NGC 2451 is an open cluster of stars in the Puppis constellation,[1] probably discovered by Giovanni Battista Hodierna before 1654 and John Herschel in 1835.[2] In 1994, it was postulated that this was actually two open clusters that lie along the same line of sight. This was confirmed in 1996. The respective clusters are labeled NGC 2451 A and NGC 2451 B, and they are located at distances of 600 and 1,200 light-years, respectively.[3]
