List of planet types

From Ultronomicon
Revision as of 18:43, 23 October 2004 by Jacius (talk | contribs) (*phew* Moved all the information from the individual type pages to this page, and organized and cleaned them up. Very many types of planets have no information, so I put them in a list at the end.)

Notice: Many world types do not yet have information in the Ultronomicon. You can help by adding information about these types.

There are many types of planet in the universe. All planets of the same type are similar in color, mineral types, and general conditions (such as atmosphere and seismic activity). With the exception of Gas Giant, a moon may be any of these types as well.

Types with information


Auric Worlds are worlds made of gold and gold compounds. These worlds are rich in precious metal minerals. They appear yellow from space.


Lanthanide Worlds are worlds composed of the heavy rare earth elements. They are rich in elements like Ytterbium, Cesium, and Lanthanum. They appear yellow from space.


Magma Worlds are worlds whose outer crust has been destroyed or weakened to a point where lava and other liquid metals from the core of the planet spew across the surface constantly. They are rich in radioactive, precious, and base metal minerals. The surfaces are extremely hot and any landings should be made with extreme caution unless landers have proper shielding. Magma worlds appear red-orange from space.


Radioactive Worlds possess good deals of radioactive minerals. Although they give a nice reward, they are fairly hard to find. They appear bright orange from space.


Rainbow Worlds are the garbage dumps supposedly built by the Precursors. There are only 10 in existance, but they are said to be arranged in a pattern that would be a clue to the Precursors' fate. The Rainbow Worlds possess good mineral yields, but more importantly, the Melnorme will give 500 credits for each one you find. Rainbow worlds appear yellow from space, but from orbit appear to have colors from across the spectrum, hence their name.


Ruby Worlds are a very rare type of planet, usually with a horrible surface temperature, no atmosphere, and a lot of tectonics. They contain the coveted exotic minerals, especially Neutronium and Tzo Crystals.


Water Worlds are planetary bodies in which the majority of the surface is covered in water (or ice). They are uncommon in the galaxy. When found within more moderate orbits, however, they have a higher chance of having life evolve on them. Many of the advanced races' homeworlds are water worlds, including Earth.

Water worlds typically are rich is base metals, though rare deposits of radioactive and corrosive metals can sometimes be found on the more degenerate water worlds. They appear blue from space.


Yttric Worlds are worlds composed of Yttrium and Ytterbium. They hold rare earth metals and base metals.
