http://www.space.com/scienceastronomy/astronomy/asteroid_paine_august.html

Extractions: Thirtyyears ago, when the Apollo astronauts brought rocks back from the Moon,nobody rushed to stake a mining claim. Only traces of useful materialswere found. The surface of the Moon turned out to be barren and unattractivefor commercial development. Asteroids, however, are anothermatter. Nearly all the raw materials needed to build a self-sufficientspace colony are available on the most common type of asteroid. NASA plansto land a small robotic spacecraft on an asteroid within a few years, justone example of the belief that asteroids are both accessible and worthexploring. Most asteroids are made fromthe raw ingredients of the solar system, researchers believe. Those ingredientscame from supernova exploding overweight stars. The solidified debrisfrom these explosions contains mainly dust, rocks, water ice and iron (actuallyan alloy of iron, nickel and cobalt a natural stainless steel). Nearly5 billion years ago, under the tug of gravity, debris from supernovas gatheredinto a spinning disk. Most of this material fell into the center of thedisk and formed our Sun. Further out the material formed many planets.As these planets circled the Sun they collided with each other and grewlarger, until just nine planets were left. The debris from these collisions,together with other leftover rubble, was either swallowed up in furthercollisions or was mostly herded into planet-free zones like the asteroidbelt between Mars and Jupiter.

IOTA Asteroidal Predictions
International Occultation Timing Association. Listed in the table below arethis quarter s asteroidal predictions. The table is self explanatory.
http://www.lunar-occultations.com/iota/asteroids/astrndx.htm

Extractions: 2005 IOTA Asteroidal Predictions for the Western Hemisphere Notes on Upcoming Events (D. Dunham - External Link) Listed in the table below are this quarter's asteroidal predictions. The table is self explanatory. Clicking on the appropriate link will provide the user with the pertinent information concerning the event. Preliminary paths are given as a general description of path track. As predictions and path maps become available, they will be added to the table. Predictions come from Steve Preston's site. Last minute notes on upcoming asteroidal events, from David Dunham, can by found on the link at the top of the page. Also note: 1) This table contains only those predictions that have Goffin Charts available. There are many more fainter asteroidals where there is no Goffin chart. Those are listed on Steve Preston's website (see link below); and 2) that any archiving of past events have been removed from this site. If you need information on past events, please contact Steve Preston, who is now maintaining the archival information. Regarding the difference between "IOTA observable" events, and the extended Goffin list - With the advent of video recording of occultations, many fainter events and those missed in the Goffin listings, extends the range to record events. Differentiating between observable and non-observable becomes a fine line. It is up to the individual with the equipment available, and information provided by Steve Preston and David Dunham, on whether or not the event will be worth the effort. Therefore, as previously marked in past listings here, the use of color coding of events is dropped.
Asteroids - Video Game Reviews: The Cincinnati Enquirer
1.5/5 Review by James Bottorff with screen shots. While the new version is fun in small doses, it falls short of capturing the addictive enjoyment found in the original.
http://www.cincinnati.com/freetime/games/reviews/asteroids.html

Extractions: The Cincinnati Enquirer Asteroids first invaded arcades some 20 years ago. The game became an instant hit, not because it was a life-changing experience, but because there was little else to plug quarters into. Now, in attempt to ride the recent wave of hurling space object mania, Activision has reinvented the arcade classic for a new generation of game players. How do you update a classic? For starters, incorporate a story line. No you wont find Bruce Willis as a renegade meteor fighter or Morgan Freeman as a president facing the end of the world. What you will find is a story of futuristic mining grounds threatened by space debris. Your job is to clear the mess in order to provide safe passage for both military and civilian spacecraft. While the story fills two pages of the manual quite nicely, it does little to add to the games premise, which remains faithful to the original.
ASTEROIDS, The Classic Game.
Use the keyboard controls described below to maneuver your ship, destroying asmany asteroids as you can while avoiding collision with them.
http://www.webontario.com/asteroids/

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. Controls S Start Game P Pause Game Cursor Left Rotate Left Cursor Down Reverse Thrust Cursor Right Rotate Right Cursor Up Forward Thrust Spacebar Fire Cannon H Hyperspace M Toggle Sound D Toggle Graphics Detail Note: You may have to click on the black screen before the game will start. If the game appears to run slowly on your machine, try turning sound and/or graphics detail off. This will not affect game play.

