Text, MYTH versus REALITY

 

Myth side

 

Text, Planets do not give off any light of their own.

 

Reality side

 

Text, It is true that planets emit very little visible light. Most of the visible light from planets is reflected starlight. But planets do emit a significant amount of their own infrared light. In fact, the infrared light of a planet is often easier to detect than the reflected visible light.
