BD +20 307
Encyclopedia : B : BD : BD2 : BD +20 307
BD +20 307 is a young star, slightly more massive than the Sun, and is located about 300 light-years away in the constellation Aries. It also has a dust cloud orbiting it, like other stars, except for the fact that its temperature is over 100 kelvins and is made up of extremely tiny particles. Conjecture is that around 1000 years ago, these particles were formed by collisions between bodies that were at least as big as the largest asteroids in the Solar System. This explains why the majority of these particles have not been pushed out by stellar winds or spiraled into BD +20 307 yet.
