The asteroid, known as 4660 Nereus, is expected to pass planet Earth just before Christmas on December 11. The 330-meter-long asteroid, which is larger than the Eiffel Tower or the Shard, is expected to travel at speeds of up to four miles per second.
This is about ten times the distance between Earth and the Moon.
Despite this, the US space agency called the rock “potentially dangerous”.
According to the National Aeronautics and Space Administration (NASA) website, a “potentially dangerous” asteroid is at least 150 meters long and is within 4.6 million miles of Earth orbit.

The closest is expected to arrive on Valentine’s Day in 2060, when it is 745,000 miles away.
However, the asteroid was first detected by scientists in 1982.
Space Reference claims that the asteroid orbits the Sun every 664 days.

However, 4660 Nereus is not the first asteroid to come close to Earth this year.
The 1994 asteroid WR12, believed to be roughly double the size of Big Ben, passed Earth 3.8 million miles on November 29.
