NGC 752 (also known asCaldwell 28) is anopen cluster in the constellationAndromeda. The cluster was discovered byCaroline Herschel in 1783 and cataloged by her brotherWilliam Herschel in 1786, although an object that may have been NGC 752 was described byGiovanni Batista Hodierna before 1654.^[4]

The large cluster lies 1,400light-years away from theEarth and is easily seen through binoculars, although it may approachnaked eye visibility under good observing conditions. A telescope reveals about 60 stars no brighter than 9th magnitude within NGC 752.^[3]^[5]

Components

[edit]

The most up-to-date research lists 302 stars as members of NGC 752.^[2] Since the age of the cluster is1.34±0.06 Gyr, they are mainly low mass stars on themain sequence orred giants, with a main sequence turnoff at about F0. Ablue straggler star is also present, along with somespectroscopic binaries andvariable stars.^[6]^[7] The detachedeclipsing binary DS Andromedae is a member of this cluster.^[8]
