Text, MYTH versus REALITY
Text, Planets do not give off any light of their own.
Text, It is true that planets emit very little visible light. Most of the visible light from planets is reflected starlight. But planets also emit a significant amount of their own infrared light. In fact, the infrared light of a planet is actually easier to detect than the reflected visible light.
