Asteroid 2005 TG50 passes the Earth.

Asteroid 2005 TG50 passed the Earth at a distance of 6 059 000 km (a little under 16 times the distance between the Earth and the Moon) slightly after 11.20 am GMT on Wednesday 13 November 2013. There was no danger of the asteroid hitting us and should it have done so it would have presented little threat. 2005 TG50 is estimated to be between 21 and 65 m in diameter, and an object of this size would be expected to break up in the atmosphere between 22 and 5 km above the ground, with only fragmentary material reaching the Earth's surface.

2005 TG50 was discovered on 11 October 2005 by the Lowell Observatory Near-Earth Object Search. The designation 2005 TG50 implies that it was the 1257th asteroid discovered in the first half of October 2005 (period 2005 T).

2005 TG50 has a 324 day orbital period, which takes in to 0.80 AU from the Sun (90% of the distance at which the Earth orbits the Sun) and out to 1.04 AU (4% further away from the Sun than the Earth). It is classed as an Aten Group Asteroid, a body which spends the majority of its time closer to the Sun than the Earth, but which does pass outside our orbit.

  1. Prodigy plays a important role in Oil and Gas investment. For Oil and Gas investment you should know about prodigy oil and gas investment and its operations. Even though some of Prodigy wells are operated by unaffiliated companies (both public and private) we do house our own operation company (Rock Solid Operations)
