Planets are destructible voxel objects with their own Gravity field, atmosphere, vegetation, and hostile life. They are similar to Asteroids in that they're fully destructible voxels, and have randomly generated Ores but that's where their similarities end. Planets range in size from
120km in diameter. By default, each planet comes with it's own accompanied Moon, unless manually spawned in by a player. Moons and Planets are exactly the same objects technically and are very similar in practice, with a few key differences being: Moons are usually much smaller often only
38km in diameter and possess much weaker gravitational fields - down to 0.25 g. That said the moons of Jupiter and Neptune have shown to be near the size of Earth and near Earth’s pull in gravitational force. The key difference between a moon and a planet is a moon orbits a celestial body that is not a star.
Much like Asteroids they are completely immobile and never will move no matter how much force is applied, and are themselves not in anyway affected by gravity. If two planets were spawned very close to each other inside both of their gravitational fields, niether of them would ever fall into each other and meet. Although objects would experience some very strange gravitational effects from both of them.
While their surface appears randomly generated, they're in fact pre-loaded voxel models. There is no procedural generation with Planets or Moons. When the size of the Planet is increased, it actually stretches the models to accommodate for the new size. The textures and vegetation aren't stretched, only the surface model is. Each planet type Earth, Mars, and Alien will spawn the appropriate models and surface textures associated with them. The same properties are applied even when it is spawned in manually by the player via (default) -
