Description

This cluster was probably another one discovered by Hodierna. Because of its southern declination, northern observers including Charles Messier and William Herschel could not find it.
NGC 2451 consists of 40 stars, the brightest of which (c Puppis) is a yellowish giant of magnitude 3.6. Its age was estimated at 36 million years, and it is receding from us at 26 km/sec. At only about 850 light years, this cluster is quite close to us. (From Wilkpedia)
