Venus is the second planet from the Sun. Venus is classified as a terrestrial planet and it is sometimes called Earth’s “sister planet” due to the similar size, gravity, and bulk composition.
Venus is covered with an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light. Venus has the densest atmosphere of all the terrestrial planets in our solar system, consisting mostly of carbon dioxide.
A younger Venus is believed to have possessed Earth-like oceans, but these evaporated as the temperature rose. Venus’s surface is a dusty dry desertscape with many slab-like rocks, periodically refreshed by vulcanism. (From Wikipedia)
