Our World – Notes

The Solar System

The solar system is made up of the sun, the eight planets and the other bodies like satellites, asteroids, meteoroids and comets.

Earth is a part of the solar system, which is a part of the Milky Wave galaxy

(Akash Ganga).

The sun exerts a force on all the other bodies that holds the solar system together.

We do not feel its tremendous heat as it is 150 million kilometres away.

All the eight planets move around the sun along fixed paths called their orbits.

The paths along which the planets move around the sun are elliptical orbits.
