Star

A star was an enormous sphere producing heat and light (in essence, it was 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 were seen orbiting medium mass orange-yellow stars, often called suns.

Stars visibility was measured in magnitudes. An Imperial Class Star Destroyer was undetectable against the background of a first-magnitude star, even with the best instruments.

It was estimated that there were four hundred billion stars in the galaxy. There were 7.1 billion habitable stars in the known galaxy, which made up about 3.2 billion habitable star systems. This means that many systems contained two or more stars. Red dwarfs accounted for approximately 70 percent of the galaxy's stars.
