2102 Tantalus (1975 YA) is an Apollo asteroid discovered on 27 December 1975, by C. Kowal at Palomar Observatory. It is a Q-type asteroid.

2102 Tantalus is a potentially hazardous asteroid (PHA) because its minimum orbit intersection distance (MOID) is less than 0.05 AU and its diameter is greater than 150 meters. The Earth-MOID is 0.0439 AU (6,570,000 km; 4,080,000 mi). Its orbit is well-determined for the next several hundred years.
