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...

list of notable brown dwarfs. These are objects that have masses between heavy gas giants and low-mass stars. The first isolated brown dwarf discovered was...

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...

These red dwarfs have spectral types of L0 to L2. There is some overlap with the properties of brown dwarfs, since the most massive brown dwarfs at lower...

An object with a spectral type Y (also called Y dwarf) is either a brown dwarf or a free-floating planetary-mass object. They have temperatures below around...

object with the spectral type T (also called T dwarf or methane brown dwarf) is either a brown dwarf or young free-floating planetary-mass object. A...

The brown-dwarf desert is a theorized range of orbits around a star within which brown dwarfs are unlikely to be found as companion objects. This is usually...

An object with the spectral type L (also called L-dwarf) can be either a low-mass star, a brown dwarf or a young free-floating planetary-mass object. If...

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...

This list covers all known stars, white dwarfs, brown dwarfs, and sub-brown dwarfs within 20 light-years (6.13 parsecs) of the Sun. So far, 131 such objects...

"Yellow" dwarfs such as the Sun are white, "red" dwarfs are a deep shade of yellow/orange, and "brown" dwarfs do not literally appear brown, but hypothetically...

J1407b is a substellar object, either a free-floating planet or brown dwarf, with a large circumplanetary disk or ring system. It was first detected by...

2MASS J04442713+2512164 (2M0444, IRAS 04414+2506) is a brown dwarf in the Taurus Molecular Cloud. It is surrounded by a protoplanetary disk, which is...

This is a list of stars, neutron stars, white dwarfs and brown dwarfs which are the least voluminous known (the smallest stars by volume). This is a list...
