Which planet revolves anticlockwise

For this reason, it is either referred to as the morning star or the evening star. Venus does not have any natural satellites. Venus and Earth are said to be sister planets because they are both terrestrial planets, their sizes are almost the same, and they are also close to one another. The term terrestrial planet implies that the surface of the planet is rocky, just like that of the earth.

There are also numerous traces that indicate that there have been a lot of volcanic activities in Venus. In fact, Venus has more volcanoes than earth. The atmosphere of Venus is very dense. It is composed of These oddities are thought to be caused by events, such as collisions, which occurred during the formation of the solar system. Jeff Mangum. Share this In , simulations suggested that a number of smaller collisions , rather than one big impact, knocked Uranus' spin to an angle of 98 degrees.

This could also explain why the planet's moons rotate at the same angle — something that would be unlikely if there were just one massive hit. An alternative explanation put forward by astronomers in is that Uranus once had a large moon, the gravitational pull of which caused the planet to fall on its side.

Eventually, the moon could have been knocked out of orbit by another planet, a bit like a game of cosmic pinball. As for Venus, our closest neighbour, scientists have suggested that it started off rotating counter-clockwise, then slowed down to be almost static, before starting to spin clockwise like it does now.
