50,000 years ago, a huge iron-nickel meteorite, hurtling at about 40,000 miles per hour, struck the rocky plain of Northern Arizona with an explosive force greater than 20 million tons of TNT. The meteorite estimated to have been about 150 feet across and weighing several hundred thousand tons, in less than a few seconds, left a crater 700 feet deep and over 4000 feet across. Large blocks of limestone, some the size of small houses were heaved onto the rim. Flat-lying beds of rock in the crater walls were overturned in fractions of a second and uplifted permanently as much as 150 feet.

This asteroid is of a relatively rare type with an orbital period much faster than that of the Earth. Notice that its orbit crosses the orbit of all 4 of the inner planets (though not obvious here, the orbit is almost in the plane of the ecliptic). On February 22, 1995 (2 1/2 weeks after discovery), this asteroid passed within 7.5 million km of the Earth---a distance only 20 times that of the distance to the Moon.
"The Earth orbits the Sun in a sort of cosmic shooting gallery, subject to impacts from comets and asteroids. It is only fairly recently that we have come to appreciate that these impacts by asteroids and comets (often called Near Earth Objects, or NEOs) pose a significant hazard to life and property. Although the annual probability of the Earth being struck by a large asteroid or comet is extremely small, the consequences of such a collision are so catastrophic that it is prudent to assess the nature of the threat and prepare to deal with it." -[NASA AMES Research Center]-

"On a clear dark evening, if you look up at the stars and are patient, you may be lucky enough to see a brief trail of light dart across the sky - a "shooting star". These objects are the cause of much confusion amongst the casual observer; are they comets like the famous one discovered by Halley ? Are they meteors, popular subject of old disaster movies ? Or are they asteroids, bodies still more mysterious ? In fact, whilst all three have similar origins, they are very different objects. Comets, Asteroids and Meteorites are all examples of "space debris". They are remnants of the material left over from that period of time which saw the formation of the solar system." -[Nigel Bannister]-
"This website addresses the physics of Asteroids, Comets and Meteoroids as well as their unique characteristics and impact on society.""Historically, space has fascinated scientists throughout the centuries. In 1923, scientists realized that millions of other galaxies made up the universe and that the universe covered a vast area larger than previously thought."-[2002 Space Physics ISU - Langstaff Secondary School Independent Study Unit]-

The Bible describes Satan, commonly called Lucifer, as having had a place in heaven. Where in heaven did satan / lucifer dwell, and what happend to this being? Our research suggests satan, or lucifer, dwelt in a literal location in the heavens... which when destroyed left the debris we now see as asteroids and comets.
" ... is Shoemaker- Levy 9 an asteroid or a comet? This is an issue being debated in the journals right now. In the exploded planet hypothesis there is no difference. Asteroids and comets are the same thing, except that comets were thrown out to a greater distance, so by being away from the Sun for the few million years they preserved their volatiles, their dust and gas, whereas asteroids have long since had the dust and gas blown away by solar radiation pressure, because they're so close to the Sun for millions of years. Other than that there is no difference. They're both debris clouds [of an exploded planetary parent body] ... "
