As the planet moves the line sweeps out an area that is ... The equation for Kepler’s Third Law is P² = a³, so the period of a planet’s orbit (P) squared is equal to the size semi-major ...

Kepler’s second law says that a line joining a planet and the Sun sweeps out equal areas during equal intervals of time. Thus, a planet moves fastest when it’s closest to the Sun (at a point ...

Kepler’s second law: Each planet revolves around the sun in such a way that the line joining the planet to the sun sweeps over equal areas in equal intervals of time. We know that a planet moves ...

Now, if you’ve studied Kepler’s laws, you might raise an objection here: "What about the equal areas in equal times?" Yes, the most common way of stating Kepler's second law is that a planet ...
