First Mini Me Solar System Found, Huge Planet Orbits Tiny Brown Dwarf Star
Astronomers have found the first planet orbiting a brown dwarf star. The system is a miniature version of our own solar system, a kind of Mini Me Solar System. Observations of accretion disks around young brown dwarfs have led to the speculation that they may form planetary systems similar to normal stars. While there have been several detections of planetary-mass objects around brown dwarfs (2MASS 1207-3932 and 2MASS 0441-2301), these companions have relatively large mass ratios and projected separations, suggesting that they formed in a manner analogous to stellar binaries This artist's conception shows the relative size of a hypothetical brown dwarf-planetary system compared to our own solar system.
