Procedural Pixels - Planets is an asset containing 8 different 2D pixel planet generators that enables you to create an unlimited number of various looking planets as you can imagine.
The asset is very easy to use: just drag and drop the prefabs into a scene and press the generate button in the inspector to get unique appearances each time.
Each planet generator has several parameters you can change including dimensions, colors and more individual ones for each type of planet. It is also possible to save the sprites if you want to use them or edit them outside Unity.
Included is also a meteoroid generator and a demo scene of the solar system created by using the different generators.
