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.
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. The asteroid is about 2–4 km in diameter.
