House-sized asteroid will pass by Earth at just above satellite altitude

Nasa says there will be 'no danger' when the asteroid 2012 TC4 shaves past Earth at just above the altitude at which most satellites operate on Thursday

A house-size asteroid will give Earth a near-miss on Thursday, giving experts a rare chance to rehearse for a real-life strike threat as it passes inside the moon's orbit.

Dubbed 2012 TC4, the space rock will shave past at an altitude of less than 44,000km (27,300 miles) - just above the 36,000km altitude at which hundreds of geosynchronous satellites orbit the Earth.
