What is Zeta Ophiuchi?
[[File:Sig12-014.png|200px|thumb|right|Zeta Ophiuchi is the bright blue star in the center. On the left, in red, is its bow shock.]] '''Zeta Ophiuchi''' is the closest [[Stellar classification|O-type]] [[star]] to the [[Sun]] at nearly 400 [[light years]] away.<ref>https://arxiv.org/abs/0708.1752</ref> It is over 8 times wider than the Sun<ref>https://doi.org/10.1046%2Fj.1365-8711.2001.04658.x</ref> 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. == References == {{Reflist}} [[Category:Stars]]
