What two things keeps the planets, asteroids, comets and moons in orbit?

Answers

answer:

The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun's gravitational pull, all the planets in our solar system orbit around it.

The mutual force of gravitational attraction between the sun and each object does that.

This is all it takes, which is lucky because this is all there is.
