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

Callisto is the second-largest and most distant of Jupiter’s Galilean moons. It is colorful and spotty in appearance. Callisto is included in the Planets Expansion DLC.

Landing on Callisto is relatively easy because it is far away from Jupiter. Callisto's gravity is the smallest of all the Galilean moons at 1.235 m/s2. Callisto's terrain is usually smooth with some big and wide craters.

What to do on Callisto

Callisto, similar in more ways than one to Ganymede, is prime for gravity assists. Low passes can be hazardous as the rims of Callisto’s craters can exceed 200 meters in height.

However, easy orbits around Callisto can be achieved without gravity assists, because at Callisto’s distance from Jupiter, your rocket will not be moving at a very high velocity, even if it is on an escape trajectory.

Terrain

Like the Moon or Mercury, Callisto’s surface is heavily cratered. Unlike the moon, however, these craters are remarkably large and have some rough surfaces on them. The flat surfaces are usually have small hills with a few shallow craters. Callisto's craters are not that steep as the Moon's or Mercury's craters are.

Make sure your rocket has a wide base so it does not tip if you land at an odd angle and land on a flat surface to avoid tipping.

Trivia

  • Callisto, like Io, was not included in any 1.4 game peeks.
  • Callisto is far from the most distant moon of Jupiter. That title is held by Sinope.
  • Callisto is one of the most cratered bodies in the Solar System.
  • Some of the crater plains on Callisto could be as old as the Earth.
  • Like the rest of the Galilean moons, Callisto was a lover of Zeus. Hera, enraged by her husband’s affair with Callisto, turned her into a bear. Right before she was going to be killed, she was turned into the constellation Ursa Major.
  • In the game, Callisto is the same size as Mercury, sharing a radius of 120 kilometers; but in reality, Callisto is slightly smaller than Mercury.
  • Callisto could possibly have high mountain peaks because of impacts on the surface that create shockwaves.
