'''Venus''' is the second planet from the [[Sun]]. It has a day longer than a year. The year length of Venus is 225 [[Earth]] days. The day length of Venus is 243 Earth days. It is a terrestrial planet because it has a solid, rocky surface like other planets in the inner solar system. Astronomers have known Venus for thousands of years. The ancient Romans named it after their goddess Venus. Venus is the brightest thing in the night sky except for the [[Moon]]. It is sometimes called the morning star or the evening star as at some elongations it is easily seen just before the sun comes up in the morning and, at other elongations, just after the sun goes down in the evening. Venus comes closer to the Earth than any other planet does.

Venus is sometimes called the sister planet of [[Earth]] as they are quite similar in size and gravity. In other ways, the planets are very different. Venus' atmosphere (air) is mostly carbon dioxide with clouds of sulphuric acid. Sulphuric acid is a chemical that is very poisonous to humans.

The thick atmosphere has made it hard to see the surface, and until the twenty-first century, many people thought things might live there. The pressure on Venus' surface is 92 times that of Earth. Venus has no moons. Venus spins very slowly on its axis and it spins in the opposite direction to the other planets.

== Surface features ==
Although Venus is modeled as a sphere, there are more than 2000 surface features marked on Venus and are labeled if the labels are turned on in the Display menu.

== Historical missions to Venus ==
For a complete list of historical missions, see ''[[Missions to Venus]]''.

== Flight Warning! ==

At the surface of '''Venus''', the atmospheric pressure is 9.2MPa, over 90 atmospheres. This is substantially greater than the back-pressure which standard rocket motors are able to generate; a [[Delta-glider]] landed on Venus will not be able to take off (at least if the [[complex flight model]] is in use).
