Messier 34 (also known as M 34 or NGC 1039) is an w:open cluster in the w:constellation Perseus. It was discovered by w:Giovanni Batista Hodierna before w:1654 and included by w:Charles Messier in his catalog of w:comet-like objects in w:1764.
M34 is at a distance of about 1,400 w:light-years away from w:Earth and consists of some 100 w:stars. It spans about 35' on the sky which translates to a true radius of 7 w:light years. The cluster is just visible to the naked eye in very dark conditions, well away from city lights. It is well seen in w:binoculars.
