An artist’s rendition comparing brown dwarfs to stars and planets. All objects are plotted to the same scale. On the far left is the limb of the Sun. To its right is a very low mass star (an “late-M dwarf”). The next two objects are brown dwarfs (a hotter “L dwarf” and a cooler “T dwarf”), followed by Jupiter.
