The moon is 238,855.086 miles from Earth.
The speed of light is 670,616,629 mph.
Therefore:The minimum distance from the sun to the moon is 91,238,855.1 miles.The maximum distance from the sun to the moon is 94,738,855.1 miles.
Therefore:The amount of time it takes for light to travel from the sun to the moon can beanywhere from 6.11862934 × 1016 hours to 6.35334516 × 1016 hours.
==============================================================
I have a couple of comments. Everybody else has already had a dip
in this pool, so I guess I can jump in too without getting hurt:
-- The first answer is a beautiful example of what happens when you put all of
your trust in your calculator or your computer. A truly amazing job of gathering
all the right numbers, and working through them for an answer, but he still made
a humongous mistake ... multiplying instead of dividing ... and he never caught it.
Why do you think that happened ? My answer is: No matter how complicated and
technical the problem and the process of solving it may be, the answer has to
satisfy your brain before you send it out there. That means you must stand back,
look at your answer, and ask "Does this answer make sense ?" Regardless of what
the calculator may say, your gut has to buy it. If your gut has no clue, then you're
at the mercy of your machines. That's a dangerous place to be, as you can plainly
see by looking back at the first answer.
-- The moon revolves around the Earth. So it's closer to the sun than we are for
half the time, and farther from the sun than we are for the other half of the time.
When you average that out, the moon is, on the average, exactly the same
distance from the sun as the Earth is, so it takes sunlight exactly the same length
of time to reach the Moon, on the average, that it takes to reach the Earth.
That's 8minutes and 20seconds . On the average.
-- The first contributor got wound up in his numbers, all with good intentions, and
ended up with kind of a mish-MASH. When it came to doing his final calculations,
he used severely rounded figures for the Earth's aphelion and perihelion radii,
(nearest and farthest distances from the sun), but then took the average value of
a number that gyrates wildly ... the moon's distance from Earth ... and wrote that
one to a precision of nine ( ! ) significant figures. His figure for the speed of light
in mph is right on.
-- I shall now commit a maneuver that will mark me as one of the lowest forms of
life in the Q&A world: I'll take the numbers that the first contributor collected with
so much toil, sweat, and tears, fix his little computational error, and present the
result as my own work.
Here I go:
Answer:Earth ranges from 91 million miles to 94.5 million miles from the sun.The moon is 238,855.086 miles from Earth.
The speed of light is 670,616,629 mph.
Therefore:The minimum distance from the sun to the moon is 91,238,855.1 miles.The maximum distance from the sun to the moon is 94,738,855.1 miles.
Therefore:The amount of time it takes for light to travel from the sun to the moon can beanywhere from 489.8 seconds to 508.6 seconds.
186,000 miles per second. This is the 'miles per second' that it takes light to get anywhere in a vacuum.
It takes right around eight minutes for sunlight to reach earth.
Using 238,900 miles as the distance to the moon the trip would take you about five months at 65 miles per hour. Now, imagine trying to reach the sun at 65 mph; the trip would take about 163 years.
Since sunlight travels at the speed of light, it takes about 8 minutes and 20 seconds for sunlight to reach Earth from the Sun. So, if the Sun sets at 5 o'clock, the sunlight reaching Earth at that time actually left the Sun about 8 minutes and 20 seconds prior.
When the Moon comes between Earth and the Sun, blocking the sunlight.
Triton is Neptune's moon. However, it takes about 155 min for sunlight to reach Triton.
It takes about 8 minutes and 20 seconds for sunlight to reach Earth.
It takes about 8 minutes and 20 seconds for sunlight to reach the Earth.

It takes about 3 days for a lunar module to reach the moon from Earth.
The normal time for a landing craft to reach the moon is approximately 3 days from time of launch.
According to my calculations 36 minutes
The moon's distance is 239,000 miles (384,000 kilometers).
