Front

Who did Kepler work closely with to discover the true nature of planetary orbits?

Back

Brahe

Front

What is Kepler's First Law?

Back

The orbit of a planet is an ellipse with the Sun at one of the two foci.

Front

What is Kepler's Second Law?

Back

A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time.

Front

What is the semi-major axis in an elliptical orbit?

Back

The longest radius of an ellipse, half the longest diameter.

Front

What is the relationship between a planet's distance from the Sun and its orbital period according to Kepler's Third Law?

Back

The square of the orbital period is proportional to the cube of the semi-major axis.

Front

What is aphelion?

Back

The farthest distance an orbiting object is from the Sun.
