Huge Impact Crater on Greenland

An iron asteroid believed to have been 3,300 feet in diameter crashed into Greenland leaving a crater 19 miles wide. The estimate of the event is between 12,000 years to 3 million years ago.

A giant meteor crater five times the size of Paris has been found half a mile (0.8 km) under the ice in Greenland.

It is one of the largest impact craters on Earth, and suggests a 3,300ft-wide (1,000-metre) object made of iron smashed into our planet during the last Ice Age.

It is believed the resulting explosion threw debris several hundred miles in every direction, reaching as far as modern day Canada.

The 12-billion-tonne meteor landed with the power of 47 million Hiroshima bombs, obliterating all life within a 60-mile (100 km) radius, scientists said.

A 19-mile-wide (30 km) impact crater left by the event remained hidden for at least 12,000 years beneath the Hiawatha Glacier in remote north-west Greenland, although scientists have not categorically dated the event. It could be as long ago as three million years when Greenland's ice sheet had already begun to form.
