The cluster contains about 200 stars. The brightest of these has an observed brightness of +9.0 and belongs to the spectral type B8. The cluster contains several giant stars. The age is estimated at about 78 million years.
The dimensions of the cluster are approximately 14 x 19 light-years (The central, densest part has a diameter of about 10 light-years).
The cluster was perhaps discovered by Giovanni Domenico Cassini before 1711.
