Please visit our sponsor: Asteroids - planetary bricks Sun Mercury Venus Earth ... Mars Asteroids Jupiter Saturn Uranus Neptune ... Kuiper Asteroids are lumps of rock, some as big as 1000 km in diameter, others as small as a computer monitor! Most of them lie in a fairly wide belt orbiting the Sun between Mars and Jupiter , called (surprisingly!) the Asteroid Belt. The word asteroid has a real meaning, much like the word planet . Asteroid means "star like", because the first asteroids that were discovered resembled very dim stars. Fig. 1: Location of the asteroids There are probably over 10,000 asteroids larger than 100 km across in the Solar System, with many millions of smaller ones. Most of these can be found in a belt between the planets Mars and Jupiter The first asteroid was discovered as a result of a curious relatonship known as Bode's Law . This is not a law at all, and is really only a coincidence. It goes as follows: Bode's Law Start with the number series in the first column below... Add to each number... Then divide by S S+4 (S+4)/10 Planet Distance Mercury Venus Earth Mars Jupiter Saturn Uranus Now compare these values with the average distances of the planets ( as known by Bode in 1772 ) from the Sun , measured in AU Top Right ^^ The Hunt Begins Alarmingly, Bode's Law produces numbers that are

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.

11. Asteroids Overview of current scientific knowledge of asteroids. http://www.nineplanets.org/asteroids.html

Asteroids On the first day of January 1801, Giuseppe Piazzi discovered an object which he first thought was a new comet. But after its orbit was better determined it was clear that it was not a comet but more like a small planet. Piazzi named it Ceres, after the Sicilian goddess of grain. Three other small bodies were discovered in the next few years (Pallas, Vesta, and Juno). By the end of the 19th century there were several hundred. Several hundred thousand asteroids have been discovered and given provisional designations so far. Thousands more are discovered each year. There are undoubtedly hundreds of thousands more that are too small to be seen from the Earth . There are 26 known asteroids larger than 200 km in diameter. Our census of the largest ones is now fairly complete: we probably know 99% of the asteroids larger than 100 km in diameter. Of those in the 10 to 100 km range we have cataloged about half. But we know very few of the smaller ones; there are probably considerably more than a million asteroids in the 1 km range. The total mass of all the asteroids is less than that of the Moon 11 comets and asteroids have been explored by spacecraft so far, as follows: ICE flyby of Comet Giacobini-Zinner. Multiple flyby missions to Comet Halley. Giotto (retarget) to Comet Grigg-Skellerup. Galileo flybys of asteroids Gaspra and Ida (and Ida satellite Dactyl). NEAR-Shoemaker flyby of asteroid Mathilde on the way to orbit and land on Eros. DS-1 flybys of asteroid Braille and Comet Borrelly. Stardust flyby of asteroid Annefrank and recent sample collection from Comet Wild 2. For future we can expect: Hayabusa (MUSES-C) to asteroid Itokawa, Rosetta to Comet Churyumov-Gerasmenko, Deep Impact to Comet Tempel 1, and Dawn to orbit asteroids Vesta and Ceres.

14. SmallBodies In The Solar System Overview of asteroids, comets, meteors. Images, data, links. http://www.nineplanets.org/smallbodies.html

Small Bodies The title The Nine Planets is somewhat misleading. In addition to the planets and their satellites the solar system contains a large number of smaller but interesting objects. There are thousands of known asteroids and comets and undoubtedly many more unknown ones. Most asteroids orbit between Mars and Jupiter . A few (e.g. 2060 Chiron) are farther out. There are also some asteroids whose orbits carry them closer to the Sun than the Earth (Aten, Icarus, Hephaistos). Most comets have highly elliptical orbits which spend most of their time in the outer reaches of the solar system with only brief passages close to the Sun. The distinction between comets and asteroids is somewhat controversial . The main distinction seems to be that comets have more volatiles and more elliptical orbits. But there are interesting ambiguous cases such as 2060 Chiron (aka 95 P/Chiron) and 3200 Phaethon and the Kuiper Belt objects which seem to share some aspects of both categories. Asteroids are sometimes also referred to as minor planets or planetoids (not to be confused with "lesser planets" which refers to Mercury and Pluto ). Very small rocks orbiting the

Asteroids Click on image for larger version( 175K GIF Galileo image of Gaspra (29 October 1991) courtesy of NASA/JPL Asteroids are small bodies that are believed to be left over from the beginning of the solar system 4.6 billion years ago. They are rocky objects with round or irregular shapes up to several hundred km across, but most are much smaller. More than 100,000 asteroids lie in a belt between Mars and Jupiter. These asteroids lie in a location in the solar system where there seems to be a jump in the spacing between the planets. Scientists think that this debris may be the remains of an early planet, which broke up early in the solar system. Several thousand of the largest asteroids in this belt have been given names. The chances of an asteroid colliding with Earth are very small! But some do come close to Earth, like Hermes (closest approach of 777,000 km).

20. Chiron And Friends (Centaurs, Asteroids, Exoplanets) Chiron and other Centaurs (Pholus, Nessus) in astrology, astronomy and mythology. Information on asteroids, minor planets and exoplanets by Zane Stein. http://www.geocities.com/SoHo/7969/chiron.htm

© by Zane B. Stein kai -ron ] Chiron's Symbol (has many faces) Chiron is a major key to understanding, not only our solar system (in astronomy), but healing and wholemaking (in astrology.) It was discovered in 1977, and was so different from anything else ever found that a whole new category had to be invented for it. When Chiron was discovered to have company, in the early 1990's, this new category was given a name: The Centaurs. And these other bodies, too, are proving of major significance. First to be discovered was the body they named PHOLUS, next came NESSUS, ASBOLUS, CHARIKLO and HYLONOME. There are several more that have not as yet been named. I do not think that we can get a complete picture of who we are, or how to heal, unless we include these bodies as well. My name is Zane B. Stein, and I began studying Chiron only weeks after its discovery. These are my pages dedicated to Chiron and Friends. I hope that they open doors for you, the way Chiron has for me. CLICK THE DOORWAY TO ENTER CHIRON AND FRIENDS This wonderful Centaur was designed by the fantastic creative talents of my friend Alice Loftin, aka Aliki.
