Explore: Brown Dwarf Stars

Brown dwarfs are substellar objects that have more mass than the biggest gas giant planets, but less than the least massive main-sequence stars. Their

lowest-mass M dwarfs are expected to be brown dwarfs, not true stars, and so those would be excluded from any definition of red dwarf. Stellar models

A sub-brown dwarf or planetary-mass brown dwarf is an astronomical object that formed in the same manner as stars and brown dwarfs (i.e. through the collapse

A dwarf star is a star of relatively small size and low luminosity. Most main sequence stars are dwarf stars. The meaning of the word "dwarf" was later

G-type main-sequence stars include Alpha Centauri, Tau Ceti, and 51 Pegasi. The term yellow dwarf is a misnomer, because G-type stars actually range in color
