Star
From Wookieepedia, the Star Wars wiki.
A star is an enormous sphere of immensely hot hydrogen and helium that undergoes nuclear fusion[source?] to produce heat and light (in essence, it is a giant ball of plasma). Systems of planets would usually form around stars when the gas and dust around them became stable enough. Stars could come in all sorts of sizes, colors, and temperatures. Most planets are seen orbiting medium mass orange-yellow stars, often called suns.
It was estimated that there are four hundred billion stars in the galaxy. There are seven billion one hundred million habitable stars in the known galaxy.[1] Red dwarfs account for approximately 70 percent of the galaxy's stars.[2]

[edit] Types of stars
There are seven types of main sequence stars in the galaxy:[1]
"O" stars are blue and hot. There are approximately one hundred million habitable O stars in the galaxy and they have a lifespan of less than one million years. Example: Garnib.
"B" stars are blue and hot. There are approximately one hundred million habitable B stars in the galaxy and they have a lifespan of ten million years. Example: Kessel.
"A" stars are white and hot. There are approximately one hundred million habitable A stars in the galaxy and they have a lifespan of four hundred million to two billion years. Example: Colu.
"F" stars are yellow-white and medium-temperature. There are approximately one hundred million habitable F stars in the galaxy and they have a lifespan of four billion years. Example: Ropagi.
"G" stars are yellow and medium-temperature. There are approximately two billion habitable G stars in the galaxy and they have a lifespan of ten billion years. Example: Corellia.
"K" stars are orange and cool. There are approximately three hundred billion seventy-five million habitable K stars in the galaxy and they have a lifespan of sixty billion years. Example: Yavin.
"M" stars are red and cool. There are approximately seven hundred million habitable M stars in the galaxy and they have a lifespan of approximately one hundred trillion years. Example: Barab.
In addition to the main sequence stars, there are five hundred habitable non-main sequence stars in the galaxy.
