Knowledge graph32 AndHR 175HD 3817HIP 3231

Scientific overview

32 Andromedae is a star in the constellation Andromeda (Andromedae), lying about 354.9 light-years from Earth.

Class G. Yellow stars like the Sun. On the main sequence they steadily fuse hydrogen into helium. Such stars have surface temperatures around 5,200–6,000 K and appear yellow to the eye.
