As far as light can travel
In vacuum it will travel approx 57 trillion kilometres.
About 2.93924991 x 1013 Miles
Well, it takes 2,700 years for light to travel that far. Anything travelling at half light-speed would take 5,400 years. At 1/4 light-speed, it would take 10,800 years.
How far does light travel in one hour
Infrared light can travel through a vacuum and is limited by the strength of the source and the sensitivity of the detector. In space, infrared light from distant stars and galaxies can travel vast distances, enabling astronomers to view objects billions of light years away. On Earth, atmospheric absorption limits how far infrared light can travel.
This varies widely, between about four light-years for the nearest star (after the Sun, that is), to billions of light-years for stars in the farthest observable galaxies.
Toliman (Alpha Centauri) is at a distance of 4.3 light-years. That means it would take a ray of light 4.3 years to travel from here to Toliman, or from Toliman to here.
Light travels at approximately 186,000 miles per second. By multiplying that amount by 60 it gives you the distance light travels in one minute. Multiply that figure by 60 and you get the distance for one hour. Then multiply by 24 to get the distance traveled in one day. Multiply that by 365 for one year then by 1000 to see how far light can travel in 1000 years. So, light traveling at approximately 186,000 miles per second, in 1000 years can travel a staggering...5,865,696,000,000,000 miles. That is nearly 6 quadrillion miles! There is also a unit of distance designed especially for light (but can also be used for other things) called a 'light year'. A light year is how far light can travel in one year. Therefore in 1000 years, light can travel 1000 light years.
A 'light-year' is a distance calculated by how far light can travel in one standard year. A 'light-minute' is how far light can travel in one minute. Earth is about 8 light-minutes (93,000,000 miles) from the Sun. 14 light-years in space is going to be about 84 trillion miles, a huuuuge distance!
The star won't normally "travel the 37 light-years to Earth". 37 light-years would most likely be the distance from the star to Earth; it takes light from the star 37 years to reach us. Please note that a light-year is a unit of distance; it is NOT a unit of time. To convert from light-years to kilometers, multiply the number of light-years by 9.5 x 1012.
There are more things for the light waves to bounce off of in water, so light can not travel in a straight line or as far.
