Comets, Meteors and Asteroids Comets Currently Visible C/2001A2 - Discovered on images obtained on 2001 January 15.32 from the LINEAR project. It was initially mag 15.8 at the time of discovery. In June 2001 the comet reached a mag of ~3.5 but was not visible in norther latitudes until late June. On July 1 one of our own club members, Kevin Black, reported "...4th magnitude it is bright and BIG!" Cometography.com has a good write-up on comet 2001 A2. Orbital Elements 41P/Tuttle-Giacobini-Kresak - First discovered in 1858 by Horace Parnell Tuttle. Period 5.8 to 7.5 years. This comet had a series of brightness outbursts of about 10 magnitudes in 1973 with a maximum brightness of magnitude 4.5. This comet is not an easy target in January 2001 because of an elongation of 42 degrees, a declination of about -15 degrees and a maximum magnitude of 10 to 15. This is not an easy target for northern observers. Orbital Elements C/1999 T1 (McNaught-Hartley) - First discovered by Robert H. McNaught on a plate exposed by Malcolm Hartley on October 7. Period 344.7 days. Perihelion occured on 2000 December 9.6 at a distance of 1.15 AU. September 2000 magnitude estimates by Australian observers were between 10 and 10.5. At the end of November the comet became observable by northern hemisphere observers at magnitude 8.5.

Comets are insubstantial bodies, loosely knit assemblages of frozen gas and dust that loop around the Sun on highly elongated orbits. They return to the inner Solar System at intervals ranging from a few years to many thousands of years, becoming visible to us on Earth as ghostly, glowing apparitions for a few weeks or months before receding back into obscurity. Our Galaxy has two small companion galaxies called the Magellanic Clouds. To the naked eye they appear like detached portions of the When far from the Sun, a comet shines only by reflecting sunlight. At that stage it is small usually no more than a few kilometres across and faint. Approaching the Sun, the comet warms up, turning its icy surface into gas. Under the influence of the Sun's radiance the gases of the comet begin to fluorescence, in similar fashion to the gas in a neon tube, thereby considerably increasing the comet's brightness. Gas and dust released from the warming comet produce a halo or coma 100,000 km or so in diameter. At the centre of the coma is the nucleus, the only solid part of the comet, consisting of a "dirty snowball" of ice, dust and perhaps some rock. In a large comet the nucleus may be a few tens of kilometres across, but most are only a kilometre or so wide. Well over a thousand million comet nuclei would be needed to equal the mass of the Earth. Not all comets develop tails, but many do. One part of the tail consists of gas blown away from th comet's head by the solar wind of atomic articles streaming from the Sun. The other part of the tail is made up of dust particles liberated from the head by the evaporating gases. Comet tails always point away from the Sun. A comet's tail can extend for 100 million km or so, further than the distance from the Earth to the Sun, as did the gas and dust tails of Comet Hale-Bopp in 1997. Yet, for all its glorious appearance, the tail is less dense than a laboratory vacuum stars shine through it undimmed. The tail of a comet gives it the appearance of speeding across the sky, but actually its movement against the stars is barely noticeable during the course of a night.

Home Catalogue Related Areas: New titles Email For updates on new titles in: Fire in the Sky Comets and Meteors, the Decisive Centuries, in British Art and Science Roberta J. M. Olson, Jay M. Pasachoff Paperback In stock Comets and meteors are spectacular and awe-inspiring natural phenomena, which are among nature’s most compelling icons. Since the beginning of recorded time, they have mesmerized people, not least among them artists and astronomers. Britain during the eighteenth and nineteenth centuries produced a larger number and greater variety of representations of comets and meteors than any other country. The development of new technologies, and the burgeoning interest of the general public in science and art, dovetailed with the inherent British interest in nature and a strong literary tradition of comet and meteor symbolism. This beautifully illustrated book examines the link between these works and the achievements of British science in the wake of Newton and Halley. This book will be stimulating to anyone interested in the art or astronomy of comets. Reviews ‘ an intriguing book it is beautifully and profusely illustrated As a text, this book is not only eminently readable, erudite and full of insight, but also skilfully weaves together the conversion of comets from mere celestial wanderers to objects of considerable astrophysical interest, the development of the public’s interest in comets, and the advances in art as paintings and prints eventually competed with chromolithographs and photographs. The authors and publishers must be congratulated on bringing this fascinating symbiosis between science, politics and art to the attention of a wider public.’David Hughes, New Scientist

Comets, Quasars, Meteors The following questions were answered by astronomer Dr. Cathy Imhoff of the Space Telescope Science Institute. Where do comets come from? We think that comets are sort of "cosmic leftovers" from the formation of our solar system. There seems to be millions of them far, far out in our solar system, far beyond the orbit of Pluto. They are made up of ice, rock, and dust. They are much smaller than they look. The comet itself may only be a mile across but the tail can be millions of miles long (but it's just thin gas and dust). Why does a comet have a tail behind it? Can meteors hit the earth? You may be surprised that meteors hit the earth all the time! The vast majority are very small and burn up when they hit the earth's atmosphere. A few make it through and hit the ground or fall into the ocean. I have one, about the size of a pebble, in my rock collection. It is very rare for a meteor big enough to do any damage to hit the earth. Have you ever heard of the Meteor Crater in Arizona? I have visited it. It's about a mile across and occurred about 25,000 years ago. Fortunately these days, astronomers are tracking all the larger objects and keeping track of them in orbit. Hopefully if one if them looks like it might hit the earth, we can do something about it. What is the difference between a meteor shower and a meteor storm?

Most are pitted with impact craters and dust left from collisions with other objects in the solar system. Some asteroids have other asteroids orbiting them as in the picture at right, the Asteroid Ida and its moon Dactyl. A group of asteroids orbit the sun called Near-Earth Asteroids because they are somewhat close to the Earth and occasionally may cross Earth's orbit. Could any hit the Earth?

Page 83: "A small comet of water-snow impregnated with minor amounts of cosmic dust should emulate the visual signature of these dustballs."...."Dustballs start out like a very big bright rock, but travel only a short distance, then snuff out." page 82 He gets slightly into "nebulous meteors" on page 85. "Nebulous meteors are generally thought to be loose clumps of fine debris of cometary origin. But unfortunately there is no organized information on these observations. There is nothing that allows us to document what is happening here. So I cannot say with any certainty that nebulous meteors have any bearing on the topic of small comets."
