VENUS

Venus's Moons and Rings

Unfortunately, Venus doesn’t have rings. It also doesn’t have any moons; although, Venus might have had a moon in the past, but it probably crashed back into the planet billions of years ago.

Venus's Period of Rotation

The rotation of Venus is clockwise, what astronomers call “retrograde”. Venus rotates backwards. Of course, since the length of a day on Venus is longer than a year, this rotation happens very slowly.

Why does Venus rotate backwards? One possibility is that Venus rotated normally when it first formed from the solar nebula, and then the tidal effects from its dense atmosphere might have slowed its rotation down.

Another theory is that a series of gigantic impacts early on in Venus’ history might have stopped or even reversed its rotation altogether. A similar impact happened to Earth billions of years ago, which formed the Moon.

Venus's Temperature

With a mean surface temperature of 735 K (462 °C; 863 °F), Venus is by far the hottest planet in the Solar System.

The Surface and The Interior

Venus is slightly smaller than the Earth, with a diameter 95% that of Earth (12,103 km) and a mass 81% that of Earth. If we could walk around on the surface of the planet (without being killed by the toxic blast furnace of an atmosphere), gravity would be close to that on the surface of Earth.

What is Venus's surface made of?

Shrouded by a thick atmosphere, the surface of Venus remained hidden until radar equipment arrived to probe the closest planet. Rocky ground lies beneath the layers of clouds. But unlike Mars and Mercury, which are both scarred by craters, Venus has a relatively smooth surface
