Earthgrazer: The Great Daylight Fireball of 1972
Explanation: What is that streaking across the sky? A bright earthgrazing meteor. In 1972, an
unusually bright meteor
from space was
witnessed
bouncing off Earth's atmosphere, much like a
skipping stone
can bounce off of a calm lake. The impressive event lasted several seconds, was visible in daylight, and reportedly visible all the way from
Utah
,
USA to
Alberta
,
Canada
.
Pictured above
, the fireball was
photographed
streaking above
Teton mountains
behind
Jackson Lake
,
Wyoming
,
USA
. The
Great Daylight Fireball of 1972
was possibly the size of a small truck, and would likely have created an
impressive airburst
were it to have
struck Earth
more directly.
Earthgrazing meteors
are rare but are more commonly
seen
when the
radiant
of a
meteor shower
is just rising or setting. At that time, meteors closer to the Earth than
earthgrazers
would more usually strike the Earth near the horizon, while meteors further than
earthgrazers
would miss the Earth entirely. digg_url = 'http://apod.nasa.gov/apod/ap090302.html'; digg_skin = 'compact';
