Question

When the planet comes nearer the sun, it moves

• A. fast
• B. slow
• C. constant at every point
• D. none of the above

Answer 1

The correct option is A fast

Keplar's third law suggests that the square of orbital period of a planet is directly proportional to the cube of the semi-major of its orbits, thus capturing the relation between the distance of planets from the sun, and their orbital periods.Thus when the planet comes near to the sun, it moves faster.
