Question
Can a satellite be in an orbit in a plane not passing through the earth's centre? Explain your answer.
✓
Answer
The centripetal force required for the orbital motion of the satellite is provided by the gravitational force of attraction. Gravitational force is a central force, i.e., it passes through the centre of mass of the earth and the satellite. Hence, the plane of orbit of the satellite has to pass through the earth’s centre.
