Physical Realm
Astronomy is all the space objects in the cosmere, including shardworlds and minor shardworlds, suns, stars and moons.
The cosmere is a fictional universe, but it can also be considered the dwarf (miniature) galaxy that contains everything mentioned here.[1]
The Selish System
The Selish System orbits a yellow star named Mashe. It has two gas giants, named Ky and Ralen, and a dwarf planet.
Donne
Donne is the closest planet to the sun. While it is in a habitable region, it is barren and suffers from terrible dust storms.[2]
Sel
- Main article: Sel
The second planet from the sun, Sel was an Earth-like Shardworld inhabited by humans and artificially created beings called Seons and Skaze. The planet was the location of Elantris. Sel was dominated by the Fjordell Empire, with Arelon and Teod being the only remaining free nations. All these nations (except Teod which is located on a continent to the north) were situated on the continent of Opelon (named Sycla by the Fjordell Empire).
Moons
Sel has a single moon named Oem.
The Scadrian System
The Scadrian System has a yellow sun. It has five planets: Scadrial within the system's habitable zone; two gas giants, named Aagal Nod and Aagal Uch; and finally two dwarf planets.[2]
Scadrial
- Main article: Scadrial
The planet was created by the Shards Ruin and Preservation. The orbit of the planet has been changed by people using Investiture. Its size and gravitation are 1.0 cosmere standard[2].

Threnody
- Main article: Threnody
Threnody is the minor Shardworld that contains the Forests of Hell. It is the setting for the story Shadows for Silence in the Forests of Hell. It has many features that are similar to Earth, including forests, mountains and oceans. Silver seems to be a fairly common resource on the planet, but because of its importance to survival, it is still finite and valuable.
The Drominad System
The Drominad System has four planets in the habitable zone, three of which have developed human societies. There are three gas giants. There is also an asteroid belt between the habitable zone and the gas giants.[2]
First of the Sun

Roshar
- Main article: Roshar

Roshar has three moons. The first moon is Salas. It is violet, and is the smallest moon. The middle moon is Nomon, which is a bright, pale blue. And the final moon is Mishim, which is small and green.
Braize
- Main article: Braize
Braize is the third planet from the sun. Odium settled on Braize, although he is still effecting Roshar. Braize is unlikely to get its own books, but scenes from The Stormlight Archive will be set on Braize.[citation needed]
Other Planets

Stars and Constellations
Starbelt
The Starbelt is an unusually bright patch of stars in the sky of Threnody.[10] It is useful for navigation in the Forests of Hell during the night; the light usually filtered through the trees fairly well.
The Starbelt is the same patch of unusually bright stars that is visible from Scadrial.[11] It is visible from other worlds in the Cosmere as well.[12]
Taln's Scar
