Question

Explain how the distance of a planet from the sun affects the motion of the planet? Justify your response in two or more complete sentences.

Answer 1

it's by Kepler law of motion

1.st law:- the line joining the planet and the sun sweeps equal intervals of time.

2.nd law:- the planet and sun join with one of the foci.

3.rd law:- the square of its period of revolution around the sun is directly proportional to the cube of the distance between the planet and the sun.

i.e is

${t}^{2} \alpha {r}^{3}$

Answer 2

A planet's orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun's gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun's gravitational pull, and the slower it moves in its orbit.
