2013 ET
2013 ET is a near-Earth asteroid that was first observed on March 3, 2013,[4] six days before its closest approach to Earth. It is estimated to be around 100 meters (330 feet) wide.[3][5] The orbit of 2001 SY169 has been connected to 2013 ET extending the observation arc to 11 years.
Its closest approach to Earth was 0.0065207 AU (975,480 km; 606,140 mi) on March 9, 2013 at 12:09 UT.[2][6] The asteroid also makes close approaches to Mars and Venus.[2] The asteroid was imaged by Goldstone radar on March 10, 2013.[7]
2013 ET was one of four asteroids that passed in the vicinity of Earth during one week in early March 2013.[8] The other asteroids in this group besides 2013 ET, included 2013 EC, 2013 EC20, and 2013 EN20.[8]
