Andromeda, in mythology, is the daughter of Cepheus and Cassiopeia. In astronomy, it is a constellation that is connected to Pegasus - in fact, it looks quite a bit like Pegasus's back legs.

The connecting star is a member of the Great Square of Pegasus - but officially is the brightest member of Andromeda, Alpha Andromedae or Sirrah. Sirrah is one of two stars that belong to two constellations at once.

Andromeda is kind of on the far side (south) of Cepheus and Cassiopeia.

The other cool thing about Andromeda is that it contains the Andromeda Galaxy (see where M31 is marked on the picture? M31 is the Andromeda Galaxy.) It is to the west of Andromeda. Check out the Andromeda in my Fun Astronomy Fact #1!
