Zeta Ophiuchi

Zeta Ophiuchi is the closest O-type star to the Sun at nearly 400 light years away.https://arxiv.org/abs/0708.1752 It is over 8 times wider than the Sunhttps://doi.org/10.1046%2Fj.1365-8711.2001.04658.x and appears to be travelling fast through space. This could be because it was blasted by a supernova explosion. The fast motion of Zeta Ophiuchi created a bow shock, or shaped gas, around it as it travels through space.
