MESSIER OBJECT 35 - An open cluster approximately 2,800 light years distant in the direction of the constellation Gemini.  About 150 million years old it is a fairly young cluster as indicated by the blue color of the brightest stars. Its total population includes about 2,500 stars occupying an area nearly 30 light years in diameter. 

M35 is an easy find in binoculars or a small telescope near the foot of the twin, Castor.
