Venus
is very similar to Earth. The two planets have about the same size
and mass. But Venus does not look blue, as Earth does. Venus has no
ocean. It is covered with a thick mass of clouds. The clouds spin
very fast, trapping surface heat. This makes the surface
temperatures very hot and the surface pressure very high.
Venus revolves around the sun once every 225 (Earth) days. It takes
243 Earth days for it to make one rotation on its axis. Venus spins
in the opposite direction, compared to Earth. If you lived on Venus,
the sun would appear to rise in the west and set in the east!
The surface of Venus is
highly eroded. It also has large volcanic ridges. It has an iron
core that is about 3000 kilometers in diameter. Scientists think
this core might be liquid and extends halfway to the surface of
Venus.
