Physical characteristics

In an image taken by the Hubble Space Telescope in 2006 (see picture), astronomers spotted a green planetary nebula towards the bottom of the image. It is uncertain whether NGC 1846 contains this planetary nebula or if it just happened to be on the same line of sight; however, measurements of the motion of the cluster's stars along with the nebula's central star lead to the conclusion that it is a member of the cluster.[3]
