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 Asteroids are minor planets, most of which orbit the Sun between Mars and Jupiter. Their orbits are typically more eccentric than those of the planets. The largest asteroid, Ceres, is 940 kilometers in diameter and has about 1/10000 the mass of the Earth. With over 7000 asteroids catalogued, the total number may exceed 100,000. However, their combined mass is less than 1/10 that of the Earth's Moon. All solid bodies in our Solar Systen show craters where they have collided with asteroids and comets. A few asteroids cross the Earth's orbit. The most notable of these are Apollo, Icarus, Adonis, and Eros. Hector has an orbit similar to that of Jupiter, and Hidalgo has a large elliptical orbit which extends from about the orbit of Mars out well beyond the orbit of Jupiter. Asteroid Gaspra was used in slingshot maneuver with Galileo in 1991 on the way toward ultimate rendevouz with Jupiter. Galileo also provided a close view of asteroid Ida The vast majority of the meteorites that hit the Earth are thought to come from the asteroid belt. Asteroids are classified from their observed reflectivity, with C-type asteroids making up about 75% of them. C-type or carbonaceous asteroids are dark from the high content of carbon in them. S-type asteroids contain silicate and are more reflective - they make up about 15% of the asteroids. Most of the remaining asteroids are called M-type and contain large fractions of iron and nickel. The C-type asteroids are supposed to be very primitive material that has not been significantly heated or changed chemically since they were

70. When Did The Asteroids Become Minor Planets? A brief history of the move of the asteroids from being considered planets to becoming minor planets. http://aa.usno.navy.mil/faq/docs/minorplanets.php

When did the asteroids become minor planets? by James L. Hilton Skip navigation Astronomical Applications Department ... Sitemap Search AA Discovery of the Asteroids The recent controversy over whether Pluto should be given a minor planet number and possibly be demoted from the ranks of the major planets has made me wonder about the similar controversy that occurred 150 years ago. this involved whether or not the bodies discovered between Mars and Jupiter should be considered equal to the seven other planets known at that time. Titius von Wittenburg (1766) discovered that the relative distances of the six known planets from the Sun almost fit a simple relation. The relation's problem was that it predicted there should be a planet between the orbits of Mars and Jupiter. In 1772 he published a tract proposing that a planet should exist in the gap. According to Cunningham (1988) Johann Bode, director of the Berlin Observatory so popularized this tract that the relation is now known as Bode's law. Uranus was discovered in 1781 at just the distance where Bode's Law predicted a seventh planet (including the gap between Mars and Jupiter) should be. This touched off a search for a new planet in the gap between Mars and Jupiter. The search ended on January 1, 1801 when Guiseppe Piazzi at the Palermo Observatory discovered a 'star' that had moved from its position the previous night in the constellation of Taurus

Though many new asteroids games claim to be 3D, they are in fact flat 2D games with 3D effects. GrassGames 3D Asteroids is the first asteroids game to enter the third dimension for real. Using a unique six-view screen and a special control system, your task is still to dodge and destroy asteroids, but this time you have to watch your back and every other direction you can think of. Faithful to the original, classic Asteroids game in all respects, but with an extra dimension, 3D Asteroids offers something original and fresh for all players. Version 1.4 has been fine-tuned. See more CNET content tagged: dimension games Editor's review of 3D Asteroids Fans of the original Asteroids will find this 3D interpretation plenty enjoyable, though the uninitiated may wonder what all the fuss is about. A gloomy ambience reigns in this game where you, lost in space, face hordes of asteroids and a smattering of interloping alien ships. Fortunately, the laws of physics are defied here, and you can hear the asteroids coming toward your ship and from which direction they're coming. The controls take a while to master, but you can assign new keys to give yourself a leg up. 3D Asteroids even allows saving profiles of control keys for several players. The gameplay becomes a bit monotonous, but whoever said war was a variety show? We especially recommend the game for folks who haven't forgotten the old good Asteroids.

This is the asteroid belt. These asteroids, also known as planetoids, range in size from several hundred miles to several hundred feet. At least 30,000 of these giant rocks are known to be floating in their own individual orbits between Mars and Jupiter. Scientists are not sure why there are asteroids here instead of a planet. Some believe that a large, rocky planet may have existed here in the past. This planet may have then been blasted to pieces by a cataclysmic impact. Others think that the asteroids are composed of the leftover material from which the Solar System was originally formed. The largest of these asteroids, Ceres, is over 630 miles in diameter. It was discovered by Giuseppe Piazzi in 1801.

Skip to content massachusetts institute of technology news office advanced search ... archives services request images subscribe submit news promote news ... media inquiries about us news office info MIT background contact MIT researchers reassess asteroid hazards September 5, 2003 MONTEREY, Calif.Of the approximately 1,000 near-Earth asteroids larger than 1 kilometer in diameter, one strikes the Earth on average once every 600,000 years, MIT Lincoln Laboratory researcher J. Scott Stuart reported today (Sept. 5) at the 35th annual meeting of the American Astronomical Society Division for Planetary Sciences. By combining discovery statistics with new observations of the surfaces of near-Earth asteroids (NEAs), Stuart also determined that impacts similar to the Tunguska eventin which an asteroid destroyed more than 2,000 square kilometers of forest in a remote part of Siberia in 1908are much less frequent than previously thought. Events of this magnitude occur, on average, once every 2,000 to 3,000 years. Near-Earth asteroids are small solar system objects whose orbits around the sun may bring them close to Earth. While all currently known NEAs are in safe orbits that will not cause them to collide with the Earth in the foreseeable future, many NEAs remain undetected and could be on a collision course with Earth, Stuart said. The Lincoln Near-Earth Asteroid Research (LINEAR) Project has been scanning the skies to discover and catalog NEAs and to provide advance warning of any that are bound for Earth. Since March 1998, LINEAR, whose principal investigator is Lincoln Lab associate division head Grant H. Stokes, has found 70 percent of all near-Earth asteroids discovered worldwide and is a major contributor to the NASA goal of cataloguing 90 percent of NEAs larger than 1 kilometer (0.6 miles) in diameter 2008.
