Earth to moon . . . 1.28 seconds
Sun to earth . . . 8 minutes 19 seconds
The average distance from the Earth to the Moon is about 1.28 light-seconds. This means it takes light about 1.28 seconds to travel from the Earth to the Moon.
It takes about 1.28 seconds for light to travel from the moon to Earth. So if the moon were to travel at the speed of light, it would complete an orbit around the Earth in approximately 1.28 seconds.
About 1.3 seconds
It takes about 1.3 seconds since the distance between the Earth and the Moon is 230,100 miles and light travels 186,282 miles per second.
Roughly 1.28 seconds (rounded)
Light takes about 1.28 seconds to travel from the Sun to the Moon. This speed is approximately 299,792 kilometers per second, which is the speed of light in a vacuum.
It takes approximately 1.28 seconds for light to travel around the moon, which means the circumference of the moon is roughly 6,783 miles. Traveling at the speed of light, you could make a full trip around the moon in about 2.56 seconds.
1.28 seconds at the moon's average distance from earth ... same as for a radio signal.
A little less than one and a half seconds.
Approximately 1.28 light seconds away from Earth is the Moon. The average distance between Earth and the Moon is about 1.28 light seconds.
Laser light propagates at the same speed as radio waves or any other form of electromagnetic radiation. That is 186,282.4 miles per second. The moon averages about 239 thousand miles. Light, therefore requires roughly 1.3 seconds to cross the gulf dividing the earth and moon.
The average time that it takes for light to travel from the moon's surface to the earth's surface or vice versa is about 1.255 seconds.
