Space and planets are topics of endless fascination to kids and part of every grade-school curriculum. Yet because of the history-making reassignment of Pluto from "planet” to "dwarf planet” on August 24, 2006, all books on the solar system are now out of date. Enter When is a Planet Not a Planet? The Story of Pluto by Elaine Scott, an esteemed writer of non-fiction for children. Scott is the first to put the answer to the title question into terms simple enough for a very young audience to understand, based upon the new definitions determined by the International Astronomical Union. Well-researched and accompanied by large, awe-inspiring photographs and paintings, this exciting new book makes clear what astronomers have argued about for decades.

Nasmyth's wonderfully evocative representations of the lunar surface are the most realistic ever produced by earthbound observers. James Nasmyth was not only the inventor of the steam hammer, that great symbol of victorian engineering, but was also an enthusiastic astronomer. He built a series of increasingly powerful telescopes and won a prize medal at the Great Exhibition for his drawings of the lunar surface (he had inherited a talent for drawing from his father, the painter Alexander Nasmyth.) He then made models of the lunar surface, based on his observations and drawings and the prints in this book are from photographs of these models taken in bright sunlight. Besides the plates the book is important for the discussion of the origins of the moon's physical geography.

THIS Essay aims at a complete calculation of the effects produced by the action of a planet on the motion of the moon under the following limitations and conditions: (1) The problem of the motion of the moon under the action of the sun (supposed to move round the centre of mass of the earth and moon in a fixed elliptic orbit) and the earth, is considered to have been completely solved.(2) All the bodies are supposed to attract in the same manner as particles of masses equal to their actual masses and situated at the centres of mass.(3) All the planets are supposed to move in fixed elliptic orbits, i.e., the effect of the action of a planet transmitted either through the earth or through another planet is neglected.(4) Perturbations of the first order with respect to the ratio of the mass of a planet to that of the sun are alone calculated.(5) The exception to the above limitations occurs in the periods of revolution of the apse and node of the moon's orbit. These periods are not exactly those arising from (1) but they are the observed periods or, what amounts to the same thing owing to the close agreement between the observed and calculated periods, the periods after all known causes have been included. The point is only of importance in terms of very long period.(6) All coefficients greater than 0"·01 in longitude, latitude and parallax have been obtained. Many are also given which are less than 0"·01 whenever they have been accurately calculated. There are, in addition, classes of terms of short period which run in series and which in the aggregate will add up at certain times to much more than 0"·01: these have been found to be 0"·002.(7) The maximum period considered is 3500 years, but as the sieve in Section iv. retained a few terms of longer period, these were also included in the general scheme

The solar system most of us grew up with included nine planets, with Mercury closest to the sun and Pluto at the outer edge. Then, in 2005, astronomer Mike Brown made the discovery of a lifetime: a tenth planet, Eris, slightly bigger than Pluto. But instead of adding one more planet to our solar system, Brown’s find ignited a firestorm of controversy that culminated in the demotion of Pluto from real planet to the newly coined category of “dwarf” planet. Suddenly Brown was receiving hate mail from schoolchildren and being bombarded by TV reporters—all because of the discovery he had spent years searching for and a lifetime dreaming about. A heartfelt and personal journey filled with both humor and drama, How I Killed Pluto and Why It Had It Coming is the book for anyone, young or old, who has ever imagined exploring the universe—and who among us hasn’t?

"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.

For many years, it was accepted as fact that our solar system had nine planets. However, one important meeting of astronomers in 2006 reduced that number to eight. They decided that Pluto was not a planet, a declaration that outraged some people. Readers will learn more about distant Pluto, such as how it was accidentally discovered. Brilliant photographs accompany the fascinating facts.
