Book excerpt: Excerpt from A Comparison of the Features of the Earth and the Moon The story of the physical conditions of the moon had best be begun by noting that the relation of our satellite to a larger sphere is not exceptional, but' the most characteristic of all the relations of one stellar body to another. Of the planets in the solar system, all save the two nearest to the sun, Mercury and Venus, have one or more smaller spheres circling about them. The relation of the sun to the several planets in a larger way repeats this plan of grouping lesser about greater orbs. It is generally believed by astronomers that the celestial spheres have been formed by a process of condensation, due to gravitation, of matter which was originally widely diffused; that our solar system, before it was organized into the sun and lesser bodies, was in the form of a diffused nebulous mass of spheroidal form which extended beyond the orbit of the outermost planet. As this matter gathered towards the center, the material now in each of the planets and its satel lites parted from the parent body, probably at first in the form of a nebulous ring, or spiral, which in time broke and gathered into a spheroidal mass. In that detached portion of the parent nebula the process of concentration was repeated, with the result that satellites, or, as we may term them, secondary planets, were formed substantially as the greater Spheres were set off from the sun. There are many questions and doubts concerning the details of this nebular theory, but that the evolution of our solar system and probably of all stellar sys tems took place in substantially the manner indicated appears to be eminently probable; it is, indeed, fairly well established by what we know of the distant nebular: and by the rings of Saturn, which apparently contain the material which normally Should have formed one or more of its satellites, but which for some unknown reason have remained unbroken. It is not certain at just what stage in the concentration of a nebula a planet or a satellite may be set off from the parent body; nor can the present distance of the satellite from the main sphere be assumed as that at which the parting took place. It is possible that the concentration of the parent body had gone so far that the diffused or nebulous stage of its materials had been passed by and the more advanced stage of igneous fluidity entered on. It is, however, more likely that in all cases the separation occurred while the particles of matter were di vided as they are in a gas or vapor. As soon as the two spheres are separated from one another, and so long as they remain in any measure fluid, the difference in their gravitative attraction on the nearer and more remote part of their masses induces tides, and the effect of these tidal movements, as has been shown by Professor George Darwin, is necessarily to impel the two bodies farther apart. It seems certain that before the earth and the moon became essentially rigid, as they now are, the effect of these tides in driving them apart must have been great enough to account for a considerable part of the interval which now separates them.

This book was released on 2016-09-13 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Lunar and Hawaiian Physical Features Compared The force of gravitation at the surface of the Moon is but one-sixth as great as it is upon the Earth, and this difference is usually given as the cause of the great compara tive size of the lunar formations. On the old theory that the lunar craters were due to explosions of steam, like our explosive volcanoes, it was evident that matter expelled from a crater vent could be thrown six times as far as upon the Earth. Although this theory is now practically abandoned, gravitation would still have an in uence on the relative size, since a cliff or pinnacle upon the Moon could be six times the height of one upon the Earth, and yet exert no greater crushing force on the material beneath it. Still it is very evident that this explanation alone is inads quate to account for the great difference in size actually observed.

Download or read book What If the Earth Had Two Moons written by Neil F. Comins and published by Macmillan. This book was released on 2010-03-30 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: "What if?" questions stimulate people to think in new ways, to refresh old ideas, and to make new discoveries. In What If the Earth Had Two Moons, Neil Comins leads us on a fascinating ten-world journey as we explore what our planet would be like under alternative astronomical conditions. In each case, the Earth would be different, often in surprising ways. The title chapter, for example, gives us a second moon orbiting closer to Earth than the one we have now. The night sky is a lot brighter, but that won't last forever. Eventually the moons collide, with one extra-massive moon emerging after a period during which Earth sports a Saturn-like ring. This and nine and other speculative essays provide us with insights into the Earth as it exists today, while shedding new light on the burgeoning search for life on planets orbiting other stars. Appealing to adult and young adult alike, this book is a fascinating journey through physics and astronomy, and follows on the author's previous bestseller, What if the Moon Didn't Exist?, with completely new scenarios backed by the latest astronomical research.

Book excerpt: The BBC’s “face of space” explores all things lunar in this comprehensive guide to the folklore, facts, and possible futures of our only natural satellite. Have you ever wondered if there are seasons on the moon or if space tourism will ever become widely accessible? So has Dr. Maggie Aderin-Pocock, astronomer and host of the BBC’s docuseries, The Sky at Night. In this lucidly written guide, Aderin-Pocock takes readers on a fascinating lunar journey. Aderin-Pocock begins with a basic overview—unpacking everything from the moon’s topography and composition to its formation and orbit around the Earth. She examines beliefs held by ancient civilizations, the technology that allowed for the first moon landing, a brief history of moongazing, and how the moon has influenced culture throughout the years. Looking to the future, she delves into the pros and cons of continued space travel and exploration. Throughout the book are sidebars, graphs, and charts to enhance the facts as well as black-and-white illustrations of the moon and stars.
