Mira - ο Ceti (omicron Ceti)
Mira, also designated as ο Ceti (omicron Ceti), is a variable and multiple giant star in the constellation of Cetus.
Mira visual magnitude is 3.04. Because of its moderate brightness, Mira should be easily visible from locations with dark skyes, while it can be barely visible, or not visible at all, from skyes affected by light pollution.
The table below summarizes the key facts about Mira:
Celestial coordinates and finder chart of Mira
Mira is situated close to the celestial equator, as such, it is at least partly visible from both hemispheres in certain times of the year. Celestial coordinates for the J2000 equinox as well as galactic coordinates of Mira are provided in the following table:

Digitized Sky Survey image of Mira
The image below is a photograph of Mira from the Digitized Sky Survey 2 (DSS2 - see the credits section) taken in the red channel. The area of sky represented in the image is 0.5x0.5 degrees (30x30 arcmins). The proper motion of Mira is -0.008 arcsec per year in Right Ascension and -0.237 arcsec per year in Declination and the associated displacement for the next 1000 years is represented with the red arrow.
