How long would it take for an object traveling at the speed of light to circle the Earth?

If you could travel at the speed of light, you would be able to circle the Earth’s equator about 7.5 times in just one second! In other words, a light-second is the distance light travels in one second, or 7.5 times the distance around Earth’s equator. A light-year is the distance light travels in one year.

How long would it take to travel to the nearest star If you could travel at the speed of light?

Travel Time If Voyager were to travel to Proxima Centauri, at this rate, it would take over 73,000 years to arrive. If we could travel at the speed of light, an impossibility due to Special Relativity, it would still take 4.22 years to arrive!

How long would it take to travel at the speed of light?

So it would take 25,000 years to get there if you traveled at the speed of light. Actually, that’s the amount of time it would take from the perspective of the outside world. From the perspective of a traveler moving at the speed of light, it would appear to take no time at all.

How long would it take to travel to the Sun?

But if it could attain the record-breaking speed of Helios 2 ‘s close approach of the Sun – a constant speed of 240,000 km/hr – it would take 19,000 years (or over 600 generations) to travel 4.243 light years. Significantly better, but still not in the ream of practicality.

How long would it take to travel to the closest galaxy?

Thank you for you greatly, appreciated, time. The closest galaxy is the recently discovered Canis Major dwarf galaxy, which is “only” 25,000 light-years away. So it would take 25,000 years to get there if you traveled at the speed of light. Actually, that’s the amount of time it would take from the perspective of the outside world.

How long would it take to travel to Deep Space?

In short, at a maximum velocity of 56,000 km/h, Deep Space 1 would take over 81,000 years to traverse the 4.24 light years between Earth and Proxima Centauri. To put that time-scale into perspective, that would be over 2,700 human generations.
