Encounters with Venus and Earth
edit1992 TB makes close approaches to Earth, but often comes many times closer to Venus. Soon after the discovery of the asteroid in 1992, a close approaches of Earth was made. Three years after it was discovered, 1992 TB came 45,720,000 km (0.3056 AU) from Earth.[1] In 2003, (8035) 1992 TB was listed as a potentially hazardous object,[6] but has since been removed. However, 1992 TB is not expected to come within 37,000,000 km (0.25 AU) of Earth in the near future.[1] On the other hand, 1992 TB can come much closer to Venus. Its next Venus encounter was in 29 May 2015, where it came 11,710,000 km (0.0783 AU) from the planet.[5] Its closest approach in the near future will be 7,380,000 km (0.0493 AU).[1]
