2031 BAM, provisional designation 1969 TG2, is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 8 kilometers in diameter. It was discovered on 8 October 1969, by Soviet astronomer Lyudmila Chernykh at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[8] The asteroid was named for those who built the Baikal–Amur Mainline (BAM; БАМ), a Siberian railway line.[2]
