14789 GAISh, provisional designation 1969 TY1, is a dark background asteroid from the outer regions of the asteroid belt, approximately 15 kilometers (9 miles) in diameter. It was discovered on 8 October 1969, by Soviet astronomer Lyudmila Chernykh of the Crimean Astrophysical Observatory at Nauchnij, on the Crimean peninsula.[1] The assumed C-type asteroid has a rotation period of 8.1 hours and possibly an elongated shape.[3] It was named for the Russian Sternberg Astronomical Institute (GAISh) of Moscow State University.[1]
