context_page_description: Meissa, designated Lambda Orionis is a star in the constellation of Orion. It is a multiple star approximately 1,100 ly away with a combined apparent magnitude of 3.33. The main components are an O8 giant star and a B-class main sequence star, separated by about 4".
context_section_description: Meissa is surrounded by a ring of nebulosity about 12 degrees across. It is thought to be the remains of a supernova explosion, now ionized by the ultraviolet radiation from Meissa itself and some of the surrounding hot stars.
