Habitable Planets for Man
Stephen H. Dole
Habitable Planets for Man examines and estimates the probabilities of finding planets habitable to man, where they might be found, and the number there may be in our own galaxy. The author presents in detail the characteristics of a planet that can provide an acceptable environment for humankind, itemizes the stars nearest the earth most likely to possess habitable planets, and discusses how to search for habitable planets. Interestingly for our time, he also gives an appraisal of the earth as a planet and describes how its habitability would be changed if some of its basic properties were altered. This is a reprint of an edition originally published in 1964.
