Kepler's Law Review:

Planets orbit the Sun in a shape called a(n)

• circle
• ellipse
• focus
• perihelion

When a planet orbits the Sun, one of the foci of the elliptical orbit is

• the axis

• the perihelion

• the center

• the star

A planet moves fastest during its orbit around the Sun when...

• it is closest to the sun and gravity has a stronger pull

• it is farthest from the sun and gravity has a stronger pull

• it is closest to the sun and gravity has a weak pull

• it is farthest from the sun and gravity has a weak pull

Kepler's third law of planetary motion describes a relationship between the

• shape of orbit and location of Sun.
• orbital velocity and position in orbit
• distance from the Sun and length of year.
• path of epicycle and position.

The speeds of the planets orbiting a star depend largely on...

• their distances from the sun.

• the masses of the planets.

• their periods of rotation.

• None of the above are correct.
