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.

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.
