SUMMARY
The visible light intensity on Pluto is not equivalent to that on Earth; 1 lux on Pluto does not equal 1 lux on Earth. Light intensity diminishes according to the inverse square law, meaning that as distance from the Sun increases, the intensity of light decreases. This reduction in intensity is due to the spreading of light over greater distances, not merely the time it takes for light to travel. Therefore, images of distant solar system objects often require longer exposure times to capture sufficient light.
