A star is a sphere that is mainly composed of hydrogen and plasma, held together by gravity and is able to produce light through nuclear fusion. Stars exhibit many diverse properties, resulting from different masses, volumes, velocities, stage in stellar evolution and even proximity to earth. Some of these properties are considered extreme and sometimes disproportionate by astronomers.

edit- ^ a b c d e f Other than the Sun
- ^ An "average" star is a normal star which is larger than a red dwarf, but smaller than a giant star. Depending on the definition, this can also be called "Sun-like star".
- ^ a b c d e f g A normal star is a star that is past its protostar period, in its main fusion period, before becoming a degenerate star, black hole, or post-stellar nebula, and is not a failed star (brown dwarf).
- ^ a b c Not including stellar-mass black holes, or exotic stars
- ^ a b c d By visual magnitude (m)
- ^ a b c d e f g This is the appearance in the sky from Earth.
- ^ This does not include brightest stars due to outbursts
- ^ a b c Luminosity here represents how bright a star is if all stars were equally far away, in visible light.
- ^ a b c Energetic here is the total electromagnetic energy emitted by a star in all wavelengths.
- ^ Not including stellar black holes
- ^ Stars with particularly high radial velocities are usually erroneously recorded, so all large values should be taken with a grain of salt.
- ^ a b The allowable distance between components of a star system is debated.
