(a) How does a planet differ from a star? (b) What is meant by the ‘Solar System’? (c) Name all the planets according to their distance from the sun. (d) Why is the Earth called a unique planet? (e) Why do we see only one side of the moon always? (f) What is the Universe?


(a) Differences between a planet and a star:

(b) The term Solar System refers to the “family” of the Sun. The Sun is a star around which eight planets, among other celestial objects, revolve in orbits. This whole system of bodies is called the Solar System. The Sun is the “head” of this system.

(c) The list of planets in the order of their distance from the Sun is as follows:

· Mercury

· Venus

· Earth

· Mars

· Jupiter

· Saturn

· Uranus

· Neptune

(d) The Earth is regarded as a unique planet because of the following reasons:

· It is the only planet known to support life. It has oxygen and water present in proportions that allow life to thrive.

· It also has a temperature range that supports life.

· The proportion of water present is about two-thirds of the surface of the earth when compared to land.

(e) One revolution of the moon around the earth takes about 27 days. Incidentally, the moon’s rotation about its own axis also takes nearly the same time. One day of the moon is equal to 27 Earth days. So only one side of the moon can be seen from the earth.

(a) The sun is considered the “head” of the solar system. It is a star, although it is smaller and less bright than most other stars. It is a huge celestial body made up of extremely hot gases. It provides heat and light for the whole of the solar system. Life on earth depends on many factors, and the sunlight is one of them. The sun is about 150 million kilometers away from the earth.
