Star

A star (or "sun") is a massive energy-producing sphere of plasma and gas located in space. The region around a star that is held by its gravity, including any planets, moons, comets, and asteroids, is called a planetary system.
== Life cycle ==
A star is formed by a nebula that collapses under its own gravity, the gas of the old nebula forms now a young new born star. Some very weak stars have a lifetime of trillions of years, stars like our sun have a lifetime of several billion years, stars stronger than our sun have a life that is below the billion (some stars life even shorter than 10,000 years!). When stars die most of them becomes slowly dying white dwarfs and end after a very long time cold and dead black dwarfs, the stronger stars dies with a supernova and end up as a neutronstar, quarkstar, preonstar or a black hole.
== Large stars ==
Large stars are another type of star and are normally Giants, Super Giants, and Hyper Giants and normally don't have planets around them, the rarest ability of these large stars are to have planets (one example: Tymos Majoris).
