It is 400 light years away from Earth, and has a magnitude of 9.98. It is a Herbig–Haro object- HH objects are bright patches of nebulosity associated with newborn stars. They are formed when narrow jets of partially ionised gas ejected by stars collide with nearby clouds of gas and dust at several hundred kilometers per second.
