It was announced on October 7, 2002, and appeared later that day on the JPL current risk page.Due to the proximity of its orbit to Earth and its estimated size, this object has been classified as a potentially hazardous asteroid (PHA) by the Minor Planet Center in Cambridge, Massachusetts. In November 2006 there were 823 PHAs known. As of October 2011, there are 1261 PHAs known. 2002 TD66 was removed from the Sentry Risk Table on October 10, 2002. A Doppler observation has helped produce a well known trajectory with a condition code (Uncertainty Parameter U) of 0.Based on an absolute magnitude (H) of 20.2, the asteroid is estimated to be between 270 and 590 meters in diameter. Radar astronomy shows it is a contact binary asteroid with a diameter of 300 meters and a rotation period of 9.5 hours.On February 26, 2008, 2002 TD66 passed 0.04282 AU (6,406,000 km; 3,980,000 mi) from the Earth. The asteroid also comes close to Venus, Mars, and dwarf planet Ceres.. }
