A star is any massive self-luminous celestial body of gas that shines by radiation derived from its internal energy sources. Of the tens of billions of trillions of stars composing the observable universe , only a very small percentage are visible to the naked eye. Many stars occur in pairs, multiple systems, and star clusters. The members of such stellar groups are physically related through common origin and are bound by mutual gravitational attraction. Somewhat related to star clusters are stellar associations , which consist of loose groups of physically similar stars that have insufficient mass as a group to remain together as an organization. This is a list of significant stars ordered alphabetically by the constellations in which they appear, followed by a list of significant star types.
The following are lists of stars. These are astronomical objects that spend some portion of their existence generating energy through thermonuclear fusion. The following is a list of particularly notable actual or hypothetical stars that have their own articles in Wikipedia, but are not included in the lists above. From Wikipedia, the free encyclopedia.

Twelve players—five starters and seven reserves —from each conference are chosen from what used to be a pool of players—60 players from each conference with 24 guards and 24 frontcourts forwards and centers —listed on the ballots by a panel of sport writers and broadcasters to all active players. The starters are chosen by a combination of fans, media, and current players. Coaches are not allowed to vote for their own players, and can select two guards, three front court players, and two players regardless of positions. For instance, Michael Jordan was named to the All-Star Game roster 14 times, but missed the game due to injury.
