IC 4651 is an
mass of the Sun.[7]
The currently known active stars in this cluster form only about 7% of the cluster's original mass. Of the remainder, about 35% of the mass consists of stars that have evolved into
stellar remnants. The remainder of lost mass consists of stars that have migrated away from the main body of the cluster or have been lost completely.[7]
The star IC 4651 9122 displays radial velocity variations suggesting the presence of a planetary companion, though stellar activity cannot be completely ruled out.[8][9][10]
