Notes
Mira, designation Omicron Ceti (ο Ceti, abbreviated Omicron Cet, ο Cet), is a binary star in the constellation Cetus. The system consists of a variable red giant (Mira A) along with a white dwarf companion (Mira B). Mira A is a pulsating variable star and was the first non-supernova variable star discovered, with the possible exception of Algol. It is the prototype of the Mira variables. The system lies at a distance of 300 light-years (92 parsecs). (source: Wikipedia)
