BD +20°307 is a close binary star system approximately 300 light-years away in the constellation Aries. The system is surrounded by a dusty ring.The dust that orbits around several hundred main-sequence stars is cold and comes from a Kuiper-belt analogous region. In our solar system the on-going collisions between asteroids generate a tenuous cloud of dust known as the zodiacal light.
