Planets revolve around the Sun in elliptical orbits. One of the foci of the elliptical orbit is the Correct Answer ​location of Sun

The correct answer is option 3) i.e. ​​location of Sun

CONCEPT:

  • Kepler's laws of planetary motion
    • The first law (Law of orbits): All the planets revolve around the sun in elliptical orbits having the sun at one of the foci.
    • The second law (Law of areas): The radius vector drawn from the sun to the planet sweeps out equal areas in equal intervals of time.
    • Third law (Law of periods): The square of the time period of revolution of a planet around the sun in an elliptical orbit is directly proportional to the cube of its semi-major axis.

  • From Kepler's law of orbits, the planets have an elliptical orbit around the Sun and the Sun is situated at any one of its foci.
