A satellite is revolving around the Earth in an eccentric orbit. Choose the correct statement from the following. Correct Answer The plane of the orbit passes through the centre of the Earth always

The correct answer is option 1) i.e. The plane of the orbit passes through the centre of the Earth always

CONCEPT:

  • Kepler's first law of planetary motion:
    • It states that all the planets revolve around the sun in elliptical orbits having the sun at one of the foci.
    • This law is also known as the Law of Orbits.


​EXPLANATION:

  • Eccentric orbit is an elliptical orbit.
  • According to Kepler's first law, a satellite revolving around the Earth in an elliptical orbit will have Earth situated at one of its foci.
  • So, the centre of Earth coincides with the focus of the ellipse.
  • It is known that the focus of an ellipse lies on the plane of the ellipse i.e. plane of the orbit.
  • Thus, the plane of the orbit passes through the centre of the Earth always.
