BD +20°307 is a binary star system, located about 300 light-years away in the constellation Aries. Each component of the binary is slightly more massive than the Sun and both orbit the common center of mass every 3.42 days. Recent measurements indicate that the binary star system has an age of several billion years, comparable to our solar system.

During this time independent research revealed this star was in fact a binary star - a system comprised of two stars located some 300 light-years from earth. This discovery shed new light on the data being analysed and led to the conclusion that the two stars were billions of years old, not several hundred million as initially suspected, and that the dust surrounding the system was a result of the collision.
