Question

The planets do not emit light of their own. This statement is:
A. True
B. False

Answer 1

Hint: Our universe is made up of billions of different celestial bodies. Some of them are sources of light and hence emit light. Whereas some bodies do not emit light. Think about our planet earth, whether it emits light or not.

Complete step-by-step answer:
In our universe there are a variety of celestial bodies. The environment, the surface, the structure of the different celestial bodies vary a lot.
On some of the celestial bodies a lot of chemical reactions take place. Fusion and fission of atoms are one of the reactions. Due to these chemical reactions, a massive amount of heat is produced. Along with the heat, these bodies also emit electromagnetic waves which we call as light. Hence, these bodies are sources of heat and light.
The bodies that are sources of light and heat are called stars. One example is our sun.
However, not all the bodies emit heat and light. A typical example of these are planets. Planets are hard rocky or gaseous bodies. They are made up of different kinds of minerals like our planet earth.
Hence, the given statement that planets do not emit their own light is true.
Therefore, the correct option is A.

Note:Although planets do not emit their own light, they reflect light when the light from distant stars is all on them. As they appear to be shiny.
At night, the sky is full of white points. Do not misunderstand that all the shiny points are stars. Some of them may be planets as planets shine.
The points that twinkle are stars and the points that do not twinkle are planets or some other bodies that do emit light.
