This binary star system consists of a red giant (Mira, designated Mira A) undergoing mass loss and a high-temperature white dwarf companion (Mira B) that is accreting mass from the primary. Such an arrangement of stars is known as a symbiotic system and this is the closest such symbiotic pair to the Sun .
Mira B, also known as VZ Ceti, is the companion star to the variable star Mira, separated by around 100 AU. Suspected as early as 1918, it was visually confirmed in 1923 by Robert Grant Aitken , and has been observed more or less continually since then, most recently by the Chandra X-Ray Observatory .
Mira, the prototype of the Mira variables. Mira variables / ˈ m aɪ r ə / (named for the prototype star Mira) are a class of pulsating stars characterized by very red colours, pulsation periods longer than 100 days, and amplitudes greater than one magnitude in infrared and 2.5 magnitude at visual wavelengths.

It is a beige-colored, desolate world orbiting a pair of binary stars, and inhabited by human settlers and a variety of other life forms. The planet was first seen in the original 1977 film Star Wars, and has to date featured in a total of seven Star Wars theatrical films, three live-action television series, and four animated series.

Mira, / ˈ m aɪ r ə /, also known as Omicron Ceti (or ο Ceti / ο Cet), is a red giant star estimated 200-400 light years away in the constellation Cetus. Mira is a binary star, consisting of the red giant Mira A along with Mira B.

R Aquarii is a symbiotic star believed to contain a white dwarf and a Mira-type variable in a binary system. The orbital period is approximately 44 years. [ 6 ] The main Mira-type star is a red giant , and varies in brightness by a factor of several hundred and with a period of slightly more than a year; this variability was discovered by Karl ...
