A blue-white B-type star, Alpheratz is the leading light of Andromeda, holding the Alpha designation, and its near-neutral colour index of −0.038 marks the transition between the hottest blue stars and the white A class. It lies about 97 light-years away and shines at apparent magnitude 2.07. With an absolute magnitude of −0.30, its intrinsic brightness modestly exceeds that of typical white and blue-white stars, and the small difference between its apparent and absolute figures reflects its moderate distance. Alpheratz anchors one corner of the star pattern outlining the figure of Andromeda, at the junction where that constellation meets the neighbouring square of Pegasus.
