Extractions: Asteroid Introduction The future cannot be predicted, but futures can be invented. - Dennis Gabor Asteroids Introduction Asteroids are rocky and metallic objects that orbit the Sun but are too small to be considered planets. They are known as minor planets . Asteroids range in size from Ceres, which has a diameter of about 1000 km, down to the size of pebbles. Sixteen asteroids have a diameter of 240 km or greater. They have been found inside Earth's orbit to beyond Saturn's orbit. Most, however, are contained within a main belt that exists between the orbits of Mars and Jupiter. Some have orbits that cross Earth's path and some have even hit the Earth in times past. One of the best preserved examples is Barringer Meteor Crater near Winslow, Arizona. Asteroids are material left over from the formation of the solar system. One theory suggests that they are the remains of a planet that was destroyed in a massive collision long ago. More likely, asteroids are material that never coalesced into a planet. In fact, if the estimated total mass of all asteroids was gathered into a single object, the object would be less than 1,500 kilometers (932 miles) across less than half the diameter of our Moon.

Extractions: Dr. Donald Yeomans' Leonids Site Lowell Observatory press release, May 20, 2004 Flagstaff, AZ The ongoing search for near-Earth asteroids at Lowell Observatory has yielded another interesting object. Designated 2004 JG6, this asteroid was found in the course of LONEOS (the Lowell Observatory Near-Earth Object Search) on the evening of May 10 by observer Brian Skiff. "I immediately noticed the unusual motion," said Skiff, "so it was certain that it was of more than ordinary interest." He quickly reported it to the Minor Planet Center (MPC) in Cambridge MA, which acts as an international clearinghouse for asteroid and comet discoveries. The MPC then posted it on a Web page for verification by astronomers worldwide. It happened that all the initial follow up observations, however, were obtained by amateur and professional observers in the Southwest US. The additional sky positions measured in the ensuing few days allowed an orbit to be calculated. The official discovery announcement and preliminary orbit were published by the MPC on May 13. This showed that the object was located between Earth and Venus (presently the very bright "evening star" in the western sky). In addition, 2004 JG6 goes around the Sun in just six months, making it the asteroid with the shortest known orbital period. Ordinary asteroids are located between the orbits of Mars and Jupiter, roughly two to four times farther from the Sun than Earth, taking several years to go around the Sun.
Potentially Hazardous Asteroids Potentially Hazardous asteroids (PHAs) are currently defined based on parameters Specifically, all asteroids with an Earth Minimum Orbit Intersection http://neo.jpl.nasa.gov/neo/pha.html
Extractions: Related Websites WHAT IS A PHA? P otentially H azardous A steroids (PHAs) are currently defined based on parameters that measure the asteroid's potential to make threatening close approaches to the Earth. Specifically, all asteroids with an Earth M inimum O rbit I ntersection D istance ( MOID ) of 0.05 AU or less and an absolute magnitude (H) of 22.0 or less are considered PHAs. In other words, asteroids that can't get any closer to the Earth ( i.e. MOID) than 0.05 AU (roughly 7,480,000 km or 4,650,000 mi) or are smaller than about 150 m (500 ft) in diameter ( i.e. H = 22.0 with assumed albedo of 13%) are not considered PHAs. There are currently 722 known PHAs. This ``potential'' to make close Earth approaches does not mean a PHA will impact the Earth. It only means there is a possibility for such a threat. By monitoring these PHAs and updating their orbits as new observations become available, we can better predict the close-approach statistics and thus their Earth-impact threat.

Extractions: Use the keyboard controls described below to maneuver your ship, destroying as many asteroids as you can while avoiding collision with them. Also watch for the flying saucers armed with guided missles. If you warp into hyperspace, your ship will momentarily disappear then reappear on another part of the screen, gradually fading in. During this time the ship is invunerable. Likewise, when your ship is destroyed a new one will appear in the center of the screen. You can still maneuver and fire during this time so if you are in imminent danger, you have a couple of seconds to get out of it.

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. O Lucifer, son of the morning! " ... 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] ... " Satellites sent to Mars in 1976 collected information concerning the geologic nature of Mars, and it's atmosphere. The images from the orbiters mapping sequence made it clear that Mars had experienced nearly unimaginable catastrophic episodes.

Main Asteroid Belt asteroids are primoridal objects left over from the formation of the Solar Most asteroids are rocky bodies that orbit the Sun between Mars and Jupiter http://www.solstation.com/stars/asteroid.htm
Extractions: Asteroids are primoridal objects left over from the formation of the Solar System (see schematic diagram of nomenclature and relationships among asteroids, Edgeworth-Kuiper bodies, and comets and their different subgroups by William K. Hartmann ). While some have suggested that they are the remains of a protoplanet that was destroyed in a massive collision long ago, the prevailing view is that asteroids are leftover rocky matter that never successfully coalesced into a planet. Most planetary astronomers still believe that the planets of the Solar System formed from a nebula of gas and dust that coalesced into a disk of dust grains around the developing Sun . Within the disk, tiny dust grains coagulated into larger and larger bodies called planetesimals, many of which eventually accreted into planets over a period as long as a 100 million years. However, beyond the orbit of Mars , gravitational interference from Jupiter's huge mass prevented protoplanetary bodies from growing larger than about 1,000 km (620 miles).
