... In 1989 there was a space craft called Magellan orbiting Venus in order to map it’s surface. Venus is highly volcanic, lava forms solid waterfalls over much of it’s surface. The time it takes Venus to orbit the sun is 7.5 months to orbit the sun with no moons at all with no moons to follow it . ...

A Short History of Venus
... Venus underwent a runaway greenhouse effect – due to the presence of “greenhouse” gases. As the temperature increased, all of the existing water became vapor, circulated high into the atmosphere. This vapor was split apart by solar UV radiation, the hydrogen released was lost to the planet. Without ...

Venus
Venus is the second planet from the Sun, orbiting it every 224.7 Earth days. It has no natural satellite. It is named after the Roman goddess of love and beauty. After the Moon, it is the brightest natural object in the night sky, reaching an apparent magnitude of −4.6, bright enough to cast shadows. Because Venus is an inferior planet from Earth, it never appears to venture far from the Sun: its elongation reaches a maximum of 47.8°.Venus is a terrestrial planet and is sometimes called Earth's ""sister planet"" because of their similar size, mass, proximity to the Sun and bulk composition. It is radically different from Earth in other respects. It has the densest atmosphere of the four terrestrial planets, consisting of more than 96% carbon dioxide. The atmospheric pressure at the planet's surface is 92 times that of Earth's. With a mean surface temperature of 735 K (462 °C; 863 °F), Venus is by far the hottest planet in the Solar System, even though Mercury is closer to the Sun. Venus is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light. It may have had oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect. The water has most probably photodissociated, and, because of the lack of a planetary magnetic field, the free hydrogen has been swept into interplanetary space by the solar wind. Venus's surface is a dry desertscape interspersed with slab-like rocks and periodically refreshed by volcanism.
