GED® Science: The Solar System & Earth in Space (Deep Dive)

A deep dive into our cosmic neighborhood, expanding the single 'Solar System & Earth in Space' lesson from the GED® Earth & Space Science course into a full mini-course. You'll start with the Sun -- a star powered by nuclear fusion -- then tour the eight planets, split into the small rocky worlds and the giant gas-and-ice worlds. You'll learn why gravity keeps planets in orbit, meet the asteroids and comets, and get a feel for the staggering scale of space and how astronomers measure it. Plain language, all-new labeled diagrams, common-misconception warnings, and GED®-style practice with full explanations throughout.
