Paris — The
asteroid that smashed into the central Russian city of Chelyabinsk initially
measured 19 metres (61 feet) across, packing the energy of dozens of Hiroshima
bombs, a study said on Wednesday.
Scientists
in the Czech Republic and Canada analysed video and audio footage and fragments
recovered from the dramatic incident on February 15.
They
estimated the asteroid had probably once been part of the same, massive
celestial object as a two-kilometre (1.2-mile) behemoth called 86039 -- a nasty
"geocruiser" first spotted in 1999 that regularly comes close to
Earth's orbit.
On entering
Earth's atmosphere, the asteroid weighed 12,000 tonnes, a mass translating into
the energy equivalent of 500,000 tonnes of TNT, according to the paper in the
journal Nature.
This is
roughly equivalent to between 27 and 41 times the explosive yield of the first
atomic bomb, used on Hiroshima in 1945.
"The
asteroid broke into small pieces between the altitudes of around 45 and 30
kilometres (28 and 18 miles), preventing more serious damage on the
ground," says the study.

"The
total mass of surviving fragments larger than 100 grammes (3.5 ounces) was
lower than expected."
Previous
estimates have put the object at 17 metres (56 feet) across and a mass of
around 10,000 tonnes.
About 1,200
people were hurt by the shockwave, which blew out windows and damaged buildings
across five Russian regions.
According
to an Internet survey published in the US journal Science, 25 people who were
outside at the time said they received sunburns from the ultraviolet light
released by the meteor.
The study
also says the object was a so-called LL chondrite type of rock, which is
believed to constitute a minority in the asteroid belt.
It is of
the same type as the asteroid Itokawa, samples of which were collected by the
Japanese mission Hayabusa.
In a
separate study also published by Nature, a team led by University of Western
Ontario researcher Peter Brown carried out a survey of big airbursts by
meteors.
The number
of big asteroids could be "an order of magnitude" -- tenfold -- higher
than estimated by telescopic observation of the space around Earth, it said.

Age of Gaia?
.... The next
mention of it came from Archangel Michael in the course of a personal reading I
had with him on March 8, 2013. Geoff asked me to ask AAM for confirmation of
this news that Ashira had broken.
“It could
have triggered what you would think of as … the only comparison you would have
would be… another Ice Age.”
“Wow.
You’re kidding,” I responded.
“No,” he
said.

Steve: So
the galactics prevented another Ice Age. That’s what you’re saying, right?
AAM: That
is what I’m saying. … Your star brothers and sisters intervened. That is why it
was not more dramatic and damaging. And they intervened not only on behalf of
the people of Earth and of Russia, but on behalf of Gaia herself.
S: And was
this heavenly body, so to speak, sent here by the dark forces?
AAM: No. It
is just what is moving about. It is part of the movement of energy, of debris, throughout the universe. So no, there was no negative force behind it, not the
way you think of it.
S: Alright,
if the galactics had not been around at this time, for the purposes of
Ascension, would they still have provided this service?
AAM: Yes. .....
