Sekhmet is believed to be an S-type asteroid, and some believe its diameter is approximately 1.4 km.[4][5]
In December 2003, a team of astronomers at Arecibo Observatory announced that the asteroid may have a moon that measures 300 m in diameter and orbits approximately 1.5 km from Sekhmet.[5] This moon is not yet confirmed.
