Brown dwarfs are often referred to as "failed stars" because they are too massive to be considered a planet, but too small to initiate nuclear fusion in their cores like a star. Jupiter is similar in size to many known brown dwarfs and is sometimes used as a reference point when comparing these objects. Red dwarfs are much larger and brighter than brown dwarfs, white dwarfs are the remnants of once-larger stars, and Bok globules are dense clouds of gas and dust that may give birth to stars and planets but are not themselves a comparable size to brown dwarfs.
