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.
The Milky Way is about 100,000 light years in diameter and about 1000 light years thick.
If tectonic plates move at a rate of 2 cm per year, in 1000 years they would have moved a distance of 2000 cm, which is equivalent to 20 meters.
As far as light can travel
Well, imagine a bright beam of light joyfully hopping through space like a little firefly. In 1000 light years, that sweet light would travel a whopping distance of... 1000 light years! Just like a peaceful painter creating a masterpiece, light spread its glow far and wide in the vast universe.
167 light years
I think 2 light years. (1 light year=9.5 trillion km.)
The distance to the moon is about 1.3 light seconds or about 0.000000032 light years.
Not light years, 107 milllion km.
Approximately 4.2 light-years.
When we observe stars through a telescope, we are seeing light that has traveled vast distances to reach us. Since light takes time to travel these distances, we are essentially seeing the star as it was in the past. For example, if a star is located 1000 light-years away, we are observing light that left the star 1000 years ago, so we are seeing the star as it was 1000 years ago.
It travels approx 9.46 trillion kilometres.
