2102 Tantalus (1975 YA) is an Apollo asteroid discovered on December 27, 1975 by C. Kowal at Palomar Observatory.[1] It is a Q-type asteroid.[1]

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).[1] Its orbit is well-determined for the next several hundred years.

It will pass 0.04439 AU (6,641,000 km; 4,126,000 mi) from Earth on 2038-Dec-27, which is just slightly closer than the 1975-Dec-26 approach of 0.046 AU.[1] The asteroid is about 2–4 km in diameter.[2]
