This is an A-type main-sequence star with a stellar classification of A1Vnn,^[3] where the 'n' notation indicates (very) "nebulous" lines due to rapid rotation. However, Gray and Garrison (1987) found a class of A0.5 IVnn,^[9] which would instead match an evolving subgiant star. It is a suspected variable star of unknown type.^[10] This object is 149^[5] million years old with 2.23^[5] times the mass of the Sun and about 2.5^[6] times the Sun's radius. It is radiating 65^[2] times the Sun's luminosity from its photosphere at an effective temperature of 9,972 K.^[5]
