NGC 225 is an open cluster in the constellation Cassiopeia. It is located roughly 2,200 light-years from Earth. It is about 100 to 150 million years old.[3]
The binary fraction, or the fraction of stars that are multiple stars, is 0.52.[3]
At the 2022 Eldorado Star Party amateur astronomer Will Young, a member of the Astronomical Society of South East Texas, dubbed this open cluster to feature the “Halloween Cat” asterism. A subgroup of brighter stars in this cluster appear to delineate a cat with forward facing eyes, arched back, and raised tail.
