Asteroid the size of Space Needle tower heading towards Earth on Christmas Day

A huge asteroid estimated to be the size of the Space Needle tower in Washington is set to collide with Earth's orbit on Christmas Day.

As the world celebrates Christmas, asteroid 501647 will be zooming past planet Earth at 22,300 miles per hour.

It is expected to pass our planet safely but will collide with the Earth's orbit beforehand as NASA have classed it as an Apollo asteroid.

Apollo asteroids are Near Earth Objects that have a greater axis than the rest of the Earth and therefore collide with the planet in orbit.

The asteroid is estimated to be anywhere between 90m and 210m, making it one of the biggest asteroids to pass Earth in December.

To put this into perspective, at its upper limit the asteroid has the potential to be bigger than the Space Needle in Washington, Seattle.

The Space Needle stands at a whopping 184m tall and was designed for the 1962 World's Fair.

Like an asteroid, the Space Needle moves because its engineers equipped the building with a rotating restaurant, at its peak turning at speeds of about 0.053 kph.

Asteroid 501647 will pass planet Earth on December 25, otherwise known as Christmas Day in some countries.

It will zip past just as you’re about to go back for seconds at 8.20pm Eastern Standard Time, equivalent to 01:20am, making it Boxing Day in the UK.

Another asteroid will grace the skies on Boxing Day, 2012 XE133, will pass Earth a whole day after 501647.

It is estimated to be between 56m and 120m wide, making it a lot smaller than the Christmas Day rock.
