In our local galactic neighbourhood, lying 3rd closest to the earth is Luhman 16, this is a binary brown dwarf system. This star system consists of two brown dwarf stars. Luhman 16A is a L class brown dwarf. It would glow faintly red to our eyes. Studies have suggested that Luhman 16A has large bands similar to a gas giant planet.

Luhman 16B is a T class brown dwarf. This would glow faintly pink or purple to our eyes. These brown dwarfs orbit their common centre of mass with a distance of roughly 3.5 astronomical units
