In addition to discovering the shapes of planetary orbits, __ showed that planets move faster when the are closer to the Sun. Type your answer...

## Step 1<br />The problem is asking for the name of the person who discovered that planets move faster when they are closer to the Sun. This is a historical fact in the field of astronomy.<br />## Step 2<br />The person who made this discovery is Johannes Kepler. Kepler was a German astronomer who is best known for his laws of planetary motion.<br />## Step 3<br />Kepler's second law, also known as the Law of Equal Areas, states that a planet's speed varies so that the line between the planet and the Sun sweeps out equal areas during equal intervals of time. This means that planets move faster when they are closer to the Sun and slower when they are farther away.
