Planets in Starbound are entirely procedurally generated and filled to the brim with unique content. Chucklefish went into the planet generation with one simple goal: no two planets should be the same. As such, even the smallest details are procedurally generated. Not only is the terrain of the planet procedurally generated, but the weather, the gravity, the difficulty level, the plant life, the behavior and appearance of alien creatures, and much more all contain random or procedurally generated elements.

The seed for the procedural generation of a planet is based on its coordinates. This means that two players exploring the same coordinates will encounter the same environment. Many coordinates, however, will not yield a planet, simulating the emptiness of space in reality.[1]


All planets have a finite depth, which will end at an undetermined depth, but not all planets are the same size. Round planets vary in size, and can be circumnavigated: traveling far enough in one direction will bring the Player back to where they started. However, Chucklefish has stated that their engine can support infinite planets.[1]

Planetary CoreEdit

If the Player digs deep enough, they may reach a planet's core. Many planets have a molten core which kills anyone on contact, -the molten core kills over a duration the same as any lava- but a planet's core can also be made of some other impassable material. 

Interestingly if you bring an easy to mine material down to a planets molten core it is possible to overlay the lava with for example Dirt. if you place enough dirt mineral deposits that were hidden by the lava may be revealed, as you can see in this image i'm deep in the lava core and have revealed silver and Iron deposits.

Be careful though even a single cube of lava is HIGHLY pressurised even after being Isolated as this before and after show

one cube Isolated
