Which force is responsible for keeping Earth in orbit around the Sun?
Quick Answer
Gravity keeps Earth in orbit around the Sun. The Sun’s mass curves spacetime and pulls Earth into a stable path.
The Full Story
Earth orbits the Sun because gravity provides the centripetal acceleration needed to keep the planet moving along a curved path instead of flying off in a straight line. In Newtonian terms, the Sun’s gravitational pull keeps Earth bound; in Einstein’s description, Earth follows a geodesic in curved spacetime. The average Earth-Sun distance is about 1 astronomical unit, or 149.6 million kilometres. Without gravity, there would be no planetary orbits and no Solar System as we know it.

1.1 astronomical unit is about 149.6 million km
2.Earth completes one orbit in about 365.25 days
3.The Sun contains about 99.86% of the Solar System’s mass
