Another asteroid is heading past Earth and is being tracked by NASA.
Dubbed a 'near-Earth' asteroid, it will 'safely past by our planet' at a distance of around 1.2million miles away on Tuesday (January 18), the space experts say
It's full name is 7482 (1994 PC1) and is believed to measure 3,551 feet wide - that's bigger than any building on our planet, the Mirror reports.
NASA said: "Near-Earth #asteroid 1994 PC1 (~1 km wide) is very well known and has been studied for decades by our #PlanetaryDefense experts.
"Rest assured, 1994 PC1 will safely fly past our planet 1.2 million miles away next Tues., Jan. 18."
On its website, Nasa's Center for Near Earth Object Studies (CNEOS) says: "Potentially Hazardous Asteroids (PHAs) are currently defined based on parameters that measure the asteroid’s potential to make threatening close approaches to the Earth."
Ways to protect earth from any asteroids that come too close to earth are being examined by NASA, which has launched its Double Asteroid Redirection Test (DART) mission.
Nasa said: "DART is the first-ever mission dedicated to investigating and demonstrating one method of asteroid deflection by changing an asteroid’s motion in space through kinetic impact."
Earlier this week, a massive asteroid - 2013 YD48 - wider than Big Ben passed Earth and was too small to be considered "a potentially hazardous object"
