Record-setting
asteroid to shave
past Earth this month
An
asteroid about half the size of
a football field will zoom past Earth on Feb. 15, closer than the
man-made
satellites that power GPS, says NASA.
"This
is a record-setting
close approach," Don Yeomans of NASA's Near Earth Object Program at JPL
said in a video released by NASA this week. Yeomans, however,
emphasized that
the asteroid, designated 2012DA14, won't hit Earth.
"It
will come interestingly
close, closer than many man-made satellites," he said.
2012DA14
will thread the gap
between low earth orbit, where the International Space Station and many
earth
observation satellites are located and the higher belt of
geosynchronous
satellites, which provide weather data and telecommunications.
At
its closest point, the asteroid
will only be 17,200 miles above our planet's surface.
"The
odds of impact with a
satellite are extremely remote," Yeomans adds. "Almost nothing orbits
where DA14 passes the Earth.
At
50 meters wide, the asteroid is
"neither very large nor very small" and is probably made of stone as
opposed to ice or metal. Yeomans estimates that an asteroid flies past
Earth,
on average, every 40 years, yet actually hits the planet once every
1200 years
or so.
