1. The Kepler’s laws are:
- Kepler’s first law: The orbit of a planet is an ellipse with the Sun at one of the foci.
- Kepler’s second law: The line joining the planet and the Sun sweeps equal areas in equal intervals of time.
- Kepler’s third law: The square of orbital period of revolution of a planet around the Sun is directly proportional to the cube of the mean distance of the planet from the Sun.
2. The orbits of the planet are elliptical in shape.
