Planets

In Astroneer, a planet is an astronomical body the player can visit. Different than in real-life astronomy, in the game, celestial bodies that orbit other planets are not called moons, but also planets.

The solar system in Astroneer consists of a central star, the Sun, and seven planets. Of these, five would be characterized as terrestrial planets in astronomical terms. These are, starting from the one closest to the Sun,, , , , and. The other two bodies, and, would actually be classified as moons of Sylva and Vesania, respectively.

Planets in-game are procedurally generated, broadly spherical worlds, each with a unique look. Each planet offers a unique set of naturally occuring resources, flora, and collectibles. They also differ among multiple dimensions, in particular, size, gravity, length of solar days, effectiveness of power generation using solar or wind energy and the number of Gateway Chambers.

The surface of each planet is divided into distinct biomes, which again differ in several ways. Internally, most planets are structured as rigid bodies with three distinct layers: An inner core, an outer core, a mantle, and a crust, each again with differing sets of resources and native flora. Surprisingly, extensive cave systems penetrate most of the planets interior, sometimes stretching from the surface down to the outer core.

Also, all planets except Desolo feature an atmosphere from which the player can extract various atmospheric resources. All of these features combined also affect the difficulty of operating on each of the planets.

The list below lists all planets in the game as well as, inter alia, which unique set of resources is available.

List of Planets

 * Primary resources are found between the first underground layer and the mantle of the planet. Secondary resources are found in mountainous biomes on the surface and the layers under the mantle to the core.

Planet Types
The Planets in Astroneer each have a type associated with them. Each type has varying differences, from the amount of sun to the types of resources that it may contain.

Landing Zones
Landing Zones are locations on each planet that a player may land on using a Shuttle. Landing zones are marked with a sphere when viewed in orbit around the planet, allowing the player to select the zone to land in that location.

Landing Zones appear naturally at the start of the game, or from the use of a Landing Pad. If a Landing Pad is used in or near another landing zone, they may overlap and the player may have trouble selecting the proper zone to land in. Landing Pads do not have Beacons, so they may be hard to distinguish from naturally occurring Landing Zones. In multiplayer, a passenger is also able to select a landing zone to land on, not only the person in the main seat.

Trivia

 * Some of the planets are loosely based on the Solar System. Sylva and Desolo are both based on Earth and the Moon, Atrox is based on the toxicity of Venus, Calidor on Mars, and Glacio could be based on either Uranus or Neptune, as both have icy cores. Vesania and Novus could be based on Jupiter or Saturn's moons.
