For example, they are often irregular in shape. Several hundred such asteroids are now known; it is estimated that there may be a thousand or more altogether. Forces exerted on the coma by the Sun’s radiation pressure and solar wind cause an enormous, elongated tail to form. (more…)...

The Planet Observer's Handbook

Format: Paperback Language: English Format: PDF / Kindle / ePub Size: 5.49 MB Downloadable formats: PDF Christopher Chyba, Paul Thomas, Leigh Brookshaw and Carl Sagan wrote a study of this problem, published in Science in 1990, entitled "Cometary Delivery of Organic Molecules to the Early Earth" (12). Could this be the meaning behind theLaguna Canyon formation? The Younger-Dryas Event suggests that a large comet exploded above Canada, creating a storm of fiery fragments that rained over North America. Thus, astronomers think that their composition tells us about the conditions in the early Solar System when the planets were forming. (more…)...
