Meteoroid lands in Stirling area

A meteor seen streaking through the sky last week is believed to have
landed somewhere in the Stirling area.

 

Peter Brown, a professor in the University of Western Ontario's
Department of Physics and Astronomy and part of the meteor physics
group, confirmed that the big boom and bright light seen in the sky
Sunday afternoon was, in fact, a meteoroid.

The event was caught on several dashboard cameras, Brown said, and air
waves and radar data collected by his team are all on par with meteoroid
activity.

Brown believes the meteoroid, coming into the atmosphere at a rate of
anywhere from 11 to 73 kilometres per second, first appeared in the
skies of east central Ontario late Sunday.

Following its path, Brown thinks it may have landed somewhere in the
Quinte West-Stirling area.

But that's if the meteoroid survived.

Graham Wilson, a consulting geologist based in Campbellford, said it's
possible the meteoroid splintered into dust particles well before it
touched the earth's surface.

Wilson will be involved in the hunt for Sunday's space rock, but
cautioned that he has to first determine if the meteoroid has become a
meteorite.

Most people mistake meteors for meteorites, Wilson explained.

A meteor is something that's often referred to as a shooting star.

That, Wilson said, is just a speck of dust, often no larger than a
pebble, burning up in the sky.

They are small, Wilson said, but give off fantastic amounts of energy
when they burn up 150 kilometres above the earth's surface.

A meteoroid is something falling through the atmosphere toward the
earth. It becomes a meteorite when it lands on earth, and those can be
the size of a pea to something that weighs several tons.

Assuming that something has landed on earth, the meteorite would be a
charred-black colour, weigh more than a normal rock and likely have a
magnetic pull to it.

The inside of a meteorite looks a lot like grey cement, Wilson
explained, with flecks of shiny metal throughout.

They aren't hot. Wilson pointed out that most people are able to spot
meteoroids when they're 30 kilometres above ground, a height more than
times greater than Mount Everest.

It's cold up there. Wilson said the meteoroid's temperature plummets as
it falls. It also slows dramatically, dropping to speeds of about 100
km/h.
