Planets are extraterrestrial, spherical, huge "rocks" which have a variety of features and inhabitants. In Starbound, these are practically worlds you can travel between in a Spaceship. Planets in Starbound are entirely procedurally generated and filled to the brim with unique content. Not only is the terrain of the planet procedurally generated, but also the weather, the gravity, the difficulty level, the plant life, the behavior and appearance of alien creatures, and much more. Some planets may house Fossils. Non-homeworld planets will most likely have "bookmarks" you can set.
Every planet has unique coordinates in the navigation console. The procedural generation engine is tied to these coordinates in a way where the coordinates can be shared among others.
Difficulty is related to the damage that enemies do as well as their health. It may also relate to environmental conditions which require advanced tools. Planet difficulty is assigned to each planet as a number between 1-10 (previously 1-100 before Irritated Koala Update) — the higher the number, the more difficult the planet. It's been stated that level 10 planets will "always be hard" no matter the gear the player has acquired.
To see a list of planetary biomes, visit the Biomes page.
Each planet has an environment made up of a number of elements. The background, terrain type, plant type, weather, and temperature are called the biome of the planet. While biomes on different planets of the same type will have certain features in common, they will be unique in their combination of smaller elements through procedural generation.
Temperature may be either too hot or too cold for the player to survive. These planets require special equipment to navigate. Similarly, there are other conditions that may make a planet dangerous such as lack of atmosphere or a gaseous surface which also require special tools or equipment.
Planets will have different ambient light depending the type of star they orbit and how close they are to said star. For example if a planet is orbiting very close to a Red Dwarf star, the planet will have a deep red ambient light.
Once you have claimed a planet as a homeworld , you can transform it however you want. Whether by terraforming it, building a weather station to change the weather, or anything else. Claimed homeworlds can be renamed.
Multiple planets can be designated as homeworlds , but the cost is so high in resources that a single player may have trouble doing so. Homeworlds can be set to not allow explosions to prevent griefing.
Planets that have air can have various mobs, and bases from any races, such as an Avian temple, Apex base, or a Floran tribe.
There is currently no way to dig through to the other side of a planet (it's probably going to stay that way). Once you reach the core, you can dig no deeper.
It is possible to fly from a planetary surface into orbit. There are meteorite rocks and monsters, but it's very cold, which makes survival difficult.
Recently with a new feature you can see planets within your star system in the background.
- There once was a bug in which you landed on a wall block, not a block.
- The planet name Magrathea is a reference to Hitchhiker's Guide to the Galaxy.
