Brown dwarf star Gliese 229b: Artist's view of the brown dwarf star Gliese 229 B seen from a possible satellite. Discovered in 1995 in the constellation Lievre at 18 light years from Earth, this brown dwarf is 30 to 40 times more massive than Jupiter and would be 2 to 4 billion years old. Top left is the red dwarf star Gliese 229A. This is how the brown dwarf Gliese 229b might appear from a satellite. Gliese 229 b was discovered in 1995 and is 19 light years from the Earth. This brown dwarf orbits the red dwarf Gliese 229A in the constellation Lepus. Gliese A can be seen shining dimly on the upper left. These two dwarfs are about four billion miles apart, about the same distance between Pluto and our sun
