Planets Expansion Required
Some or all of the features on this page requires the Planets Expansion in-app purchase.


Jupiter is the largest planet in the Solar System. It was added in the 1.4 update, but is only available if the Planet Expansion DLC has been purchased.

The planet has 4 moons: Io, Europa, Ganymede, and Callisto. But in real life, it has 80 moons.

The planet's thick atmosphere is well suited for aerobraking and using aerocapture. Use of this tactic was impossible before 1.5, as due to a bug, there was an issue where a vessel's velocity caps out at 10,000 m/s in an atmosphere, meaning that attempting to aerobrake at Jupiter would cause a ship's orbit to suddenly reduce to almost sub-orbital speeds.

While it appears to have a surface, you cannot land on Jupiter. In Jupiter’s code, terrain collision has been edited in such a way that you cannot in any way touch it, similar to the Sun.

To get into orbit around Jupiter's moons, either rendezvous (so your trajectories intersect, see Rendezvous and Docking Tutorial and Trajectory Correction Maneuvers), or match their orbit as closely as possible (Hohmann transferring).

Atmosphere

The atmosphere is in an orange hue. The atmosphere is 5 times as thick as Earth, thicker than Venus, but in real life the pressure is at 1000× as thick as Earth's. Rockets that enter the lower layers of the atmosphere would spin uncontrollably, and would slow down so much that parachutes, when deployed would then become destroyed, along with the spacecraft.

In real life, the pressure is so intense that the Galileo space probe got crushed at the pressure of about 25 bar, or 25 times the atmospheric pressure of Earth.

Terrain

Jupiter has a liquid surface. So, expect for the terrain to change.

Information

Jovistationary orbit: 577,656 m

Around Jupiter

Jupiter has huge gravity. It has a large sphere of influence and many moons. It can be used for:

Gravity Assists

Jupiter gravity assists are used to a spacecraft when they reach far away objects (such as another planet, a Kuiper belt object or even the far reaches of the solar system).

Grand Tour of the Solar System

Doing so would recreate the Voyager probes' missions. But, you must wait for planetary alignments to conduct this mission.

Exploring all planets of the solar system

This is very complex. You must do it with a planet pack with objects past Jupiter. You must also assemble rocket stages that orbit planets. Doing this would cost large amounts of fuel and this would take a lot of time.

Continuation

You could build a Jupiter space station, but due to the size of Jupiter, orbits are hard to align. You can also do it in Jupiter's moons, since they are smaller.

A Jupiter return mission could be done, but it would take a lot of time and fuel.

There are so many things to do in Jupiter, other than that.

Trivia

  • Jupiter is massive enough to have a major influence on the barycenter of the Solar System, but SFS’ physics engine does not support this.
  • Jupiter's atmosphere is the densest of any celestial object (0.025 (5 Earth's)), slightly denser than Venus' (0.024 (4.8 Earth's)) and much denser the Sun's (0.005 (Same as Earth)).
  • 0.005 density of atmosphere is equal to 1 bar or even 1 atmosphere of Earth.
  • Gas Giants in the solar system have a pressure of 1000 atmospheres of earth, not suitable for parachutes. Use ion engine burns for slowdown.
  • The intense pressure of the gas giants will crush the spacecraft completely.
  • Jupiter is sometimes called a "failed star" due to not being massive enough to have internal pressure and temperature to cause hydrogen and helium to be fused.
