24.0 Earth, Moon, and Sun

From out in the solar system, Earth and Moon appear as one dot of light. The two bodies are linked tightly together by their mutual gravitational attraction. Yet they could hardly look more different. One reveals nothing but craters, geologically dead. The other is covered with blue oceans, swirling clouds, and lands that vary from brown to bright green. Despite their differences, the two bodies have a shared history. Moon was born from Earth’s side! Both of these bodies share the same spot in space, a spot as the 3rd object out from the Sun. The Sun may be an ordinary star, but it reveals all sorts of wonders for the interested observer.
