Stars were massive, glowing, spheres of plasma and gas that produced their own light and energy. Stars that were the central body of a planetary system were referred to as suns.

- "When I served under Leia... She would say that hope is like the sun. If you only believe in it when you can see it-"
"You'll never make it through the night." - ―Amilyn Holdo and Poe Dameron

The star Kessa
Stars were large celestial bodies that generated heat, light and radiation and consisted of a mass of burning plasma and gas.[3] Resistance member Karé Kun once referred to them as "giant balls of exploding gas."[4] During the High Republic Era, stars were assigned to a specific class by their chemical properties, such as R-class stars being unusually nitrogen-heavy.[5]
Types of stars[]
There were seven types of main sequence stars in the galaxy:[6]
- "A" stars were white, and had a lifespan of four hundred million to two billion years. Example: Colu.[6]
- "M" stars were red and emitted little light or heat. They had a lifespan of over one hundred trillion years. They were also called red dwarfs. Example: Barab.[6]
With O-class stars being the biggest in the sequence, the size decreased gradually to the smallest M-class stars.[6]
The non-main sequence stars include:[6]
Pre-main sequence (smaller than M-class stars):[6]
- Brown dwarf. Example: Doornik-1142.[6]
- Protostar. Example: Black Bantha Nebula.[6]
Post main-sequence (bigger than O-class stars):[6]
- Red giant. Example: Sokor.[6]
- Blue giant. Example: Ku'Baku.[6]
- Red supergiant. Example: Primus Goluud.[6]
Compact stars:[6]
- White dwarf. Example: Ardos.[6]
- Black dwarf. Example: A star in the The Ring.[6]
- Neutron star. Example: Oolex pulsar.[6]
- Black hole. Example: Endor Gate.[6]
Other exotic star types existed that did not fit precisely into this system of classification. These included Asar, considered a blue dwarf,[7] and yellow dwarfs.[8]
Starbirth[]
Stars formed in areas of space known as stellar nurseries,[9] through a collision of energies in the form of pressure and heat, a process which shaped the space around it and could be seen from millions of kilometers away.[10] The ignition of a planet's core by an outside force could also result in the formation of a star.[11] After their birth, stars went through various stages during their life, such as a yellow dwarf expanding to become a red giant.[8] Plants drew sustenance from sunlight.[12]
Stars and planets[]

A field of stars
- "There are so many! Do they all have a system of planets?"
"Most of them." - ―Anakin Skywalker and Jedi Master Qui-Gon Jinn, looking at the stars
Most stars were orbited by a set of planets and other bodies.[13] In that case, they were referred to as suns. A sun, together with all the bodies bound to it, formed a planetary system. In some cases, a planetary system could contain several suns, as was the case around the planets of Tatooine[14] and Mon Cala.[15]
A planet revolving around a star normally received light and warmth from it,[8] although there were exceptions. Umbara was known as the "Shadow World" because the rays of its sun never completely reached the planet's surface, keeping it in perpetual darkness.[16] In the night sky, remote stars looked like mere points of light.[13] By convention, those points of light were grouped into constellations.[17] Without a star, most worlds would become lifeless and frozen. The size and distance of a sun would affect many of the features of a planet orbiting it.[18]
On the planet Coruscant, stars were hard to see, due to all the city lights of the sprawling ecumenopolis. However, according to young Obi-Wan Kenobi, one could see them if they knew how to look. Stars could be used for navigation: When young Kenobi returned to the Jedi Temple after trying to help fellow Jedi Initiate Gehren Rand, who had run away, he used the stars to find his way home.[19]
