M35 is an open cluster that can be found in Gemini and is 2,800 ight-Years away.  The mass has been computed using a statistical technique based on proper motion velocities of its stars.


The mass within the central 3.75 parsecs was found to be between 1600 and 3200 solar masses (95 percent confidence), consistent with the mass of a realistic stellar population within the same radius.
