Given the question: Information: - Mira B , also known as VZ Ceti , is the companion star to the variable star Mira . 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 . Its orbit around Mira is poorly known ; the most recent estimate listed in the Sixth Orbit Catalog of Visual Binary Stars gives an orbital period of roughly 500 years , with a periastron around the year 2285 . Assuming the distance in the Hipparcos catalog and orbit are correct , Mira A and B are separated by an average of 100 AU . Long - known to be erratically variable itself , its fluctuations seem to be related to its accretion of matter from Mira 's stellar wind , which makes it a symbiotic star . - Cetus is a constellation. Its name refers to Cetus, a sea monster in Greek mythology, although it is often called 'the whale' today. Cetus is located in the region of the sky that contains other water-related constellations such as Aquarius, Pisces, and Eridanus. - Mira , alternatively designated Omicron Ceti ( Ceti, abbreviated Omicron Cet, Cet) is a red giant star estimated to be 200400 light years from the Sun in the constellation of Cetus. What is the relationship between 'mira b' and 'cetus'?
The answer is:
constellation
