The orbit of asteroid 2011 AG5 carries it beyond the orbit of Mars and as close to the sun as halfway between Earth and Venus.

Talk about the asteroid was on the agenda during the 49th session of the Scientific and Technical Subcommittee of the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS), held earlier in Vienna.

Due to its current location in the daytime sky, observations of 2011 AG5 cannot be made by Earth-based telescopes, so its orbit has not yet been determined to a level where scientists can confidently project its location decades into the future. But that day is coming.

"In September 2013, we have the opportunity to make additional observations of 2011 AG5 when it comes within 91 million miles (147 million kilometers) of Earth," said Don Yeomans, manager of NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, California.

A dangerous asteroid heading to the Earth was spotted by stargazers three years after it had got onto its current orbit
To avert a new apocalypse - this time set for February 2013 - scientists suggest confronting asteroid 2012 DA14 with either paint, or big guns. The tough part of either scheme is that time has long run out to build a spaceship for any operation.

NASA confirms the 60-meter (197-feet) asteroid, spotted by Spanish stargazers in February, has a good chance of colliding with Earth in eleven months.

The rock's closest approach to the planet is scheduled for February 15, 2013, when the distance between the planet and space wanderer will be under 27,000 km (16,700 miles). This is lower than the geosynchronous orbit kept by the Google Maps satellite.

Comment: SOTT considers it highly unlikely that this asteroid will impact earth. We have had close misses in the past. 28000km is certainly a relatively short distance, it's about 7% of the Earth-Moon distance, but please remember we had had an even closer miss last year at 4% Lunar distance: Close Shave

For the moment it is not possible to predict exactly how this object will act when it gets close to Earth because of the various gravitational and non-gravitational perturbations. So wait and see as usual.

We should be more worried about those things we don't see...

The enormous fireball was seen from Scotland to the south coast of England.
Police forces and astronomy websites have been inundated with sightings after a suspected meteor shot across darkened British skies.

Reports of a "bright light" and an "orange glow" were received by police across Scotland and the north of England at around 9.40pm on Saturday.

The Met Office tweeted: "Hi All, for anyone seeing something in the night sky, we believe it was a meteorite."

A spokesman for Strathclyde Police said the force had been "inundated" with calls about a bright object in the sky across the west of Scotland.

Minutes later, Durham Police received calls from concerned members of public who had seen a "bright light or a fire in the sky" and believed it may have been an incident involving an aircraft.

The American Meteor Society website was inundated with dozens of Britons logging sightings.

Michelle Thornton, from Birmingham, stated it was "the most amazing thing I have seen in the night sky in ages - outstanding :)"

Meteor Lights up the Sky Across England

Thousands of stargazers witnessed a spectacular meteor shower last night.

It lit up the skies across the north of England and was spotted as far south as Peterborough.

Starstruck: The meteor, visible in the top right hand corner of this image as an elongated white streak, was seen in the skies across the north of England and was spotted as far south as Peterborough.
The shower was seen at various locations across England, including Manchester, Derbyshire and the Lake District.

Hundreds of people posted messages on Twitter after witnessing the event unfold. Scores even put their own video footage of the shower on the internet.

The meteor was first spotted at 9.38pm but other sightings were reported until 9.45pm - which backed up speculation on Twitter that there had been more than one meteor.

Some reports suggested there was a large meteor followed by a series of smaller ones.

One Twitter user wrote: 'The Amazing #Meteor looked like a plane from Man Airport but then seems to rise and burn up in front of me near #JodrellBank.'

Fireball seen from southern Norway and Sweden

It is thought many people witnessed the event, as it the fireball was extremely bright and it was followed by a loud bang.

Astronomer Knut Jørgen Røed Ødegaard, who is behind website Bangirommet.no, is asking for any information that people can provide about it.

He would also like information on any meteorites that may have fallen to the ground, advising people to look on frozen lakes where smaller rocks will not have had the power to go through the ice.

The rocks are likely to be almost or completely black and will stand out easily on road surfaces.

Mr Røed Ødegaard tells The Foreigner, "I've received 800 answers with reports of sightings so far, from southern Norway and Sweden.

