“On the Measurement of the Earth” continues the tradition, which dates back to ancient Greece and the time of Eratosthenes, of works on geodesy. The title is that of the lost work of Eratosthenes on the subject. Cherishing our planet through attention to its dimensions allows us to “know our place” and enjoy the wisdom that comes from this awareness. That the Earth has an ellipsoidal, not spherical, shape is well known. While Chimborazo’s resulting status as the point farthest from the Earth’s centre is generally understood, many other implications are unappreciated or hitherto undocumented. These include consideration of how to define the height of a mountain, calculation of the place closest to the Earth’s centre, a formula for calculating distance to the Earth’s centre for any point, a list of summits based on distance from the centre of the Earth and corrected for the geoid, calculation of the Earth’s fastest-moving points, and new “Seven Summits” lists. The new concept of terrahelion allows calculation of the land point on the Earth’s surface that comes closest to the Sun each year at perihelion. The insights that result from these new considerations of planetary shape provide new exploration opportunities
