Light cannot travel around the Earth, since light travels at a straight line and the Earth is round.
The speed of light is 300,000 kilometers per second.

The speed of light in a vacuum is approximately 299,792 kilometers per second (186,282 miles per second). Light can travel around the Earth's equator about 7.5 times in one second.

∙ 7y ago180,000 miles per second. That means since across the world is about 25,000 miles light travels around the world seven times in one second!
Wiki User
∙ 7y agoIt travels at a little less than 299,700 kilometres per second. However, near earth it travels in a straight line so it does not travel around the world.

For the moon to travel at the speed of light how long would it take to orbit the earth?
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.
How long does it take for light years to travel around the earth once?
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.
What is the equation for the travel time to the nearest star at the speed of light?
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.
How fast does light travel to Jupiter?
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.
What is the speed of light from sun to the earth?
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.
For the moon to travel at the speed of light how long would it take to orbit the earth?
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.
How long would it take to travel at the speed of light from Earth to Aldebaran?
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.
How long does it take to go around the earth at light speed?
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.
Has light originating outside of earth been tested for speed?
Light from stellar sources will travel at the same speed as light generated on earth.
Can Humans Travel at speed of light with no harm on earth?
No.
If nothing can surpass the speed of light in the Universe how is it possible that light on Earth can travel at the speed of light if Earth itself is moving at millions of km per second?
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 can anything else travel closer to the speed of light?
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.)

What speed dose earth travel around the sun?
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.
What is the amount of time it takes light to travel around the Earth seven and a half times?
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
Can a person travel at a speed of light?
No. Nothing with mass can travel at the speed of light.
