Yale-New Haven Teachers Institute Home Asteroids, Comets, and Meterorites: Their Intimate Relation with Life on Earth by Stephen P. Broker Contents of Curriculum Unit 96.06.03: I. Introduction (What Is Biogeoplanetology?) II. The Early Solar System (Why Did The Solar Nebula Not Remain Nebulous?) III. The Solar System Today (What’s The Next Surprise Going To Be?) IV. The Asteroids (Why Is There No Planet Between Mars And Jupiter?) ... To Guide Entry I. INTRODUCTION (WHAT IS BIOGEOPLANETOLOGY?) This curriculum unit presents an interdisciplinary approach to the study of science, bringing together information from astronomy, earth science and ecology. The unit, written as part of the seminar “Outstanding Problems in Contemporary Astronomy and Cosmology,” addresses the question, “how is and how has life on Earth been influenced by events occurring in our Solar System?” More specifically, I present information on the relation between asteroids, comets and meteorites and life on Earth. I review current scientific thinking about how our Solar System’s asteroids and comets interacted with a young Earth to create the necessary conditions for the origin of life, and how meteoritic impacts have altered the evolution of life through Earth history. Sample teaching strategies are presented to suggest ways of presenting the subject matter to students. In developing this topic, I have drawn on my deep interest in ecology and an interest in earth science, including the fields of paleontology and mass extinction theory. The Teachers Institute seminar has been an excellent vehicle for learning more about astronomy and cosmology, especially solar system astronomy and planetary science. It has given me an opportunity to read and talk about issues in astronomy and to combine pertinent information from the fields of astronomy, earth science, and ecology.

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 605 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.

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 won’t 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 game’s premise, which remains faithful to the original.

104. IOTA Asteroidal Predictions 2004 IOTA Asteroidal Predictions for the Western Hemisphere Notes on Events Upcoming Events (D. Dunham External Link). Listed in http://www.lunar-occultations.com/iota/asteroids/astrndx.htm

2004 IOTA Asteroidal Predictions for the Western Hemisphere Notes on Events 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 Are also known as the Minor Planets. Orbit the Sun mainly between the orbits of Mars and Jupiter. Usually range in size from 1 kilometer to 1000 kilometers across. Are difficult to observe because of their small size. Gaspra (above) and Ida (right) are two known Asteroids. Ceres, Pallas, Juno and Vesta are some other of the larger Asteroids. Sometimes have moons that orbit them. Notice the small moon that orbits Ida (right).

The ground shakes. Fire arcs across the sky and beyond the horizon. Clouds of debris race around the planet and blot the Sun out for months. At least that's what theory tells us. Since the scenario has never played out in modern times, scientists don't really know exactly what will happen when the next space rock slams into Earth. One long-supposed incendiary side-effect is enhanced volcanic activity, which can make life pretty miserable for survivors who find themselves on or near the flanks of a newborn plume of molten rock.

Scientists used various methods to estimate 100,000 asteroid's ages from 6 million to 3 billion years. Our Sun is 4.6 billion years old, and asteroids formed shortly after its birth. Many have collided since, sometimes coming together to make larger rocks and sometimes being broken into fresh, smaller pieces. The new study appears to answer an old question about why small meteorites, which are chips off asteroids, are often a different color than the typical asteroid.

Astronomy, science dealing with all the celestial bodies in the universe, including the planets and their satellites, comets and meteors, the stars and interstellar matter, the star systems known as galaxies, and clusters of galaxies. Modern astronomy is divided into several branches: astrometry, the observational study of the positions and motions of these bodies; celestial mechanics, the mathematical study of their motions as explained by the theory of gravitation; astrophysics, the study of their chemical composition and physical condition from spectrum analysis and the laws of physics; and cosmology, the study of the universe as a whole.

REASONS TO VISIT See relics of the formation of the Solar System Some asteroids have carbon-bearing compounds and may have delivered organic, life forming chemicals to the early Earth In future, mining asteroids could provide raw materials for colonising space Solar System Jigsaw Can you build the Solar System? WHAT TO SEE 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.

116. Asteroids asteroids asteroids are rocky and metallic objects too small to be considered planets. asteroids on a collision course with Earth are called meteoroids. http://csep10.phys.utk.edu/astr161/lect/asteroids/asteroids.html

Asteroids Asteroids are rocky and metallic objects too small to be considered planets. They are sometimes called minor planets . They range in size from Ceres, with a diameter of about 1000 km, down to a few centimeters or less. The ajacent image shows the asteroid Gaspra, as photographed by the Galileo space probe (Ref) . The name asteroids, meaning "star-like", derives from the fact that, compared with comets, they are star-like in appearance because since they are rocky they do not emit the gases and dust that give comets their fuzzy appearance. Asteroids on a collision course with Earth are called meteoroids . If this meteoroid burns up because of frictional heating when it strikes our atmosphere, we term it a meteor (colloquially, a "shooting star"). If the meteoroid doesn't burn up completely and strikes the Earth we call it a meteorite . We shall discuss, meteoroids, meteors, and meteorites in the next section. Next Back Top Home Help

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.
