Astronomy Picture of the Day: Meteor Over Canada

APOD’s November 25th posting features a ‘desk-sized’ meteor which fell to earth over western Canada, illuminating Alberta and British Columbia skies late in the evening of November 20th.

This police dashboard camera captures the meteor in its final moments.  Astronomers hope to attempt to triangulate its position to both determine its impact site, and also discover its origin.  The heavy gravitational field of Mars and Jupiter conventionally pull most all meteors, compets and asteroids away from the earth’s orbit, but on rare occasions, foreign bodies land on our planet.

It is speculated that lake Huron (and possibly the wide spread of lakes spanning Canada’s provinces and territories) could have been created by an earth-killer, explaining why there are so many rare and precious metals and rocks surrounding the Great Canadian Shield.
