Venus is almost Earth’s twin in size and mass, but its thick carbon dioxide atmosphere creates a runaway greenhouse effect. The surface pressure is about 92 times Earth’s and the mean temperature about 464 °C, hotter than Mercury.

It rotates backwards (retrograde) and very slowly: one rotation takes 243 Earth days, longer than its 225-day year. Seen from Earth it is the brightest object in the night sky after the Moon.
