Venus is the second planet from the Sun. It is currently the closest planet to Earth and it is well known for its thick atmosphere and hot surface. Venus, like Mercury, has no moons.

Venus shares the same charateristics as Earth, since their size, mass and gravity are almost similar to Earth.

Venus has an atmosphere that is, very thick. Landing on it is easy, and it is only required for rockets to use retrorockets to slow down. Heavy rockets might use some parachutes to slow down the rocket. Venus's atmosphere is thick, so returning from the surface is hard, due to the atmosphere slowing down any rocket passing through.

Venus has terrain that is, very rough. The rough terrain is the cause of rockets tipping over after landing.

Venus has a large gravity, and a large sphere of influence, so it is easier to go to orbit to Venus using fuel than it is to go to orbit on Mars or Mercury. However, circularization burns are a hard task to do on Venus, because of its size.

Venus is the cheapest planet to get to in the Solar System. Coupled with its high mass, it is well suited for Gravity Assists.

A player wishing to set up a colony on the surface of Venus may want to make a Space Station or fuel depot so that rockets can land and return to Earth easily.

Venus's large sphere of influence, gravity and mass is enough for rockets to easily get to orbit on. A rocket can go to orbit using less fuel when going the old-fashioned way to get to orbit. A player can also use aerocapture, but it is risky, since its atmosphere is thick.

Venus’s Atmosphere

Venusian atmosphere

Venus has a thick, yellow atmosphere that extends up to 40 kilometers above the surface. It has clouds that extend up to around 3 kilometers in the air.

Since it is 4.8 times as dense as Earth’s, it is very useful for aerobraking and making descents with parachutes.

The high pressure of the atmosphere also makes it very difficult to return to orbit. When making a spacecraft to return from the surface, make sure that it is as aerodynamic and thrust-worthy as possible.

You can do gravity assists on Venus for a Mercury mission, because it is the easiest way to go to Mercury. You can also use to orbit on Venus to go to Mercury.

Venus’s Surface

See also: Venus Landing Mission

Venusian surface

Venus’s surface is covered in large volcanoes and mountains that can extend many meters (or sometimes, kilometers) into the air. Although it may be difficult, landing on top of one of the volcanoes/mountains may be useful for returning to orbit, since the atmosphere is thinner.

If you zoom out in physics view on Venus, the color would change from dark yellow to light yellow.

Since the terrain is often uneven, surface bases may not work very well, but rovers, landers and atmospheric probes that landed there can operate just fine.

An interesting fact about Venus's terrain is it changes color when you zoom out in physics view.


Special Orbits

  • Synchronous Orbit: 3,242.43 km


  • Venus is one of the hardest planets to return from. Doing so may get you recognized as a good player.
  • Venus may have had been habitable once. But, 700 million years ago, a runaway greenhouse effect happened, causing its atmosphere to thicken.
  • Venus might also had a moon once, which is also habitable. But, a planet from space collided with Venus, causing its retrograde rotation and its moon collided back with Venus.
  • Venus is named after the Roman goddess of love and beauty.
  • The sun rises in the west and sets in the east on Venus. This is also called retrograde motion.
  • In real life, Venus's atmosphere is 93× as dense as Earth's, like 930 meters below sea level.
  • Venus is also called as the sister of Earth, since Venus shares the same charateristics as Earth.
  • Venus has very high pressure, which make atmosphere is completely opaque and surface is doesn't visible
