Venus is the second planet from its sun, orbiting it every 224.7 Earth days. It has the longest rotation period (243 days) of any planet in Sol and rotates in the opposite direction to most other planets. It has no natural satellite. It is named after the Roman goddess of love and beauty. It is the second-brightest natural object in the Earth night sky after Luna, reaching an apparent magnitude of −4.6, bright enough to cast shadows. Because Venus orbits within Earth's orbit it is an inferior planet and never appears to venture far from its sun; its maximum angular distance from it (elongation) is 47.8°.

Although attempts have been made to construct some sort of a settlement on Venus, whether it be a mining facility or research center, conditions on the planet have time and time again proven to be too extreme. As a result, an orbital space station was built to study the planet.
