An image of the 2012 DA14 asteroid shows its approach to Earth, as it was seen yesterday, at 465,000 miles (728,000 kilometers).
The image was created by observations from the Faulkes Telescope South in Siding Springs, Australia.
- The asteroid 2012 DA14 is approximately 150 feet (45 meters) in diameter
- There is no chance the asteroid will collide with the Earth, yet it will be passing closer than ever before
- It will be 7.30pm (GMT) tonight at the time of its closest approach
- At this time, it will be over the eastern Indian Ocean, off Sumatra
- It will be 17,200 miles from Earth at the time of passing, the close approach distance is one tenth the distance between the Earth and moon
Scientists will use a radar to study the 2012 DA14 asteroid, as it flies past the Earth tonight, to learn about its structure and composition.
They hope to use the information to help them plan in the event of another incoming space rock.

Scientists are looking at ways to 'nudge' an asteroid if it was a threat to Earth, as blowing it up would only result in debris falling to Earth, they said.
Tonight an asteroid will approach Earth, passing closer than ever before.
Scientists have said it will be possible to see the asteroid as it flies past the Earth tonight.
It will appear as a faint dot of light, moving at a "steady rate" between the stars.
An asteroid will fly past the Earth tonight, entering the orbit of telecommunication and weather satellites.
This image shows the asteroid's movements, looking down from above Earth's north pole.
This image shows why the asteroid will not be visible to the northern hemisphere's observers, until very close to the Earth, because it is approaching from "underneath" the planet.
An asteroid big enough to destroy London will narrowly miss the Earth as it flies past tonight, according to NASA.
The 150ft-wide rock has no chance of hitting the Earth scientists say, but it will enter the orbits of more than 100 telecommunication and weather satellites, just over 17,000 miles away from the planet.
It is thought it will reach its nearest point to Earth at 7.30pm (GMT) tonight.
The asteroid, 2012 DA14, was discovered by a spanish observatory a year ago.
