Samenvatting:

Thomas Wm. Hamilton’s latest book, Astronomical Numbers, provides most of the commonly referenced and used numbers in astronomy.This includes the diameters of the sun, all the planets, and major moons, distances of orbits, magnitude scales, frequency of eclipses, the five different kinds of lunar month, and more.To maximize usefulness, all values are in both English units (e.g. miles) and metric (e.g. kilometers), and provide conversions for units commonly used in astronomy, such as the astronomical unit, lightyear, and parsec.Says the author, “There is a real need for a convenient and quick reference for all this astronomical data, which is scattered and time-consuming to find.”
