WHAT MAKES THE EARTH TRAVEL AROUND THE SUN?

The Earth travels around the Sun due to the combination of its orbital motion and the gravitational force exerted by the Sun.

Here’s how it works:

1. **Inertia**: Like all objects in motion, the Earth tends to continue moving in a straight line at a constant speed unless acted upon by an external force. This principle, known as inertia, describes the tendency of objects to resist changes in their motion.

2. **Gravitational Force**: The Sun exerts a gravitational force on the Earth, pulling it toward the center of the Sun. This gravitational force is what keeps the Earth in orbit around the Sun.

3. **Orbital Motion**: The Earth’s orbit around the Sun is a result of the balance between its forward motion (inertia) and the gravitational pull of the Sun. As the Earth moves forward in its orbit, the gravitational force of the Sun continually pulls it toward the center of its orbit, causing the Earth to follow a curved path.

4. **Elliptical Orbit**: The Earth’s orbit around the Sun is an ellipse, with the Sun located at one of the two foci of the ellipse. This means that the Earth’s distance from the Sun varies slightly throughout its orbit, with its closest approach (perihelion) occurring in early January and its farthest distance (aphelion) occurring in early July.

5. **Kepler’s Laws**: The Earth’s motion around the Sun follows Kepler’s laws of planetary motion, formulated by the German astronomer Johannes Kepler in the 17th century. Kepler’s laws describe the mathematical relationship between the orbital motion of planets and the gravitational force exerted by the Sun.

Overall, the Earth travels around the Sun because of its orbital motion and the gravitational force of the Sun, following a curved path due to the balance between inertia and gravitational attraction. This orbital motion determines the Earth’s position relative to the Sun, seasons, and the length of the year.
