BD+20 307 System

Exoplanetary Scratchpad [SysBP Img]

Close binary star with an age comparable to the Sun's. It has a 1 million times as much dust as the Solar System which points to a very recent (less than 100,000 years) collision between two terrestrial planets. This would be the first evidence of any planets in a close binary system.
