The sun's gravity is pulling the planets toward it and the planets inertia keeps them moving forward
gravity and inertia combine to keep earth in orbit because the suns gravity keeps the earth in orbit and the inertia keeps the earth from going in a straight line.
The two forces that work together to keep the planets in orbit around the sun are gravity and inertia.
the planets do not orbit the moon but the moon orbits the planets because of gravity and inertia
Gravity and inertia
The inertia of earth combines with gravity to keep it from colliding with the sun

Isaac Newton concluded that the force of gravity and the forward motion of the planets combined to keep them in orbit around the Sun. The force of gravity pulls the planets towards the Sun, while the forward motion of the planets creates the centrifugal force that counteracts gravity, leading to stable orbits.

definetly Gravity and Inertia
Gravity and velocity (or inertia), and they aren't things. They're forces.
inertia keeps the planets moving and spinning , and gravity is a force that attracts all objects toward each other.
