Bellatrix is a hot, luminous blue star and is also an eruptive [[variable star]].<ref name=constellation-guide/> These changes in the star's output are due to violent processes such as [[solar flare]]s.<ref>{{cite web|url=http://www.astro.keele.ac.uk/workx/superwasp-variable-stars/Eruptive.html|title=SuperWASP Observations of Variable Stars|accessdate=2018-12-28}}</ref> It's [[star magnitude|magnitude]] only varies slightly from +1.64 to a peak of +1.59, though since it only varies due eruptive events, it averages out to +1.64.<ref name=constellation-guide/> The star has a [[spectral type]] of B2 III and is one of the hottest stars visible to the naked eye; it has a [[temperature]] of 18,900 [[kelvin]].<ref name=universeguide/> The star used to be used as a standard candle but this stopped after its variable nature was discovered.
