View from a planet.

Planets are large objects composed of rock or gas that orbit around a star. Planets come in all shapes and sizes, from small dwarf planets to giant gas giants. Planets, like with many other objects, can be procedurally generated in SpaceEngine.

List of planet classesEdit

Here's a list of planetary classes as of version 0.9.8.0:

  • Selena: rocky planets without an atmosphere. Mercury and the Moon are examples
  • IceWorld: A planet whose surface is covered primarily by solidified volatiles
  • Titan: Planets similar to the moon Titan mainly composed of rocky material, water ice and organic compounds
  • Desert: a planet with atmospheric pressure greater than 1 nanobar, but with no liquids on its surface
  • Terra: rocky planet whose primary component is silicates (rocks)
  • Oceania: a planet with a global ocean, completely covering the surface
  • IceGiant: Gaseous planets composed of heavier elements like carbon, sulfur, oxygen and nitrogen. Uranus and Neptune are examples.
  • GasGiant: surfaceless planets composed of gases such as hydrogen and helium. Jupiter and Saturn are examples.

As of September 2017, SpaceEngineer has been working on new class parameters. These proposed classes are as follows:

  • Airless: a planet with an atmospheric pressure less than 1 nanobar
  • Desertic: a planet with atmospheric pressure greater than 1 nanobar, but with no liquids on its surface
  • Lacustrine: a planet with a small amount of liquid on its surface (lakes), and, obviously, with an atmosphere (because liquid cannot exist in a vacuum)
  • Marine: a planet with seas of a liquid substance, i.e. a significant amount of it, but not completely covering the surface
  • Oceanic: a planet with a global ocean, completely covering the surface
  • Superoceanic: a planet with a very deep ocean (hundreds of kilometers deep), with exotic forms of ice forming on its bottom (ice VI and ice VII)
  • Ferria: metals (iron, nickel) and siderophilic elements such as sulfur
  • Carbonia: carbon and its compounds like carbides, also CO and methane.
  • Aquaria: water in the form of exotic ices and liquid
  • Jupiter: hydrogen and helium
  • Neptune – not any of the previous classes. Typically, H/He is less than 25%; other substances are water/ammonia/methane and a rocky core. An aquaria with a supercritical vapor atmosphere is classified as a minineptune/subneptune
  • Chthonia – core of an evaporated ice/gas giant, or a helium-rich giant
