Planets come in 3 sizes, and their Moons come in 4, smaller, sizes. The size of a Planet not only affects their circumference, but also the distance to the magma core as well as the distance to the upper atmosphere (space layer). There are four possible sizes for each world. How far one has to travel is dependent upon the planet's size. The player can continue in one direction on a planet and appear in the position that they began in, implying that these planets are spherical. These planets' appearances are determined by their biome, size, and current distance from the player. When on the surface of a planet, nearby planets within the currently occupied star system can occasionally be seen. According to SteamSpy, there are also approximately 3,172,227 copies of the game currently in existence on Steam (bought games and games activated via key) as of April 1st, 2018. There are 12.667 quadrillion planets able to be generated within the game currently, with 422.22 quadrillion planned. These coordinates act as seeds to the game's internal random number generator, and as such, will always produce an identical planet when used. These elements include a planet's terrain, layers, biomes, sub-biomes, weather, gravity, difficulty, plants, trees, and the appearance and behavior of its fauna.Įvery planet has unique coordinates in the navigation console. Almost every element of a planet is procedurally assembled by the game's engine.

Planets are the primary location of gameplay in Starbound.
