1135 Colchis, provisionally designated 1929 TA, is a main-belt asteroid discovered by Russian astronomer Grigory Neujmin at the Crimean Simeiz Observatory on 3 October 1929. The X-type asteroid measures about 51 kilometers in diameter and has an orbital period of 4.35 years. Its perihelion is at 2.35 AU^[1]

It was named for the ancient Kingdom of Colchis, bordering on Black Sea south of the Caucasus mountains, in what is now part of Georgia.^[2]
