This impact obliterated much of the ancient Earth and Thea, whose parts reformed into both our home planet and the Moon. It's theorised that these two odd-balls got their strange spin after being hit by something else during the Solar System's formational period.Īs a side note, it's also hypothesized that Earth was hit by another planet, which scientists have called Thea, 4.5 billion years ago. A day on Venus is equivalent to 116 days on Earth. Join ResearchGate to ask questions, get input, and advance your work. Uranus rotates about its axis that is nearly parallel with its orbital plane, meaning it's on its side, whereas Venus actually spins counter-clockwise and has the slowest rotation of all the planets. Why do Mercury, Venus, Earth, Mars, Jupiter, Saturn, and Neptune spin counterclockwise.
Of the larger objects with enough gravity to pull themselves into a sphere and mass to be considered a planet, there are two outliers: Earth's evil twin Venus and the gas giant Neptune. The clump of primordial dust and gas that eventually became the Solar System is theorised to have spun counter-clockwise, and as the various bits of it condensed into the Sun, planets and everything else it kept this direction in both their spin and in the case of everything that is not the Sun, its orbit. This is due to the initial conditions in the clouds of gas and dust in which our Solar System formed. The Sun spins counter-clockwise on its axis along with most of the objects in the Solar System. Another planet colliding with Venus at just the right angle could have reversed its rotation.THE Sun and all the planets in the solar system spin counter-clockwise. A collision between Venus and another planet could explain why Venus rotates counterclockwise. Every planet in our solar system except for Venus and Uranus rotates counter-clockwise as seen from above the North Pole that is to say, from west to east. Venus was no exception, and it likely experienced at least one major collision with another planet. Collisions between entire planets were commonplace, and every planet in the solar system is believed to have undergone one or more crashes in the past. The gravitational pull of the forming planets tugged on one another and brought each other closer together. One of the most long-standing hypotheses is that Venus and Uranus originally rotated counter-clockwise like Earth and the other planets still do but were struck at some point by massive objects (perhaps other planets) that sent them spinning in different directions.
The early solar system was chaotic, and none of the current planets had found themselves in a stable orbit. There were likely as many as a hundred planets forming in the early solar system. Which way does Venus spin All the planets in the Solar System orbit the Sun in an anticlockwise direction as viewed from above Earths north pole. The other planets rotate in a counterclockwise direction. In fact, there are two planets that spin on their axes from east to west. Venus, Uranus, and the dwarf planet Pluto all spin in a clockwise direction as seen looking down on their north poles. Uranus was likely hit by a very large planetoid early in its history, causing it to. This is the same direction in which all the planets orbit the sun. What dictates the direction of rotation A. Every planet in our solar system except for Venus and Uranus rotates counter-clockwise as seen from above the North Pole that is to say, from west to east. Although the solar system has eight planets today, that has not always been the case. Which is the only planet rotating clockwise I read that Venus is the only planet to rotate clockwise. Shortly after the sun was born, the planets began to form as well. Instead, something must have caused Venus to start spinning the other way. It simply would not have been possible for Venus to rotate clockwise after its formation, given the rotation of the protoplanetary disk it formed in. Planetary Collision Two Planets Colliding into One AnotherĪfter it formed, Venus likely rotated counterclockwise like all the other planets.
