The brightest star in the constellation Andromeda and the northeastern star of the Square of Pegasus.
Alpha Andromedae has overall apparent visual magnitude +2.06 and is theoretically visible at all latitudes north of 60°. When seen by the naked eye, it appears as a single star, but is in fact a binary system with two stars in close orbit.
Alpha Andromedae was Delta Pegasi. It's one corner of the asterism "the Great Square of Pegasus".
Enif(epsilon pegasi) is a double star resolvable in small telescopes. they are a 2.39 magnitude supergiant and a 9 magnitude companion.
ALPHERATZ (Alpha Andromedae). Andromeda runs like a string of pearls to the northeast of the Great Square of Pegasus.
It lies in the northwestern corner (0:39:21.8+21:15:1.7, ICRS 2000.0) of Constellation Pisces -- northeast of Algenib (Gamma Pegasi), southeast of Alpheratz (Alpha Andromedae), southwest of Delta Andromedae and Mirach (Beta Andromedae), ...
This galaxy is within half a degree of second magnitude Alpha Andromedae. Because it is very easy to find its location, use NGC 27 to "evaluate" your current sky conditions. If you can see it, carry on looking for even fainter objects.
Now, it is allocated exclusively to Andromeda, and is known as Alpha Andromedae.

Its three brightest stars together with Alpha Andromedae form the large asterism known as the Square of Pegasus.
I added the Saints with the respective Cloths for further reference and the names of the stars, if available. "Alpha And (Alpheratz/Sirrah)" means "the star Alpha Andromedae has the name Alpheratz or Sirrah".
