Mercury,Venus, Earth, and Mars Orbiting the Sun

The closer the planet is to the Sun, the faster it's orbital speed. So the nearest planet to the Sun (Mercury) goes around the Sun many times (approximately 8) for every one time that the farthest planet (Mars) goes around. Mercury goes around the Sun approximately 1100 times for every time that the most distant planet, Pluto (not shown) goes around once.
