}}{{Starbox end}}W Andromedae is a variable star in the constellation of Andromeda. It is classified as a Mira variable of S-type star,[2] and varies from an apparent visual magnitude of 14.6 at minimum brightness to a magnitude of 6.7 at maximum brightness, with a period of approximately 397.3 days.[3] The star is losing mass due to stellar winds at a rate of 2.79{{e|-7}} {{solar mass|link=yes}}/yr.[10]References1. ^1 {{cite DR2}}
