Object Description

This small and rather inconspicuous open star cluster was discovered by Charles Messier in July 1764. It is located in an area of the Milky Way with high levels of dust, which causes a darkening of around 3 magnitudes. W. A. Hiltner found out in 1954 that the density of the dust within the cluster was about a factor of 1000 above the galactic mean. The brightest members are all B-type stars. The stellar population resembles the much closer cluster M 36 in Auriga. [4]

The removal of M 29 is described in the «Catalogue of Open Cluster Data (COCD)», Kharchenko et al. 2005 [257] with 1148 pc (3744 ly) and the age with logt = 7.12 (107.12 ≈ 13 million years). Similar values are found in WEBDA [138].
