Spaceflight Simulator Wiki

The Sun is the body which all the planets in the solar system orbit. In-game, the Sun has five main bodies orbiting it, also known as planets. They are Mercury, Venus, Earth, Mars, and Jupiter.

When near the sun, there is an extremely bright light that makes the spacecraft difficult to identify.

The sphere of influence of the Sun is infinite, which indicates it is currently impossible to escape the Sun's gravitational influence. However, it is possible to exceed escape velocity, but bugs mentioned below may occur. But in real life, the sun's sphere of influence extends for 1 - 2 light years.

The Sun can be used for Mercury missions, due to the large Delta V needed to orbit Mercury.


The atmosphere is visible when zooming out from physics view. It extends up to 7 million kilometers. It is dense, like the Earth's atmosphere.

The sun's atmosphere can be used for aerobraking to slow down a spacecraft andor to decrease the aphelion of the spacecraft.


The sun has a gaseous surface, so rockets would sink down to the inner layers of the sun. Heat is still not added yet, so rockets would stay intact upon passing close to the sun's surface. The same behavior is shared by Jupiter.


  • If a spacecraft is more than 200 billion meters away from the Sun, it will freeze and occasionally be teleported to the center of the Sun.
  • It is possible to directly go into the Sun without any consequences other than visibility loss.
  • It is possible for a spacecraft to get stuck inside the Sun, but it is not common.
  • If your spacecraft accidentally crashes into it at extreme speeds (1 million+ m/s), the Sun may teleport it to nowhere, or the core of the Sun.


  • It is the only star in Spaceflight Simulator.
  • The sun can emit solar flares.
  • The bodies that orbit the sun are the 8 planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune), asteroids, comets, dwarf planets, space probes and all sorts of space debris, either natural or artificial.
  • The sun has orbiting sun probes.
  • The sun's atmosphere has the same density as the earth's atmosphere does. But in real life, it is much, much thinner.
  • The sun has a gaseous surface. It is located in the upper layers of the photosphere, or the sun's outer shell from which light is radiated.
  • The temperature of the sun is 5777 kelvin, but in the core, they reach into a sweltering 15 million kelvin.
