Question

planets in the solar system are in constant motion. what factor has the greatest effect on the orbits of the planets?
o the size of the planets
o gravitational pull of the sun
o the composition of the planets
o distance of the planets from the sun

Explanation:

According to Newton's law of universal gravitation, the gravitational pull between two objects affects the motion of the objects. The Sun's gravitational pull is the dominant force that keeps the planets in their orbits. The distance from the Sun, composition of planets and size of planets also play roles but the gravitational pull of the Sun has the greatest impact on the orbits of the planets.

Answer:

gravitational pull of the Sun
