'2012
DA14' makes history above, but did you see it?
ON Friday, 15 February
2013, an asteroid called:- '2012 DA14' made
history and oddly, only a day earlier, a large fireball was
reported over Japan and just hour before '2012 DA14'
was to make its pass on Friday, a meteorite crashed to Earth
in Russia! Due to the world wide news coverage of the Russian
meteorite impact, National Aeronautics and Space Administration
(NASA), European Space Agency (ESA) and The Russian Federal
Space Agency (Roscosmos or FKA (ФКА)), all issued reassurances
to the public that they could confirm that '2012 DA14'
would not collide with the Earth, and did not pose any risk.
Thankfully '2012 DA14', which is the size of an
Olympic swimming pool and an estimated 130,000 metric tons,
zipped past harmlessly within 28000km of Earth, that's around a
10th the distance to the Moon. If it had struck the Earth, it
would have produced the equivalent of 2.4 megatons of TNT! The
only danger it did pose was to some geosynchronous weather and
communications satellites that orbit Earth. The massive space
rock was not visible to the naked eye, but could just be seen
with a normal pair of binoculars, or an amateur telescope. Cloud
permitting, you could just make it out as it moved across the
heavens.
"Sadly, we did try to
photograph the passing of '2012 DA14', but the clouds and mist
were a problem and we gave up, opting to look at it via
binoculars. This was a photograph we took of the Plough (or for
our friends in the US, the Big Dipper), on the night, just an
hour before it passed across the handle, just to show how
tantalising it was. The other shot we think might be it, with
the Plough behind, but we are not positive it is. Let us know
what you think please..." our editor Patrick Trollope
said. For now, the orbit of 2012 DA14 is such that it will not
crash into Earth for the foreseeable future. It rates 0 (No
Hazard) on the Torino scale. The next closest visitor, we know
about, and will be on a close orbit and of an extremely large
size, will be Apophis. This huge asteroid will pass near Earth
in 2029 and 2036. Don't rush to the bookies mind you, as it has
just a very slim chance of hitting the Earth during its close
flyby in April 2029, so don't worry! Mind you it will be on
Friday the 13th! Apophis, we are reliably informed, was the name
of an evil, ancient Egyptian, monster snake god, so there you
have it. If you did get a glimpse of '2012 DA14',
