Mass of Jupiter.
Nov 30, 2005 Astronomers from Penn State University and the Harvard-Smithsonian Center for Astrophysics have found a miniature solar system in the making. A failed star with a hundredth the mass of our own Sun seems to have a planet forming disc of dust and gas surrounding it. With only 8 times the mass of Jupiter, this brown dwarf star is more like a large planet, and yet it's capable of forming a planetary system of its own.
