🌞 The Solar System
The Solar System is our “space family.” It is made up of the Sun, eight planets, their moons, and many other heavenly bodies like asteroids and comets.
- The Sun is at the center of the Solar System.
- The planets move around the Sun in fixed paths called orbits.
Anything we can see in the sky at night or in space is called a heavenly body.
Inner Planets (small and rocky):
Mercury – Closest to the Sun, very hot during the day.
Venus – Brightest planet, also called Earth’s twin.
Earth – Our home, the only planet with life, water, and air.
Mars – Called the Red Planet, has dusty land and big mountains.
Saturn – Known for its beautiful rings made of ice and rock.
Uranus – A blue-green planet that spins on its side.
Neptune – The farthest planet, very cold and windy.

Our Solar System is part of a galaxy called the Milky Way.

- There are billions of galaxies in the universe.
