From the reviews: "David Seargent has the enviable ability to pick his way through an enormous amount of detail and to spice up our understanding of planets, moons, asteroids, and comets with the odd and interesting aspects of their physics and chemistry. He expertly balances the depth of our knowledge against the huge number of unknowns. ... this engagingly written, introductory-level, and extremely accessible book will do much to encourage more people to investigate planets." (David W. Hughes, The Observatory, Vol. 134 (1239), April, 2014) "Seargent (Australian Sky and Telescope) begins with the most curious features of the major planets, and then leads readers to some of the innumerable minor bodies in the solar system, such as asteroids, comets, moons, Kuiper Belt objects, and dwarf planets like Pluto and Ceres. ... While Weird Worlds is certainly an excellent introduction to planetary science, it is really a tour guide of the solar system--and beyond. Summing Up: Recommended. All levels/libraries." (T. D. Oswalt, Choice, Vol. 51 (4), December, 2013)
