Seven Wonders of the Rocky Planets and Their Moons

By Ron Miller

The seven wonders of the rocky inner planets (Mercury, Venus, Earth, and Mars) are: the 16-mile-high mountain on Mars; a Martian canyon 3-4 miles deep; Earth's very large moon; the true facts about lovely Venus; the Mars-filled sky of its tiny moon, Phobos; Mercury, with the most erratic of all orbits in our solar system; and the wonder of life on Earth.
