The reflected sunlight from the moon takes about 1.278 seconds to travel to the earth. The distance is about 384,000 kilometers at nearly 300,000 km/sec.
(Laser light from Earth that is bounced off the Moon has a round-trip of about 2.556 seconds.)
As the moon's orbit around the Earth is elliptical, the distance between the moon and the Earth varies.
When it is closest to the Earth (at Perigee), the distance is 363,104 km.
When it is farthest from the Earth (at Apogee), the distance is 405,696 km.
The mean distance is 384,399 km.
Please check the related link for a better idea of this concept. For the Earth's orbit around the Sun, the terms used are Perhelion and Aphelion instead of Perigee and Apogee.
As the Moon orbits our planet, it's distance varies from about 221,000 to 252,000 miles.
From a star to the Moon, it will take the same time it takes from the star to Earth. The Moon is only at a distance of about one light-second from Earth, and this distance is puny, compared to the distance to stars.
The closest star, of course, is our own Sun; distance is about 8 light-minutes (it takes light 8 minutes from the Sun to Earth).
The closest star after the Sun is Toliman (Rigil Kentaurus), at a distance of 4.3 light years. Star system, actually; the system consists of 3 stars; the one nearest to us is called Proxima Centauri.

Answer: In relation to distances out in space the moon is not far from Earth, so moonlight takes just less than 1/2 a minute to get here.
Answer: Just a little over a second. Light travels at 300,000 km/sec.
It take approximately 5 seconds for a strong laser to hit the moon and return to earth. __________________ It's less than that. The Moon's orbit averages 384,400 km from Earth, and the speed of light is 300,000 KM/sec. So the round-trip is closer to 2.4 seconds.
The time for light to travel from the Moon to Earth is about one and a quarter seconds.
Light travels through space at roughly 300,000 km/second, so the average distance between the Earth and the Moon (about 384,399 kilometers) is traversed in 1.28 seconds.
At the approximate perigee and apogee (356000 to 407000 kilometers), this will vary between 1.18 seconds and 1.36 seconds.
Since the moon's orbit is not exactly circular, and the gravitational attraction of the sun is quite strong around here,
the moon's distance from the earth varies quite a bit.
The published "average" distance is 238,855.7 miles (384,401 km).
At a speed of 186,000 miles per second, it takes light (or radio waves, which are also a form of electromagnetic radiation) about 1.5 seconds to travel the 250,000 miles to the Moon. The return trip will take another 1.5 seconds, so about 3 seconds for the round trip.
From a star to the Moon, it will take the same time it takes from the star to Earth. The Moon is only at a distance of about one light-second from Earth, and this distance is puny, compared to the distance to stars.

Roughly 2.5 seconds. Let's do the math:
The average distance between the moon's surface and the earth's surface is 380,500 kilometers(km). Light is an electromagnetic wave and travels at a speed roughly 3 x 10^8 meters/second(m/s) in a vacuum. Since distance = speed*time the time it takes for the laser pulse to travel from the the earth to the moon is, time = distance/speed. For round trip time = 2*(distance/speed). So the calculation is: time=2*(38500 x 10^3 m / 3 x 10^8 m/s) = 2.56 s.
-Light travels at 299,792,458 meters per second.-There is 31,556,926 seconds in one year.-Light travels 9,460,528,412,464,108 meters in one year and after doing the math, light travels 9,460,528,412,464.108 kilometers in one year.
Answer: 100,000 light years = 9.454e+17 km
how many light years the earth travels around the sunNo. The Earth travels around the Sun in a measurement of time called a year, which is one revolution or trip around the sun: approximately 584,020,178 miles.A light year is a measurement of distance that light travels in one year, which is approximately 5.88 Trillion (5,880,000,000,000) miles!
427.47 light years is the distance that light would travel in one year. Light travels at 186,000 miles per second. Multiply this times 60 seconds per minute times 60 minutes per hour times 24 hours per day times 365.25 days per year times 427.47 years to find miles.
Since the circumference of Earth is about 40,000 km, the calculation is 40,000 km / 24 hours = about 1700 km/h.
-Light travels at 299,792,458 meters per second.-There is 31,556,926 seconds in one year.-Light travels 9,460,528,412,464,108 meters in one year and after doing the math, light travels 9,460,528,412,464.108 kilometers in one year.
It is how many kilometers light travels in one year.
Answer: 100,000 light years = 9.454e+17 km

Light travels 31,536,000 seconds in a year, just like, let's say, a snail that never stops creeping. But light travels farther than a snail does in the same time. For example, in a year, light travels 9,454,254,955,000 kilometers (5,874,601,673,000 miles).
light travels 5,878,630,000,000 miles in a year.
Light travels 186,282.4 miles per second in the vacuum of space. At that speed, it takes the light from the sun about 8 minutes and 18 seconds to reach Earth.
I believe you mean "how far is the earth from the sun"? The mean distance of the Sun from the Earth is approximately 149.6 million kilometers (93.5 million miles), though the distance varies as the Earth moves from perihelion in January to aphelion in July. At this average distance, light travels from the Sun to Earth in about 8 minutes and 19 seconds.
4.2 light years. Which equals to... 8765.81 x3600 x 300,000 = 9,467,074,800,000 Kilometers away from Earth
427.47 light years is the distance that light would travel in one year. Light travels at 186,000 miles per second. Multiply this times 60 seconds per minute times 60 minutes per hour times 24 hours per day times 365.25 days per year times 427.47 years to find miles.
In spite of its name, a light year does not indicate time, but it indicates distance! It actually equates to the distance that light travels in one Earth year, which is a very big distance, seeing that light travels at 186,000 miles per second.
That would be an immense number. Light, itself, takes about 2.54 million years to go from Andromeda to Earth. (Or vice-versa).The number of kilometers is about 23 quintillion.
