Kappa Cassiopeiae


Kappa Cassiopeiae (κ Cas, κ Cassiopeiae) is a star in the constellation Cassiopeia.
κ Cassiopeiae is a blue-white B-type supergiant with a mean apparent magnitude of +4.17. It is approximately 4000 light years from Earth.〔 It is classified as an Alpha Cygni type variable star and its brightness varies from magnitude +4.22 to +4.30.
It is a runaway star, moving at around 2.5 million mph relative to its neighbors (1,100 kilometers per second). Its magnetic field and wind of particles creates a visible bow shock 4 light-years ahead of it, colliding with the diffuse, and usually invisible, interstellar gas and dust. This is about the same distance that we are from Proxima Centauri, the nearest star to the sun. 〔http://www.nasa.gov/jpl/spitzer/bow-shock-wave-20140220/#.Uwd-BVNfQpQ〕
