Asteroid alert: NASA tracks a large rock heading past Earth at 43,500mph – Will it hit?


At the upper end of NASA’s size estimate, the rock is just 32ft (10m) shorter than the Statue of Liberty in New York, US.

At the lower end of NASA’s estimate, the asteroid is comparable to four London double-decker buses lined up in a row.

NASA said: “Space rocks smaller than about 25m – about 82ft – will most likely burn up as they enter the Earth’s atmosphere and cause little or no damage.

“If a rocky meteoroid larger than 25m but smaller than one kilometre – a little more than half-a-mile – were to hit Earth, it would likely cause local damage to the impact area.”

When a much smaller object exploded in the skies over Russia’s Chelyabinsk oblast in 2013, the resulting arblast injure more than 1,000 with shards of glass from blown-out windows.
