Spaceflight Simulator Wiki

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

The Sun is an energy source for spacecraft using solar panels. The energy from the sun is absorbed by the solar panel, which generates power for the spacecraft.

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. It is possible to reach escape velocity, but bugs mentioned below may occur.


A rocket close to the sun

The Sun's atmosphere, or corona, is visible when zooming out from physics view, even when you're far away from it. It extends up to around 800,000 kilometers; the "true" atmosphere starts at 300 km above the surface. It is dense like the Earth's atmosphere.

Getting too close to the sun can make the rocket melt in a fraction of a second, as shown to the picture on the left.

The Sun has 5 bodies orbiting it, called Mercury, Venus, Earth, Mars and Jupiter. But in real life, the Sun also has asteroids, meteoroids, comets and space probes orbiting it.

Jupiter is the largest, while Mercury is the smallest. Earth, Mars and Jupiter have moons, while Venus, Earth, Mars, Jupiter and Europa have atmospheres of their own.


The sun has a gaseous surface, so rockets would sink down to the inner layers of the sun (if you somehow found a way to land on the sun without melting). When you try to touch the sun (even the outer layers of its corona), the rocket will, and certainly will melt. The same behavior is shared by Jupiter.


  • If a spacecraft travels more than 1.78E+310 meters away from the Sun, you will hit an invisible wall that pushes your rocket back every frame. If the rocket is travelling fast enough to get past that wall the game crashes.
  • It is possible for a spacecraft to get stuck inside the Sun, but it is not common.
  • If your spacecraft flies into it at extreme speeds, it may teleport to nowhere, or the core of the Sun.


  • It is the only star in Spaceflight Simulator.
  • The Sun can be commonly called as Sol.
  • 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's surface is 5777 kelvin; but in the core, they reach into a sweltering 15 million kelvin.
  • Light from the sun cannot reach an object beyond 1200 astronomical units.
