2,800 light-years away from earth. The only Messier object in the constellation Gemini, Messier 35 (M35), also called NGC 2168 or the Shoe Buckle Cluster, is a relatively young open cluster of stars about 150 million years old. Open clusters are groupings of stars that are loosely gravitationally bound. They tend to form from the same cloud of gas and dust, so their stars share characteristics like age and chemical composition, which can be helpful for studying how stars form and evolve.
