Abstract
“How old is the Earth?” was a topic of scientific inquiry in the late nineteenth century. In the twentieth century the question became “How old are the Earth and other objects in the Solar System?” Related questions are: “How old is the Solar System?”; “How has the Earth changed over geologic time?”; and “How have the planetary bodies in the Solar System changed over time?” Also, “What has made Earth unique in our Solar System?” With the aid of spacecraft-acquired data and samples, and through the study of lunar and Martian meteorites, we are beginning to answer some of these questions as they relate to the Moon and Mars.
