Now scientists know that 2010 WC9 makes one revolution around the Sun for of 1.12 years, during which nebesnoe body is approaching the Sun at distance to 0.78 astronomical units, that is, 117 million miles.

The space rock is larger than the estimated size of the Chelyabinsk meteor before the latter hit Earth's atmosphere in 2013.

2010 WC9 is one of almost 10,000 asteroids classified in the Apollo group, which is a class of near-Earth space rocks that cross over our planet's orbit in their trips around the sun.

Retailer Gap apologises for T-shirts with 'incorrect' map of China
The printed map did not include Taiwan , a self-ruled island considered Chinese territory by Beijing, the capital. In a statement the company said, "Gap Inc. respects the sovereignty and territorial integrity of China".

The asteroid is known as the "lost" asteroid because for nearly 8 years after it was last observed scientists couldn't see it in space.

The Asteroid 2010 WC9 will pass very close to our Earth on Tuesday.

Asteroid 2010 WC9 is an Apollo type space rock. Although there is no risk of impact, this is one of the closest approaches of a space rock of that size. It will not be visible to the naked eye but could get bright enough to be tracked by smaller amateur telescopes. When they did, they calculated its orbital trajectory (which they were unable to do previously), ultimately determining that it will pass within about 130,000 miles of Earth - or half the distance between Earth and the Moon.

The asteroid 2010 WC9, affectionately known as "the lost asteroid", at 200 to 400 feet wide, is close in size to a city block wide.

Tuesday night's flyby will be streamed live on Facebook by the Northolt Branch Observatories.

Comparing this "new" object's orbit to ones previous found, the astronomers quickly realized that they had actually rediscovered a lost asteroid - 2010 WG9, which they had first spotted over 7 years ago, on November 30, 2010.

Oil Remains Upbeat as Brent Crude Trades $77.07
Looking at trading volumes, the recent move up has been accompanied by lower volumes. The global benchmark crude traded at a $7.30 premium to July WTI.

Astronomers hope to further observe asteroid 2010 WC9 in order to better refine its orbit. Our display will be updated every five seconds. "We, of course, collect astrometric data while this happens, but the movement of the asteroid will occur every five seconds".
