NGC 1513 is anopen cluster of stars in the northernconstellation ofPerseus, positioned 2° SSE of the faint starLambda Persei. The same telescope field contains the clustersNGC 1528 andNGC 1545.[2] NGC 1513 was discovered in 1790 by the German-British astronomerWilliam Herschel.[3] The brightest component star is of magnitude 11, so a medium-sized amateur telescope is needed to observe 20-30 members. With a 12 in (30 cm)aperture telescope, most of the member stars can be resolved.[7] This cluster is located at a distance of 4,824light-years from the Sun, but is drawing closer with aradial velocity of −14.7 km/s.[1]
This cluster has a rating of II2m in theTrumpler Catalogue, indicating it is moderately rich in stars with little central concentration.[8] It is partially obscured by dust from the Persei dark cloud complex.[2] NGC 1513 is 363 million years old and at least 433 stars in the field are members with a minimum 50% probability. The cluster has acore radius of 4.83 ± 0.55 ly (1.48 ± 0.17 pc) and atidal radius of 65 ± 10 ly (20 ± 3 pc).[5] It has ametallicity of [M/H] =−0.10±0.10 dex, indicating a lower abundance of elements more massive than helium compared to the Sun.[9]
