NGC 2353
NGC 2353: Section from DSS2 [147]


On 10 January 1785 William Herschel sweeped his 18.7 inch reflecting telescope through the constellation Monoceros and found the «coarsely scattered clusters of stars» which he cataloged as VIII 34. He described it as «an extensive cluster of scattered stars». [463] In 1888 John L. E. Dreyer added this cluster as NGC 2353. [313]

Physical Properties

NGC 2353 is a young open cluster, located on the eastern edge of the Canis Majoris OB1 association (CMa OB1). The age of the cluster is estimated to 7.6 million years. The number of member stars is estimated to 65. It is uncertain whether the cluster and CMa OB1 are also physically related. [559, 560]
