The asteroid, 2010 TD54, estimated about 7.3 meters wide, coming to within 46,000 km (29,000 miles) of earth. Patrick Wiggins, of Utah, recorded the cosmic missile streaking among the stars using a digital camera attached to his backyard telescope.

“The target was rotating quickly during both sequences which is ‘reflected’ (pun intended) by its rapidly changing brightness.”
- Patrick,University of Utah’s Physics Department in Salt Lake City.

Patrick, who is one of NASA’s volunteer solar system ambassadors, had to keep his Celestron 14-in telescope turning to track the asteroid as it sped at nearly 17.37km a second (11 miles) to an eighth the distance of the Moon from the Earth. You can view a sequence showing the asteroid speeding against the star trails here. It was produced from 23 five -econd exposures shot between 09:01:27 and 09:04:39 UT.

NASA experts had said there was only a one in a million chance of it hitting the Earth and said it would have burned up in a shower of brilliant fireballs if it had done so. Asteroid 2010 TD54 was discovered by automatic monitoring carried out by the Spacewatch II telescope at Kitt Peak Observatory near Tucson, Arizona, part of the NASA-sponsored Catalina Sky Survey.
