429 Lotis is a large Main belt asteroid. It is classified as a probable C-type asteroid and is likely composed of primitive carbonaceous materials. This object was discovered by Auguste Charlois on November 23, 1897 in Nice.

In 2002, the asteroid was detected by radar from the Arecibo Observatory at a distance of 1.31 AU. The resulting data yielded an effective diameter of 70 ± 10 km.^[2]
