On the other hand, Desolo and Novus have 1/2 the diameter of a planet, meaning that they have 1/8th of the volume. The five planets (Atrox, Calidor, Glacio, Sylva, and Vesania) share the same size and gravity. Planets have unique day/night cycles and power generation, with some planets being better for solar power, and others for wind power. Research Items and Samples are also different per planet, with different colors, amounts of bytes, and research times. Atrox is unique in having four atmospheric resources, with one being unique to the planet, while Desolo, having no atmosphere, has no atmospheric resources. Planets share the same universal resources, while all but Atrox have a Primary and a Secondary resource, which each exists on only two planets.

Planets are procedurally generated upon creation of a new save, each having unique characteristics, with different types of Flora, Biomes, and Resources. The moons, Desolo and Novus, orbit Sylva and Vesania, respectively. These are, starting from the one closest to the Sun, Atrox, Calidor, Sylva, Vesania, and Glacio. There are currently five planets, with two moons. Moons exist as well, but they share the same characteristics as planets, and are treated as such. Planets are astronomical bodies in Astroneer that the player may travel to, explore and construct bases on.
