They are separated from the outer planets by the Asteroid belt. The outer planets are far away from sun and huge in size. They are Jupiter, Saturn, Uranus and Neptune. The smallest planet in our solar system Is Mercury and the largest one is Jupiter. Our solar system comes in Milky Way galaxy.

2. Venus: It is the second closest planet to the sun. Its distance from the sun is about 108 million km away.

(d) Earth is called a unique planet because of following reasons:
1. It is the only planet where life exists. The air contains some life supporting gases like O 2 .
2. The temperature of the earth is neither too hot nor too cold. Conditions favorable to support life are probably found only on earth.
3. There is water present in the earth which is very essential for the survival. There are so many geographical features on Earth like volcanoes, islands, mountains, oceans, deserts, grasslands, forests etc.

(f) The vast expanse of space or the largest unit in which life exists is called Universe. It is infinite in volume. The three most common elements in universe are Hydrogen (H 2 ), Helium (He) and Oxygen (O 2 ). The universe is so dark that it is invisible and is also called as ‘dark matter’.
