Kepler devised three laws to explain: B) the motion of the planets.

According to the first law, a planet revolves around the Sun in a path similar to 1) an ellipse with the Sun fixed at one of its focus points.

Johannes Kepler(1571-1630) was an astronomer who discover the three laws of planetary movement.

These are the complete set of laws that describe the motion of planets.

1.- The Law of Ellipses. The path of the planets about the sun is elliptical in shape, with the center of the sun being located at one focus.  

2.- The Law of Equal Areas. An imaginary line drawn from the center of the sun to the center of the planet will sweep out equal areas in equal intervals of time.

3.- The Law of Harmonies. The ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their average distances from the sun.

Johannes Kepler developed three Laws that explain the motion of planets. Thus, Option B is the correct choice.

What are the three laws devised by Johannes Kepler?

There are actually three, Kepler's laws, namely, that of planetary motion:

  • Every planet’s orbit is an ellipse with the Sun at a focus.
  • A line joining the Sun and a planet sweeps out equal areas in equal times.
  • The square of a planet’s orbital period is proportional to the cube of the semi-major axis of its orbit.

This is the complete set of laws that define the planetary movement:

The Law of Ellipses: The planets in relation to the sun are elliptical, and the center of the sun is centered.

The Equality Areas: The symbolic line drawn from the center of the sun to the center of the planet will sweep the same areas at intervals of time.

The Law of Harmonies: The average square footage of any two planets is equal to the number of cubes in the distance from the sun.

Hence, Option B is the correct answer.