Asteroids: Debris Of The Solar System
asteroids are the leftovers of the rocks and ice which made the planets.
http://starryskies.com/solar_system/Asteroids/asteroids_top.html

Extractions: When the Solar System formed, not everything was used to make planets and moons, leftovers became asteroids and comets. They are perhaps the oldest remnants of the early Solar System and what we learn from them tells us about our own early history. Most of the asteroids lie between the orbits of Mars and Jupiter, but some have very elliptical orbits which bring them very close to Earth. They range in size from about 30% the diameter of our moon to pebble sized objects. In number, there are probably billion of asteroids in the solar system. The largest known asteroid is Ceres which was the first asteroid to be discovered in 1801. Ceres is about 1/3 the size of our moon. It can be seen in amateur telescopes if one knows where and when to look. Most asteroids are of the small irregular variety. None of them are large enough to have high enough gravity to pull themselves into spherical shape. Images of the same asteroid vary in brightness which confirms the irregular shape. The Galileo spacecraft passed through the asteroid belt twice on its way to Jupiter. The spacecraft passed only 16.000 km from the asteroid Gaspra in 1990 and returned excellent images. Gaspra is an oblong world measuring 20 by 12 by 11 km. It is covered by a layer of shattered soil about a meter deep. There are also numerous craters on Gaspra's surface.

http://www.bbc.co.uk/science/space/solarsystem/asteroids/index.shtml

Extractions: Asteroids range in size from tiny dust particles to huge worlds nearly 1,000 km (600 miles) across. Most asteroids are oddly shaped. They aren't spherical like planets, because their gravity is too low to pull them into a round form. (This only happens when asteroids are over 250 km in size.) Smaller ones are angular and shaped like potatoes and peanuts. The oddest looking asteroid so far is called 'Kleopatra', which looks like a 220km long dog bone.

http://www.astronomynotes.com/solfluf/s2.htm

Extractions: This material (including images) is . See my for fair use practices. There are thousands, even millions, of small rocks that orbit the Sun, most of them between the orbits of Mars and Jupiter. A plot of the known asteroids is available at the Minor Planet Center. About one million of them are larger than 1 kilometer across. Those smaller than about 300 kilometers across have irregular shapes because their internal gravity is not strong enough to compress the rock into a spherical shape. The largest asteroid is Ceres with a diameter of 1000 kilometers. Pallas and Vesta have diameters of about 500 kilometers and about 15 others have diameters larger than 250 kilometers. The number of asteroids shoots up with decreasing size. The combined mass of all of the asteroids is less than the Moon's mass. Very likely the asteroids are pieces that would have formed a planet if Jupiter's strong gravity had not stirred up the material between Mars and Jupiter. The rocky chunks collided at speeds too high to stick together and grow into a planet. Though there are over a million asteroids, the volume of space they inhabit is very large, so they are far apart from one another. Unlike the movie
Our Solar System
An overview of the sun, the nine planets, asteroids, comets, and other links.
http://www.geocities.com/zinazora/solarsystem/index.htm

Extractions: Some scientists think the Solar System began as a cloud of dust and gas. Gravity pulled the cloud in and out, making it smaller and dense (thicker). As it shrank, the cloud heated up and the Sun formed. Some of the clouds flattened out and shaped into a disc, which spun around the new Sun. Particles of gas and dust within the disc bumped each other, which made them stick together and form large lumps. These lumps grew into planets, all of them revolving around the Sun. One group of rocky lumps never grew into planets and these are what we call "asteroids". All information and pictures are courtesy of NASA.

http://www.edunet.ie/stlaur/belt.html

Extractions: The asteroid belt lies between the orbits of Mars and Jupiter. There are so many that they are divided into different groups such as the Trojan asteroids which are 60 degrees in front of and behind the orbit of Jupiter. Other groups of asteroids include the Amor asteroids which cut across the orbit of Mars and the Apollo asteroids that cut across the orbit of the Earth and are probably to blame for the asteroid craters on earth and in the future they might be a source of metals and other minerals for us to mine in space. Some of the asteroids which are close to the earth were photographed and investigated by the space craft Galileo when it was on it's way to Jupiter. It took the first ever close up pictures of an asteroid and showed that the asteroid 951 Gaspa was covered in craters and had a layer of loose fragmentscovering it.
