a variable star in the constellation of Andromeda. It is classified as a semiregular variable pulsating giant star, and varies from an apparent visual magnitude of 14.5 at minimum brightness to a magnitude of 9.9 at maximum brightness, with a period of approximately 238.3 days.
66 Andromedae is a binary star [3] system in the northern constellation of Andromeda, near the northern border with Perseus.The designation is from the star catalogue of English astronomer John Flamsteed, first published in 1712.
Omicron Andromedae is a multiple star containing at least three components. It may consist of two close pairs in a wider orbit, making a four-star system, [14] although the binarity of the primary star is in doubt. [11] This star system has a peculiar velocity of 34.5 ± 5.9 km/s. [14]
In Chinese astronomy, the stars that make up Andromeda were members of four different constellations that had astrological and mythological significance; a constellation related to Andromeda also exists in Hindu mythology. Andromeda is the location of the radiant for the Andromedids, a weak meteor shower that occurs in November.

NGC 752 (also known as Caldwell 28) is an open cluster in the constellation Andromeda.The cluster was discovered by Caroline Herschel in 1783 and cataloged by her brother William Herschel in 1786, although an object that may have been NGC 752 was described by Giovanni Batista Hodierna before 1654.
