45 metre asteroid to pass Earth within the hour

An asteroid called 2012 DA14 will narrowly miss Earth as it flies past at 7pm tonight.

The 45 metre diameter rock is big enough to destroy London.

It has no chance of hitting, but it will enter the orbit of more than 100 satellites.

It is expected to fly 17,200 miles (27,000 kilometres) above Earth's surface at around 7pm GMT.

The flyby of 2012 DA14 is the closest-ever predicted approach to Earth for an object this large.

Asteroid not linked to Russian meteor

There's speculation that the meteor could be linked to an asteroid that will pass through satellite space later today.

It is believed to be 50 metres wide and capable of wiping out a city the size of London and is expected to miss Earth by a distance of over 17,000 miles but is the closest ever predicted for an object of that size.

Astronomer Nigel Henbest told ITV News the asteroid is not linked to the Russian meteor:


Asteroids could teach us 'how life came to be on Earth'

An asteroid is expected to pass between the Earth and the moon this evening.

Although it will not hit Earth, it could hit one of its surrounding satellites.

Space journalist and Astrophysicist Sarah Cruddas told Daybreak that scientists knew very little about asteroids.

She said studying them can help provide a better understanding as to why we came to be here on the Earth.

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.

Factfile: Asteroid 2012 DA14

  • 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 study asteroid to prevent future threats

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.


'Possible' to see the asteroid between the stars

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.

It'll be thousands of times fainter than Jupiter and 250 times fainter than the stars of the Plough.

The trick will be to find the area in advance and wait for it to come through. You can use the star maps to find exactly the right part of the sky. If you hold your binoculars steady you will see this tiny point of light crawling across your field of view in about seven or eight minutes.

It's not easy, but you will have the thrill of knowing you are seeing a little object in space the size of an office block.

Asteroid will approach from 'underneath' the Earth

An asteroid will fly past the Earth tonight, entering the orbit of telecommunication and weather satellites.

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.

Asteroid to narrowly miss hitting the Earth

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.
