Comets :: Essays Papers

CometsWhat is Cometography? Cometography is a four-volume project I perplex been working on since the mid-1970s. Jump-started by comet Kohoutek of 1973-1974, I began researching comets and immediately form myself becoming more(prenominal) and more intrigued by them. It was charming to read just about comets that unexpectedly split, brightened, or faded. there were also elicit stories concerning the disc overy circumstances of some comets, as swell as tales about how comets affected cultures. As I continued practice session I found that, back in 1967, the International Astronomical inwardness suggested that an up-to-date descriptive catalog of comets or cometography was needed. A committee was formed, unless in 1970 it reported, check to the words of Brian Marsden, that it would be very nice to be possessed of a cometography, entirely that the effort required to produce such a catalog was greater than the members of the committee could devote to it. Thus be gan my inspiration to research and write Cometography, a set of books devoted to adequately presenting the details of every(prenominal) comet seen in record history. The last complete work of this type was compose by b deficiency lovage Guy Pingre. His devil volumes, called Cometographie, were published in 1783 and 1784, scarce are instantaneously greatly out of date. Not only do they obviously lack the comets seen between 1784 and the present, but untold of the original witnesser material has been retranslated over the years, so that Pingres work is now inaccurate in places. Since the time of Pingre, two other books have been published Physical Characteristics of Comets, by S. K. Vsekhsvyatskii in 1958, and Comets A Descriptive Catalog, by myself in 1984. Both of these books brought the nineteenth and 20th degree Celsius comets to readers, but in a manner much more exceedingly condensed than that of Pingre. They also only include those comets for which orbits had bee n computed. The vast tidy sum of Pingres work included comets for which orbits could not be determined, some of which have since been identify as previous, though poorly observed, appearances of Halleys comet, periodic comet Swift-Tuttle, and periodic comet dArrest. Cometography brings back the lesser observed comets, with the end of providing all necessary details that might sustain future astronomers urinate new comet identity links. To aid in the trueness of Cometography I have tried to avoid Pingres books and the book of Vsekhsvyatskii.Comets Essays PapersCometsWhat is Cometography?

The last complete work of this type was written by Alexander Guy Pingre. His two volumes, called Cometographie, were published in 1783 and 1784, but are now greatly out of date. Not only do they obviously lack the comets seen between 1784 and the present, but much of the original source material has been retransla ted over the years, so that Pingres work is now inaccurate in places. Since the time of Pingre, two other books have been published Physical Characteristics of Comets, by S. K. Vsekhsvyatskii in 1958, and Comets A Descriptive Catalog, by myself in 1984. Both of these books brought the 19th and 20th century comets to readers, but in a manner much more highly condensed than that of Pingre. They also only included those comets for which orbits had been computed. The vast portion of Pingres work included comets for which orbits could not be determined, some of which have since been identified as previous, though poorly observed, appearances of Halleys comet, periodic comet Swift-Tuttle, and periodic comet dArrest. Cometography brings back the lesser observed comets, with the intention of providing all necessary details that might help future astronomers establish new comet identity links. To aid in the accuracy of Cometography I have tried to avoid Pingres books and the book of Vsek hsvyatskii.
