NGC 1901 is an open star cluster located in the constellation Canis Major. It was discovered by the astronomer John Herschel in 1834. This cluster is relatively young, with an estimated age of about 100 million years, and contains several bright stars that are easily visible through small telescopes. The cluster is situated approximately 4,000 light-years away from Earth. It is part of a larger group of stars that share a common origin, making it an interesting subject for studying stellar formation and evolution. Observations of NGC 1901 contribute to our understanding of the dynamics of open clusters in the Milky Way galaxy.
