Description
Venus is almost the same size as Earth, but the two worlds took very different paths. A dense carbon-dioxide atmosphere and a runaway greenhouse effect keep its surface hotter than Mercury's, with a pressure that would crush most spacecraft within hours. Thick clouds of sulfuric acid hide the ground, so its volcanic plains and highlands have been mapped mainly by radar. The planet turns very slowly and backwards compared with most others, so its day is longer than its year. Soviet Venera landers, including Venera 13 with its colour panoramas, sent back the only pictures from the surface, while many probes such as Mariner 10, Galileo, Cassini, MESSENGER, Parker Solar Probe and BepiColombo studied it during flybys.
