Gravity Part 2

The more massive an object, the greater it's gravitational pull

The closer the distance between objects, the greater the gravitational pull

The gravitational pull between the Sun and each planet or between Earth and it's moon causes distinct motions between and among the objects

The Sun's gravitational attraction along with a planet's inertia (continued forward motion), keeps the planets moving in an elliptical orbit (slightly oval) & determines how fast they move.

Planets nearer to the Sun move/orbit faster due to the higher gravitational pull from the Sun.

Planets farther from the Sun move/orbit slower due to the gravitational pull becoming less the farther from the Sun a planet is located.
