LIST OF BROWN DWARFS

The first free-floating brown dwarf discovered is Teide 1 in 1995. The first brown dwarf that orbits the star is Gliese 229 in 1995 also. The first brown dwarf to have planet is 2M1207, discovered in 2004.
Since if brown dwarf sits between planet and star, it is also called planetar or hyperjovian. The designation starts with lower case 'b' or upper case 'B' if brown dwarf orbit the parent primaries.
The following is the list of 38 preferred brown dwarfs out of 608 total brown dwarfs. Although some extrasolar planets can turn to brown dwarfs since most have only minimum masses because their inclination of the orbit is not known. The more massive the extrasolar planet is, the more likely it’ll turn to brown dwarf. Examples include HD 114762 b (>11.02 M_J), Pi Mensae b (>10.35 M_J), HD 136118 b (>11.9 M_J), and NGC 2423-3 b (>10.6 M_J).
