NGC 457 is an open star cluster located in the constellation Cassiopeia. It is approximately 9,000 light-years away from Earth and contains around 150 stars. The cluster is often referred to as the "Owl Cluster" due to its resemblance to an owl when viewed through a telescope. Discovered by William Herschel in 1782, NGC 457 is notable for its bright stars, including Epsilon Cassiopeiae, which is one of its most prominent members. The cluster spans about 20 light-years across and is best observed in the autumn months, making it a popular target for amateur astronomers.
