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.
One light-year is the distance light travels in one year, which is about 5.88 trillion miles. Light doesn't orbit the Earth, but if you're asking how long it takes light to travel around the Earth's circumference once, at the speed of light (about 186,282 miles per second), it would take only about 0.13 seconds.
The formula to calculate travel time at the speed of light is distance divided by the speed of light. The nearest star to Earth is Proxima Centauri, which is about 4.24 light-years away. Therefore, the travel time to Proxima Centauri at the speed of light would be 4.24 years.
Light travels at a speed of about 186,282 miles per second. The time it takes for light to travel to Jupiter depends on the distance between Earth and Jupiter, which varies as they orbit the sun. On average, light takes about 33 minutes to travel from Earth to Jupiter when they are at their closest approach.
The sun is roughly 8 minutes and 19 seconds away from earth in light speed!!! Imagine how far away it is in normal earth speed!?!? The speed of light is about 186,000 miles per second.
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.
It would take approximately 65 years to travel at the speed of light from Earth to Aldebaran, which is about 65 light-years away. However, currently, we do not have the technology to travel at the speed of light.
At the speed of light, it would take approximately 0.13 seconds to travel around the Earth. This means that a beam of light would circle the Earth almost 7.5 times in just one second at that speed.
Light from stellar sources will travel at the same speed as light generated on earth.
No.
I say millions because of the estimations I found for the speed of Earth around the sun, the speed of the solar system through the Milky way and the speed of the milky way through the universe.
What is the speed of light? About 300,000,000 meters per second - enough to travel all around the Earth 7.5 times in one second. Can anything travel nearly as fast? - Yes, in particle accelerators particles are regularly accelerated to over 99% of the speed of light. According to current scientific understanding: (a) it is not possible to transfer matter, energy, or information faster than the speed of light. (b) An object that regularly travels at a slower speed can't be made to travel at the speed of light - it can only approach it. (A photon, that is, a speed of light, can only travel at the speed of light.)

Earth travels around the sun at an average speed of about 67,000 miles per hour or 107,000 kilometers per hour. This fast speed allows Earth to complete one orbit around the sun in about 365.25 days.
speed of light = 299792458 m/s time it takes light to travel around the world = 40075160/299792458 = 0.134 seconds time it takes light to travel around the world 7+1/2 times = 1.005 seconds
Light travels at a speed of about 186,282 miles per second (299,792 kilometers per second). That means light can travel around the Earth about 7.5 times in one second! It's the fastest thing in the universe that we know of.
