1122 Neith is a main belt asteroid, approximately 12 km in diameter, orbiting the Sun. It was discovered by Eugène Joseph Delporte on September 17, 1928, at Uccle and was given the provisional designation 1928 SB. It was named for the Egyptian goddess of Libyan origin, Neith, goddess of the hunt and of war, believed to be the mother of the Sun.[1][2]
Photometric observations during 2008 showed a rotation period of 12.5990 ± 0.0006 hours and a brightness variation of 0.08 ± 0.02 in magnitude.[3]
Measurements made with the IRAS observatory give a diameter of 13.84 ± 1.46 km and a geometric albedo of 0.34 ± 0.07. By comparison, the MIPS photometer on the Spitzer Space Telescope gives a diameter of 13.81 ± 0.73 km and a geometric albedo of 0.34 ± 0.02.[4]
