OBJECT DESCRIPTION AND IMAGE SESSION

NGC 2482 is an open cluster located in the constellation Puppis (the Stern). It was discovered by the German-British astronomer William Herschel in 1784. NGC 2482 is approximately 1,343 pc (∼4,380 light-years) from the Solar System, and the latest estimates give it an age of 402 million years. The cluster's apparent size is 10 arcminutes, which, given its distance, gives a maximum actual size of about 13 light-years. According to Robert Trumpler's classification of open clusters, this cluster contains between 50 and 100 stars (letter m) with a moderately low concentration (III) and magnitudes spread over a small range (the number 1).
