Open star cluster Messier 34 (M34, NGC 1039) is an intermediate aged open cluster of about 100 stars (according to H.S. Hogg), and lies about 1,400 light years and is scattered over 35 arc minutes, more than the diameter of the full Moon. This angular diameter corresponds to a linear 14 light years; Wallenquist has estimated a little more (42' corresponding to 18.5 light years).
