The '''Rosharan system''', also known as '''Greater Roshar''', is the name given to the planetary system containing the [[Cosmere#Planets|planet]] called [[Roshar]].{{au ref|Roshar}} It comprises thirteen planets, three of which are inhabited, as well as the usual asteroid belt, and three moons for a total of sixteen orbital bodies -- an important number in the [[cosmere]].{{map ref|Roshar system}}

The Greater Roshar system is composed of three terrestrial planets and ten gas giants, divided by the asteroid belt. Starting with the sun, the celestial bodies in the system are:

The'''[[Ashyn]]''' is the closest planet to the Rosharan system's sun.
 
While there are humans inhabiting this planet, a global cataclysm at some point in the past has forced most of its inhabitants to flee to Roshar, while the remainder lives in floating cities in the sky and in small areas of habitability.{{au ref|roshar}}{{book ref|tsm|2}}{{wob ref|9847}} The cataclysm was likely caused by overuse of [[Surge]]s by Ashynites, and has left the surface highly volcanically active. There is a known manifestation of Investiture on Ashyn, based around Surge-granting diseases, but no known Shard.{{wob ref|6646}} In Rosharan mythology, Ashyn is referred to as the [[Tranquiline Halls]].{{book ref|row|17}}
 
Ashyn has a notable axial tilt, allowing it to experience seasonal variation.{{wob ref|11448}}

;[[=== Roshar]]: ===
The'''[[Roshar]]''' is the second planet is the eponymous planet of Greater Roshar. The [[Shard]]s of [[Honor]] and [[Cultivation]] can be found here. Roshar features a single supercontinent, also called Roshar, on which its inhabitants live. Its semi-major axis is such that it has an orbital period of approximately 1.1 years.{{wob ref|8928}}{{wob ref|3781}}{{wob ref|5569}}{{wob ref|10572}}
 
Roshar has a surface gravity or approximately 0.7g, and a radius of approximately 5663 kilometres, just under 0.9 cosmere standard.{{au ref|roshar}}{{wob ref|10231}} The planet has a substantial atmosphere, and has a partial pressure of oxygen that is higher than standard cosmere.{{au ref|roshar}}{{wob ref|1806}}
The planet has no axial tilt.{{wob ref|11448}} It has a solar day of 20 Rosharan hours.{{wob ref|248}}

Three moons, [[Roshar#Planetary System|Salas, Nomon, and Mishim]], orbit the planet in unstable, highly eccentric orbits.{{map ref|Roshar system}}{{wob ref|8096}}{{wob ref|12702}}
The majority of the Rosharan System's sentient lifeforms lives on Roshar.
 
;[[=== Braize]]: ===
A'''[[Braize]]''' is the third planet from the Rosharn system's sun.{{book ref|sa4|80}}{{map ref|Roshar system}} It is a cold planet, perhaps outside the habitable zone. While no humans live here, there do exist self-aware Splinters that inhabit either the planet or its Cognitive manifestation.{{au ref|Roshar}} Braize is where the Shard of [[Odium]] resides.{{wob ref|9847}} In Rosharan mythology, Braize is referred to as [[Damnation]], and is where Rosharan Heralds returned to between [[Desolation]]s.{{book ref|sa3|121}}

Beyond the asteroid belt are ten gas giants. These outer planets, which are designated by [[Ten Essences|Vorin numerals]], are '''Jes''', '''Nan''', '''Chach''', '''Vev''', '''Palah''', '''Shash''', '''Betab''', '''Kak''', '''Tanat''', and '''Ishi''', in order of increasing distance from the sun.
