What constellation is Mirfak?
Alpha Persei/Constellations
Mirfak, the brightest star in the constellation Perseus, lies high in the east on December evenings. It makes a great companion to the sky’s most celebrated eclipsing binary star, Algol, the Demon Star. The two stars are about 10 degrees, or a fist-width, apart in Perseus.

Perseus is the 24th largest constellation in the sky, occupying an area of 615 square degrees. It is located in the first quadrant of the northern hemisphere (NQ1) and can be seen at latitudes between +90° and -35°.
What type of star is Atik?
Atik is a Giant Star type star. Atik is a B1III giant star based on the spectral type that was recorded in the Hipparcos star catalogue. Atik is not part of the Perseus constellation outline but is within the borders of the constellation. Based on the spectral type (B1III) of the star, the star’s colour is blue .

When did the International Astronomical Union give Mira its name?
In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN’s first bulletin of July 2016 included a table of the first two batches of names approved by the WGSN, which included Mira for this star.
How is the luminosity of the star Mira determined?
In Mira, the highest luminosity occurs close to the time when the star is hottest and smallest. The visual magnitude is determined both by the luminosity and by the proportion of the radiation that occurs at visual wavelengths.
How old is the star Mira according to Bouillaud?
Bouillaud’s measurement may not have been erroneous: Mira is known to vary slightly in period, and may even be slowly changing over time. The star is estimated to be a six-billion-year-old red giant. There is considerable speculation as to whether Mira had been observed prior to Fabricius.
When was the companion star of Mira resolved?
The 10.34 mag bright companion star, which is 118.7 arcseconds away from the main star [1], was resolved by the Hubble Space Telescope in 1995, when it was 70 astronomical units from the primary; and results were announced in 1997.
