SUMMARY: One of the most difficult tasks for astronomers is to figure out how massive distant objects are. Once you find objects orbiting one another; however, it's relatively easy to do. The Hubble Space Telescope has helped astronomers measure the mass of a binary pair of brown dwarfs - failed stars - as they orbit one another. One dwarf is 55 times the mass of Jupiter, and the other is 35 times the mass. Each would have to be 80 times the mass of Jupiter before they had enough mass to ignite a fusion reaction.

Hold the phone, 55 + 35 = 90 jupiter masses, so we just get these two to collide and hey presto and brand new solar system for the future of mankind.

I wonder how many years worth of the energy from the new combined star it would take to get these two to spiral together. Of course then, we might need to wait a little while for the new combined star to settle enough to be safe to get near.
