As Mira is the brightest periodic variable that is not visible to the naked eye for part of its cycle, when Johannes Hevelius observed it, he named it "Mira" (meaning "wonderful" or "astonishing," in Latin) because it acted like no other known star.

I've found one estimate of the absolute magnitude of Mira: 0.93. However, Mira is a variable star, so perhaps that's an average value. Also, the distance to Mira is not known precisely, so any value for absolute magnitude can only be approximate.
