Which of the following best describes Kepler's First Law of planetary motion?

• Planets move in circular orbits with the Sun at the center.

• Planets move in elliptical orbits with the Sun at one of the foci.

• Planets move in parabolic orbits with the Sun at the vertex.

• Planets move in hyperbolic orbits with the Sun at one of the foci.

Kepler's Second Law is also known as the law of:

• Equal areas

• Equal distances

• Equal velocities

• Equal times
