Solar System Planets

The largest and earliest formed planet in the Solar System, contains over twice as much material as the rest of the solar system combined. Influenced the formation of the other bodies in the solar system greatly. Second brightest planet in the sky and named after the king of the gods. Has four large moons and dozens of smaller ones. Upper atmosphere composed of liquid hydrogen and helium, may have a small rocky core and no solid surface. Has banded cloud features and giant long lasting storms such as the Great Red Spot. Has a powerful magnetic field. Visited by many spacecraft, orbited by Galileo. Juno probe is en route to the planet.

Satellites of Jupiter[]

See Jovian System for all moons
  • Io - Jupiter's volcanic moon.
  • Europa - Smooth and bright moon of Jupiter. Its surface is covered with linear grooves, possibly cracks in a frozen ocean. One of most likely places to find life outside of Earth.
  • Ganymede - Largest moon of Jupiter and in the solar system. Larger than the planet Mercury, though not as massive. Only moon known to generate its own magnetic field. Only body other than Earth known to have plate tectonics.
  • Callisto - Furthest of Jupiter's major moons, Callisto is a dead world unlike its siblings. It is considered the most heavily cratered surface in the solar system and therefor has the oldest surface.
