NGC 146
# NGC 146

NGC 146 is a small open cluster in the constellation Cassiopeia. It was discovered by John Herschel in 1829 using his father's 18.7 inch reflecting telescope.

## Location

NGC 146 is fairly easy to locate in the sky, being half a degree away from the bright star Kappa Cassiopeiae. However, spotting the cluster itself is difficult because of its low apparent magnitude of 9.1. Its relatively high declination of about 63° means it is not visible for below 27° S. Its distance is estimated at about 3030 parsecs (9880 light years ), but may be around 3500 pc (11000 ly) away.

## Characteristics

The cluster is at most 10 million years old, as there are numerous B-type main sequence stars and pre-main-sequence stars but relatively few evolved supergiants. Among its most massive stars are two Herbig Be stars.
