Earth orbits the Sun primarily due to the gravitational force exerted by the Sun. According to Newton's law of universal gravitation, every mass attracts every other mass with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
In the case of the Earth and the Sun, the Sun is an enormous mass compared to Earth, which creates a strong gravitational pull. This gravitational force pulls the Earth toward the Sun, while the Earth's inertia—its tendency to continue moving in a straight line—causes it to move forward. The combination of this gravitational pull and the Earth’s inertia results in an elliptical orbit, as described by Kepler's laws of planetary motion.
Additionally, the orbital motion is influenced by the initial conditions of the solar system's formation, the conservation of angular momentum, and factors such as the gravitational influences of other celestial bodies, but the fundamental reason is the gravitational attraction between the Earth and the Sun.
