Encyclopedia
Trumpler 10 is an open cluster
located in the constellation
Vela
. It was possibly discovered by Nicolas Louis de Lacaille
in 1751-52, as the cluster's location data matches well with No. II.6 in his catalog. The cluster was also officially discovered by James Dunlop in 1826 and rediscovered independently by R.J. Trumpler in 1903.
A photometric investigation was performed in 1962 which studied 29 stars within the cluster and determined 19 additional possible members. In the study, a minimum age of 3*107 years and a distance of 420 parsec
s were derived.
Open cluster
An open cluster is a group of up to a few thousand stars that were formed from the same giant molecular cloud and have roughly the same age. More than 1,100 open clusters have been discovered within the Milky Way Galaxy, and many more are thought to exist...
