This book was released on 2016-12-19 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a compilation of the research presented at the International Asteroid Day workshop which was celebrated at Barcelona on June 30th, 2015. The proceedings discuss the beginning of a new era in the study and exploration of the solar system’s minor bodies. International Asteroid Day commemorates the Tunguska event of June 30th, 1908. The workshop’s goal was to promote the importance of dealing proactively with impact hazards from space. Multidisciplinary experts contributed to this discussion by describing the nature of comets and asteroids along with their offspring, meteoroids. New missions to return material samples of asteroids back to Earth such as Osiris-REx and Hayabusa 2, as well as projects like AIM and DART which will test impact deflection techniques for Potentially Hazardous Asteroids encounters were also covered. The proceedings include both an outreach level to popularize impact hazards and a scientific character which covers the latest knowledge on these topics, as well as offering proposals of promising new techniques that will help gain new insights of the properties of these challenging bodies by studying meteoroids and meteorites. Asteroids, comets, meteoroids and meteorites are introduced with descriptions of their nature, origin, and solar system pathways.
Download or read book Meteor Showers and their Parent Comets written by Peter Jenniskens and published by Cambridge University Press. This book was released on 2006-09-14 with total page 804 pages. Available in PDF, EPUB and Kindle. Book excerpt: Meteor Showers and their Parent Comets is a unique handbook for astronomers interested in observing meteor storms and outbursts. Spectacular displays of 'shooting stars' are created when the Earth's orbit crosses a meteoroid stream, as each meteoroid causes a bright light when it enters our atmosphere at high speed. Jenniskens, an active meteor storm chaser, explains how meteoroid streams originate from the decay of meteoroids, comets and asteroids, and how they cause meteor showers on Earth. He includes the findings of recent space missions to comets and asteroids, the risk of meteor impacts on Earth, and how meteor showers may have seeded the Earth with ingredients that made life possible. All known meteor showers are identified, accompanied by fascinating details on the most important showers and their parent comets. The book predicts when exceptional meteor showers will occur over the next fifty years, making it a valuable resource for both amateur and professional astronomers.

This book was released on 1968 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: In any statistical study of characteristics of meteors with data obtained from photographs, corrections must be made for two inherent biasing effects due to the brighter trails left by meteors of greater mass and/or by meteors of greater velocity relative to Earth's atmosphere. In the past, attempts have been made to correct for both biasing effects with a weighting factor inversely proportional to the square of the meteor velocity relative to atmosphere. A new analysis has been made to investigate the magnitude of the weighting factor, specifically for application to photographic meteor data published by Smithsonian Institution Astrophysical Observatory. As a result of this analysis, a revised factor was obtained to operate upon actual counts of photographic meteors within various classes of velocity to provide a correct ratio of counts for all velocities reduced to any given lower mass limit. In the analysis, an expression was derived theoretically for maximum effective exposure on the photographic plate produced by a meteor in terms of the original mass of the particle, its velocity relative to Earth's atmosphere, and the angle of its path to the zenith. The expression for maximum effective exposure was tested and revised by application to 100 test meteors that were believed to have provided approximately uniform effective exposure density. The revised expression for maximum effective exposure was combined with a widely accepted equation for the influx rate of meteors of mass greater than a stated value to obtain approximately the desired weighting factor. The manner of the combination eliminated mass of the meteor particle from the factor. The analysis indicated a large change in value of the exponent of velocity relative to Earth's atmosphere in the weighting factor, namely, from -2 downward at least to -3.85 and possibly as low as -4.22. Application of the new factor should cause a significant reduction of estimates of average meteor velocities relative to the atmosphere. Extensive changes would also be required in estimates of other parameters that might bear a systematic relation to meteor velocities.
