Speed of light in all planets and Moon.

Hi prashantakerkar

The speed of light is at its maximum in a perfect vacuum. The medium dictates its speed, so depending on the planet's atmosphere, it could be different. To put it in perspective, take a look at the following illustration:

Can we compute Speed of Light on Moon?

Is there complete darkness on the Moon?

If not, Can we compute Speed of light on Moon?

Since the moon has a thin atmosphere, the speed of light on the moon is nearly the same as it would be in a perfect vacuum (space). The difference would be negligible.


There are "two sides" of the moon, namely the one we can always see and the far side. About 59 percent of the moon is visible from Earth over the course of an orbit. We never ever see 41 percent of the moon - the side that many call dark side, or far side. The reason is, the Moon takes about 29 days to orbit the Earth. It takes almost the same amount of time to make one rotation on its axis. The side of the Moon we do not see from Earth gets just as much sunlight on it as the side we do see. In truth, the only dark side of the Moon is the side that is pointed away from the Sun at any given time. That being said, both sides of the Moon experience two weeks of sunlight followed by two weeks of night. We can conclude that only when the farside is pointed away from the sun does it not get any light.


Yes. Light travels through space at just over 186,000 miles per second. The moon is just under 250,000 miles from Earth, so light from the Moon's surface has to travel more than one second (about 1.3 seconds) to reach us. So, if an explosion occurred on the moon, it'd take 1.3 seconds to reach our eyes.