"We are now better able to pinpoint the probably location of where the many fragments, known as meteorites, landed. These were in Norefjell, southwestern Norway."

Comment: Here is an all-sky camera shot of the fireball:

How Likely Am I To Be Hit By an Asteroid?

A report suggests that there should be 91 deaths every year from asteroid strikes, but what are the chances of that actually happening?

Buy insurance. Tick. Health check. Tick. Drive sensibly. Tick. As a general rule, we humans like to control our lives. But let's face it, all of this caution is a complete waste of time if a huge rock from space has your name on it.

Take the recent 'near-miss' by the poetically-named asteroid 2012 BX34, which was only discovered two days before it sailed past within 40,000 miles (60,000km) of Earth. What if it had been heading straight for us?

A wonderful report from the US National Research Council (NRC) says that on average there should be 91 deaths per year from asteroid strikes - a remarkably precise figure and one that deserves some digging.

Try to think of when you last heard about an asteroid striking the earth. There really aren't that many of them, or at least that many that are noticed or reported in newspapers.

Green Fireball Seen All Over Southeastern Canada

Similar reports were made throughout the northeastern U.S. Wednesday

A video of the meteor taken at 22:12 EST on 28 February 2012 in Dunrobin, Ontario, Canada:


Facebook and Twitter social media sites on the northeast Avalon were busy with reports of an unidentified, green object falling in the sky over Conception Bay South Wednesday night.

"It was turquoise in colour and was rounded on the bottom and tapered to a point on top. It looked big, but it was hard to tell how far away it was. It was moving extremely fast toward the ground," said a Facebook status update from the St. John's area.

"I've read about a couple of natural phenomena now that could explain it ... something called a green fireball and a meteor - which can apparently be blue, white or green," said another one.

Aidan Ulery of Exeter holds several pieces of what are believed to be stony meteorites. He said that, after seeing a giant, green fireball in the sky at about 10:15 Tuesday night, he went in search of an impact site.
A town already known for its encounters with UFOs may have added another out-of-this-world chapter to its history on Tuesday night.

A piece of a meteoric fireball that was seen across the region may have landed on one of the town's streets.

The fireball, caused when debris burns up in the atmosphere, was spotted by numerous people in New England and Canada on Tuesday night, including Aidan Ulery, 32, of Exeter.

Ulery was at a friend's home on Main Street between 10 and 10:30 p.m., when he saw the light.

"I thought it was a spaceship at first, honestly," Ulery said. "It was a 10-foot, green ball that came suddenly down from the sky."

But unlike the others who reported sightings across the region, Ulery swore the object struck nearby on Park Street, and went looking for it. While he didn't find anything Tuesday night, Ulery said he knew something was different.

No one has reported an alien abduction yet ... but the reports on Twitter and Facebook weren't isolated to eastern Newfoundland.

People from many parts of the northeastern U.S. also posted reports on astronomy internet forums all evening claiming they saw a green light in the sky.

Leap Day New Asteroid Will Zoom By Earth

This NASA graphic depicts the orbit of the small asteroid 2012 DS32, which zooms by Earth on Feb. 29, 2012.

A small asteroid about the size of a house will make one cosmic leap by Earth today, just in time for leap day.

The newfound asteroid 2012 DS32 poses no chance of hitting our planet, but will make an evening pass to mark this special day for Earth, NASA scientists said.

"Happy Leap Day! Small asteroid 2012 DS32 will safely pass Earth at 7:36 p.m. EST," astronomers with NASA's Asteroid Watch program wrote in a Twitter post. The Asteroid Watch program is part of the Near Earth Object office at NASA's Jet Propulsion Laboratory in Pasadena, Calif.

The asteroid 2012 DS32 is about 61 feet (about 18.5 meters) across and will still be a good distance away from Earth when it makes its closest approach. At the nearest point, the asteroid will zoom within about 446,000 miles (717,767 kilometers) of the planet, which is slightly less than twice the distance between the Earth and the moon. The average Earth-moon distance is about 238,000 miles (382,900 km).
