Answer The motion of a planet is balanced between falling toward the sun and moving in a straight line past the sun. The resultant path is a curved orbit around the sun.

Did you know…? When you consider the motion of the Earth’s rotation, the Earth’s revolution around the sun and the sun’s movement around the Milky Way galaxy, you are actually travelling more than 900,000 km/h just standing still.

Closure Question Suppose a certain planet had two moons, one of which was twice as far from the planet as the other. Which moon would complete one revolution of the planet first? Explain.
