Newly-found asteroid to scrape past Earth on Monday

Earth is about to have a close encounter with an asteroid the size of a house on Monday, when a space rock discovered just days ago will zoom over New Zealand at a range closer than some satellites.

But have no fear, NASA insists the asteroid won't hit Earth.

The asteroid 2014 RC will safely buzz past Earth at 4.18am AEST on Monday.

At that time, the asteroid will pass over New Zealand and fly just inside the orbits of the geosynchronous communications and weather satellites orbiting Earth about 36,000 kilometers above the planet's surface, according to a NASA statement.

During its close pass, 2014 RC will be about 34,000 km from Earth's surface.

That's about 10 times closer to the Earth than the moon.

"Asteroid 2014 RC was initially discovered on the night of August 31 by the Catalina Sky Survey near Tucson, Arizona, and independently detected the next night by the Pan-STARRS 1 telescope, located on the summit of Haleakal? on Maui, Hawaii," NASA officials said in a statement.

The asteroid will be very dim when it passes by Earth.

Observers on the ground won't be able to catch sight of it with the naked eye, but, weather permitting, intrepid amateur astronomers should be able to catch a glimpse of the fast-moving space rock through telescopes, according to NASA.

At its closest approach, the 20-metre asteroid will fly about 40,000 km from the center of Earth.

The average radius of the Earth (the distance from the center of the planet to its surface) is about 6,371 km.

The speedy asteroid isn't a threat to satellites orbiting Earth, and the space rock could even give scientists a special opportunity to learn more about asteroids because it will be so close to the planet, according to NASA.

NASA officials have also mapped out 2014 RC's future orbits to see whether the near-Earth object might pose a threat to the planet in the future.

"While 2014 RC will not impact Earth, its orbit will bring it back to our planet's neighborhood in the future," NASA officials said in the same statement.

"The asteroid's future motion will be closely monitored, but no future threatening Earth encounters have been identified."

Scientists have found more than 10,000 near-Earth objects in the solar system.
