idea about chemical composition atmosphere of the planet and its surface.

Also, researchers were interested in the question of why Venus rotates counterclockwise, just like Uranus.

twin planet

Today it is known that Venus and the Earth are very similar in physical characteristics. Both of them belong to the terrestrial group of planets, like Mars and Mercury. These four planets have few or no moons, weak magnetic fields, and no ring systems.

Venus and the Earth have a similar mass and are only slightly inferior to our Earth), and also rotate in similar orbits. However, this is where the similarity ends. The rest of the planet is in no way similar to Earth.

The atmosphere on Venus is very aggressive and consists of 95% carbon dioxide. The temperature of the planet is absolutely unsuitable for life, as it reaches 475 ° C. In addition, the planet has very high pressure (92 times higher than on Earth), which will crush a person if he suddenly decides to walk on its surface. Destroy all living things and clouds of sulfur dioxide, creating precipitation from sulfuric acid. The layer of these clouds reaches 20 km. Despite its poetic name, the planet is a hellish place.

What is the rotational speed of Venus on its axis? As it turned out as a result of research, one Venusian day is equal to 243 Earth days. The planet rotates at a speed of only 6.5 km / h (for comparison, the rotation speed of our Earth is 1670 km / h). At the same time, one Venusian year is 224 Earth days.

Why does Venus rotate counterclockwise?

This question has been troubling scientists for more than a decade. However, no one has been able to answer it so far. There have been many hypotheses, but none of them has yet been confirmed. Nevertheless, we will consider some of the most popular and interesting ones.

The fact is that if you look at the planets of the solar system from above, Venus rotates counterclockwise, while all other celestial bodies (except Uranus) rotate clockwise. These include not only planets, but also asteroids and comets.

When viewed from the north pole, Uranus and Venus rotate clockwise, and all other celestial bodies - against it.

Reasons why Venus rotates counterclockwise

However, what caused this deviation from the norm? Why does Venus rotate counterclockwise? There are several popular hypotheses.

Once upon a time, at the dawn of the formation of our solar system, there were no planets around the Sun. There was only one disk of gas and dust, which rotated clockwise, which over time was transferred to other planets. A similar rotation was observed for Venus. However, soon the planet likely collided with a huge body that crashed into it against its rotation. Thus, the space object seemed to "launch" the movement of Venus in the opposite direction. Maybe Mercury is to blame. This is one of the most interesting theories which explains several amazing facts. Mercury was once a satellite of Venus. However, later he collided with her on a tangent, giving Venus part of his mass. He himself flew into a lower orbit around the Sun. That is why its orbit has a curved line, and Venus rotates in the opposite direction.
Venus can be rotated by the atmosphere. The width of its layer reaches 20 km. Moreover, its mass is slightly less than the earth. The density of the atmosphere of Venus is very high and literally squeezes the planet. Perhaps it is the dense atmosphere that rotates the planet in a different direction, which explains why it rotates so slowly - only 6.5 km / h.
Other scientists, observing how Venus rotates around its axis, have come to the conclusion that the planet is turned upside down. It continues to move in the same direction as the other planets, however, due to its position, it rotates in the opposite direction. Scientists believe that this phenomenon could be caused by the influence of the Sun, which caused strong gravitational tides, combined with friction between the mantle and the core of Venus itself.

Conclusion

Venus is a terrestrial planet, unique in nature. The reason why it rotates in the opposite direction is still a mystery to mankind. Maybe someday we'll figure it out. In the meantime, we can only build assumptions and hypotheses.
