Betelgeuse and 61 Ori
Mu Orionis is a star that can be located in the constellation of Orion. The description is based on the spectral class. Mu Orionis's Alternative Names
Mu Orionis (Mu. Ori) is the Bayer Classification for the star. The Bayer Classification was created by Johann Bayer in 1603. The brightest star in the constellation is normally given the Alpha designation, there are exceptions such as Pollux which is Beta Geminorum.

The Id of the star in the Yale Bright Star Catalogue is HR2124. HIP28614 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalog is HD40932. Flamsteed designations are named after the creator, Sir John Flamsteed. Sir John named the stars in the constellation with a number and its Latin name, this star's Flamsteed designation is 61 Orionis. The Flamsteed name can be shortened to 61 Ori. BD number is the number that the star was filed under in the Durchmusterung or Bonner Durchmusterung, a star catalog that was put together by the Bonn Observatory between 1859 to 1903. The star's BD Number is BD+09 1064.
Multiple Star System Yes, one in which there is at least one star in close orbit to another star or two or more stars orbiting a central point.

Betelgeuse
The variation in the brightness of Betelgeuse was first described in 1836 by Sir John Herschel when he published his observations in Astronomy features. From 1836 to 1840, he noticed significant changes in magnitude when Betelgeuse eclipsed Rigel in October 1837 and again in November 1839. A 10-year rest period followed; then in 1849, Herschel observed another short cycle of variability, which reached in 1852. subsequent observers recorded unusually high highs with a range of years, but only small variations from 1957 to 1967. The American Association of Variable Star Observers records (AAVSO) shows a maximum brightness of 0.2 in 1933 and 1942, and a minimum of 1.2, observed in 1927 and 1941. This variability in brightness may explain why Johann Bayer, with the publication of his Uranometry in 1603, designated the alpha star as it probably rivaled the usual bright Rigel (beta). From arctic latitudes, Betelgeuse red color and the highest position in the sky of Rigel meant the Inuit considered brighter, and a local name was Ulluriajjuaq "big star".
