zorroloco 15-Feb-13, 06:56	wait a minute they called it a meteorite, but then say it exploded before it hit the earth... isn't the difference between a meteor and a meteorite that the first does not impact the earth, while the second has to impact the earth to earn the sobriquet 'meteorite?'
zorroloco 15-Feb-13, 06:58	rats! now it appears i used the word 'sobriquet' wrong. i thought it was a name, but apparently it means a nickname. just one of those mornings!
chaz5 15-Feb-13, 07:16	... not too much in that Russian video except some what looked like arching clouds ... is that the "chem-trail" of this meteor(ite)? The driver was going pretty fast.

tjinwa 15-Feb-13, 08:00	Found this so here you go Near Earth Object (NEO) - Near Earth Objects are asteroids or comets that have orbits around the Sun that bring them close to the Earth. The actual definition of an NEO is a comet or asteroid whose orbit brings it close to Earth’s orbit. Asteroid - A relatively small, inactive body, composed of rock, carbon or metal, which is orbiting the Sun. Comet - A relatively small, sometimes active object, which is composed of dirt and ices. Comets are characterised by dust and gas tails when in proximity to the Sun. Far from the Sun it is difficult to distinguish an asteroid from a comet. Meteoroid - A small particle from an asteroid or comet orbiting the Sun. Meteor - A meteoroid that is observed as it burns up in the Earth’s atmosphere – a shooting star. Meteorite - A meteoroid that survives its passage through the Earth’s atmosphere and impacts the Earth’s surface. In summation, an asteroid is a relatively small object out in space. When an asteroid breaks through our atmosphere and burns up, it becomes a meteor. If the asteroid manages to get all the way through our atmosphere and actually hits the surface of the planet, it is classified as a meteorite.

tjinwa 15-Feb-13, 09:37	chaz I have always been curious - Google was invented for me! LOL And, yes, to anyone who wonders, I take everything on the web with a grain of salt and verify. It makes me late to work sometimes though....
