Characteristics

It is a rich to moderately rich, intermediate-brightness, detached cluster with Trumpler type II2r or II3m.^[5] There are 494 probable member stars within the angular radius of the cluster and 215 within the central part of the cluster.^[7] The tidal radius of the cluster is 6.3 - 8.7 parsecs (21 - 28 light years) and represents the average outer limit of IC 2714, beyond which a star is unlikely to remain gravitationally bound to the cluster core.^[3] The core of the cluster is estimated to be 5.9 light years across.^[7]

The brightest stars of the cluster are of 11th magnitude and the brightest main sequence stars are of late B of A type.^[8] Two blue stragglers have been detected in the cluster,^[9] one variable star and eleven red giants.^[8] The turn-off mass of the cluster is estimated to be at 3.1 M_☉.^[4] The cluster has the same metallicity as the Sun.^[10]
