thesun– NASA is keeping an eye on a large asteroid that is set to zip past Earth on Christmas Day.
The space rock 501647 (2014 SD224) is on the US space agency’s “Close Approach” list and could be up to 689 feet wide.
That’s as long as two football pitches.
It’s predicted to come within 1.9million miles of Earth.
This may seem like it’s no risk at all but in terms of space that is pretty close.
Any fast moving space object that comes within around 4.65million miles is considered to be “potentially hazardous” by cautious space organisations.
The space rock is expected to shoot past our planet on December 25.
It should be at its closest at around 8:20pm UK time (3:20pm ET).
According to Nasa’s Close Approach table, a much smaller asteroid called 2020 XY will also fly past much earlier in the day.
This asteroid could be up to 144ft wide but should be much further away.
It’s predicted to shoot past at 3.6million miles from Earth.
The bigger and closer approaching Asteroid 501647 (2014 SD224) is travelling at a speed of around 22,000mph.
Nasa has labelled both asteroids as Near Earth Objects (NEOs).
In other space news, an impressive amount of ‘alien soil’ from a huge asteroid has been revealed by Japan’s space agency.
Britain is to launch a spacecraft next year in a mission to ambush a comet and unlock mysteries of the universe.
And, Nasa has announced its first team of astronauts that will be heading for the Moon.
