Read the passage below and answer the questions that follow:
When we look up at the night sky, we can see both stars and planets in a single gaze. But do we know that though they look similar, they differ from one another in many ways? In fact, most of the glittering dots in the sky are huge balls of fire like our sun. But we do not feel their heat because they are trillions of miles away from us. Unlike the stars, planets are balls of cold gas or solid rocks and they revolve around their respective stars. Earth and its neighbouring Mars are planets that move around the sun. Stars are of different sizes and colours. The newly born stars are bluish white. When stars come near the end of their life, they become white, small and dense. These stars are called "White Dwarfs". Huge stars that have burned most of their fuel turn red and are called "Red Giants". Like stars, planets also vary in colour and size. Our planet is like a small ball compared to Jupiter, which is a huge ball of gas and is called a "Gas Giant". Saturn is another Gas Giant in our solar system which has a beautiful set of rings. The earth looks blue, the Mars is red, while the Jupiter is Orange.
