An asteroid discovered just weeks ago has become the most threatening object yet detected in space.
A preliminary orbit suggests that 2002 NT7 is on an impact course with Earth on 1 February 2019, although the uncertainties are large.
Astronomers have given the object a rating on the so-called Palermo technical scale of threat of 0.06, making NT7 the first object to be given a positive value.
From its brightness astronomers estimate it is about 2km wide, large enough to cause continent-wide devastation on Earth.
Dr Benny Peiser
Although astronomers are saying the object definitely merits attention, they expect more observations to show it is not on an Earth-intersecting trajectory.
It was first seen on the night of 5 July, picked up by the Linear Observatory's automated sky survey programme in New Mexico.
Since then astronomers worldwide have been paying close attention to it, amassing almost 200 observations in a few weeks.
Dr Benny Peiser, of Liverpool John Moores University in the UK, told BBC News Online that "this asteroid has now become the most threatening object in the short history of asteroid detection".
NT7 circles the Sun every 837 days and travels in a tilted orbit from about the distance of Mars to just within the Earth's orbit.
Potential devastation
Detailed calculations of its orbit suggest many occasions when its projected path through space intersects the Earth's orbit.
Researchers estimate that on 1 February 2019 its impact velocity on the Earth would be 28km a second - enough to wipe out a continent and cause global climate changes.
However, Dr Peiser was keen to point out that future observations could change the situation.
He said: "This unique event should not diminish the fact that additional observations in coming weeks will almost certainly, we hope, eliminate the current threat."
Easily observable
According to astronomers NT7 will be easily observable for the next 18 months or so, meaning there is no risk of losing the object.
Observations made over that period - and the fact that NT7 is bright enough that it is bound to show up in old photographs - mean that astronomers will soon have a very precise orbit for the object.
Dr Donald Yeomans, of Nasa's Jet Propulsion Laboratory in California, told BBC News Online: "The orbit of this object is rather highly inclined to the Earth's orbit so it has been missed because until recently observers were not looking for such objects in that region of space."
Regarding the possibility of an impact, Dr Yeomans said the uncertainties were large.
"The error in our knowledge of where NT7 will be on 1 February 2019 is large, several tens of millions of kms," he said.
Dr Yeomans told BBC News Online that the world would have to get used to finding more objects like NT7 that, on discovery, look threatening, but then become harmless.
"This is because the problem of Near Earth Objects is now being properly addressed," he said.

I say we fire that ex-big brother tw@ at the asteroid. It might be fun.

Yes but we could live in caves, all the scots can hijack cheddar gorge for the duration of the dust cloud.

I think it may be better if it hit nearer the middle east, we would be safe, AND it would probably bring an abrupt halt to their silly bickering.
They'll have a statue of you in Wales, but it'll be covered in sheep and bird droppings within a week, and no-one will care enough to clean it
Sorry
Sorry
You can do a Bruce Willis Stryke...

Damn straight we'll deal with it. Because I'm a genius.

damn, better hope it hits further north then. if liverpool survives, it's not worth letting it hit.
Geezer on the news said if it hit London it would only wipe out everyting as far as Birmingham.
