Upsilon Pegasi

Upsilon Pegasi, Latinised from υ Pegasi, is a star within the great square in the northern constellation of Pegasus. It has the proper name Alkarab . This object has a yellow-white hue and is faintly visible to the naked eye with an apparent magnitude of 4.40. It is located at a distance of approximately 170 light-years from the Sun based on parallax, but is drifting closer with a radial velocity of −8.6 km/s. The star is moving through the Galaxy at a speed of 50.6 km/s relative to the Sun. Its projected Galactic orbit carries it between 18,600 and 26,300 light-years from the center of the Galaxy.
This object is an aging giant star with a stellar classification of F8III. It is currently in the Hertzsprung gap and is a source of X-ray emission. The star has 2.2 times the mass of the Sun and is spinning with a projected rotational velocity of 73.4 km/s. It has an iron abundance of −0.01 dex, or 97.7% of the Sun's. Upsilon Pegasi has six times the girth of the Sun and is radiating 43 times the Sun's luminosity at an effective temperature of 6,061 K.
Nomenclature.
"υ Pegasi" is the star's Bayer designation. The star bore the traditional Arabic name "Al Karab" ("the Bucket-rope"). In 2016, the IAU organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN approved the name "Alkarab" for this star on 5 September 2017 and it is now so included in the List of IAU-approved Star Names.
