V385 Andromedae is a variable star in the constellation Andromeda, about 360 parsecs (1,200 ly) away. It is a red giant over a hundred times larger than the sun. It has an apparent magnitude around 6.4, just about visible to the naked eye in ideal conditions.
V385 Andromedae was identified as a long-period variable in 1999 from analysis of Hipparcos photometry.[6] It was classified as a slow irregular variable,[3] but analysis of its light curve identified a possible 36 day period.[2] It varies by about 0.1 magnitudes.[2][3]
