    1129 Neujmina is a main belt asteroid orbiting the Sun. Approximately 35 kilometers in diameter, it makes a revolution around the Sun once every 5 years. It completes one rotation once every 8 hours. It was discovered by Praskovjya Parchomenko at Simeis on August 8, 1929.[1] It was named for Grigory Nikolaevich Neujmin, an astronomer at the Pulkovo and Simeis Observatories, who discovered seven comets and more than 70 minor planets. Its provisional designation was 1929 PH.[2]

    Photometric observations of this asteroid collected during 2008 show a rotation period of 5.089 ± 0.004 hours with a brightness variation of 0.29 ± 0.02 magnitude.[3]
