Earth Revolution around the Sun
Earth Revolution around the Sun

❖ The movement of Earth currently in the Solar System is not currently orbiting the Sun.

❖ In the Solar System, the Sun is the largest object and has 1,048 times the mass of Jupiter.

❖ However, the gravitational pull which Earth exerts on the celestial body is exerted in the same or smaller amount on the planet.

❖ Kepler's third law describes the relationship between the masses of two objects mutually revolving around each other and the determination of orbital parameters.

❖ Earth orbits a barycentre and not exactly the Sun.

❖ Generally, the barycentre of the bodies in the Solar System is near the Sun.

❖ However, because of the mass, and influence of gas giants Jupiter and Saturn and orbits, it is rarely inside the Sun.

❖ Currently, the barycentre is outside the Sun and not inside it and hence, Earth is not currently orbiting it.

❖ So, the planet is revolving around a point in space and not the Sun

❖ The Earth and Moon orbit a point which is 5,000 kilometres (3,100 miles) from the Earth's centre.

❖ However, this keeps changing as the Moon slowly moves away from the Earth.
