List of least massive stars
This is a list of the least-massive known objects in galactic orbit known, and includes free-floating planetary-mass objects (sub-brown dwarfs), brown dwarfs, and the least massive red dwarfs. It is ordered by mass, both in units of solar mass (M☉) and Jupiter mass (MJ).
Brown dwarfs are listed with a brown background, red dwarfs with a magenta background, and sub-brown dwarfs with a gray background. The Sun and Jupiter are included as references, with a yellow and lighter gray background, respectively.
Although brown dwarfs lack sufficient mass to ignite core hydrogen fusion (75–87 MJ, depending on metallicity), the smallest true stars (red dwarfs) can have such low atmospheric temperatures (below 4,000 K), that it is difficult to distinguish them from brown dwarfs. A brown dwarf's mass cannot be lower than 13 MJ, because the heat produced via gravitational pressure below this critical point is insufficient to fuse deuterium in the core. A brown dwarf, therefore, is heavier than a gas giant, but not quite massive enough to be a star.
List of least massive stars[edit]
Objects with an estimated mass of 0.1 or smaller M☉ (red dwarfs, brown dwarfs and sub-brown dwarfs) are included. Masses are their current (evolutionary) mass, not their initial (formation) mass. The Sun and Jupiter was added to reference.

Cha 110913-773444[edit]
The object Cha 110913-773444 is sometimes referred to as being the smallest brown dwarf, but its mass is too light for this (8 MJ). It is even less massive than some known exoplanets. Therefore, it can better be considered a sub-brown dwarf or a planemo. Some stars are listed as red dwarfs although they should be listed as brown dwarfs due to their mass, and vice versa.
