Why were light years created?
Light years is a measurement of length (not time!), and was taken to use for the purpose of illustrating the wast distances in the galaxy and the universe. One light year is the distance in which light will travel during one year at the speed of Light ~3*10^8 m/s.
What is one light year unit?
It is the distance light travels (in a vacuum) in one year. 1 ly = (299,792,458 m/s)(60 s/min)(60 min/hr)(24 hr/day)(365.25 day/year) = N m/year This can be solved for N which is the number of meters light can travel in a vacuum (space) over the course of one year. <<>> The international definition of a light year uses a Julian year as the basis for the calculation, which is exactly 365¼ days, making the distance 9.46073047 times 10 to the power 15 metres.
What is refer by light year?
A light year is the distance which light will travel in a vacuum. Light travels at 299,792,458 m/s in a vacuum, one year is 31557600s (on average taking into account leap years) so 1 light year is 9.46073x10^15m or 9 460 730 473 000 km
What is the concept of a light yea?
I guess u r talkin about light year. It is referred to as the distance travelled at the speed of light for a year. means if an object travels at a speed of light(3*10^8 m/s) for a year, the distance travelled by it is known as 1 light year.
How long is a lightyear in miles?
A light year is a measure of distance, not speed. The word 'year' seems strange, I know. Asking 'how fast is a light year' is like asking 'how fast is a mile?' In a vacuum, light travels about 186,000 miles in one second. The moon is roughly 240,000 miles away, for comparison. So in one second, light from earth would make it most of the way to the moon! Now let light travel for one full year, and you could figure out how far that is. The distance would be called one light year.
What is the term for the distance light can travel in one year in a vacuum?
The distance light travels in one year is called a light year.It is approximately 6 trillion miles.9.4605284 x 1015 metresLight year is the distance traveled by light in one year. we just cannot imagine this. Because light travels 3*108 m/s. so just think how much it will travel in one minute, one day, one week, one month & one year.Exactly 9,460,730,472,580.8 (just under 9.46*1012) kilometers.
How many meters are there in twelve billion light year?
A light year is the distance light can travel in one year. Light travels at a speed of around 2.99*108 m/s. Multiplying that by the number of seconds in 12 years gives you 1.135*1017m.

What is one light year unit?
It is the distance light travels (in a vacuum) in one year. 1 ly = (299,792,458 m/s)(60 s/min)(60 min/hr)(24 hr/day)(365.25 day/year) = N m/year This can be solved for N which is the number of meters light can travel in a vacuum (space) over the course of one year. <<>> The international definition of a light year uses a Julian year as the basis for the calculation, which is exactly 365¼ days, making the distance 9.46073047 times 10 to the power 15 metres.

What unit do scientists mesure huge distance in space in?
A light year, which stands the distance light travels in a year's time, is roughly 1E16 m.

How many meters are there in 19.0 light -year?
Having "A light-year is the distance light (speed = 2.998 108 m/s) travels in one year," you will then find how many seconds are in a year (31,556,926 seconds), multiply that number by 19 (given). Once you get how many seconds total in 19 years (599,581,594 seconds in 19 years) you will then multiple that number times the speed (2.998 108 m/s).Final Answer: 1.798 x 10172med
One light years is equals to how many killometers?
It is a rather small fraction of a light year. A light year is about 9,460,730,472,580.80 km. The fraction of a light year that your number represents is roughly 5.9 divided by 9,461.
A light year is equal to?
Well depends.. If you're saying that the speed of light is 3x10^8 m/s then 1 light year is 9.46728x10^15 metres If the speed of light is exact (299,792,458m/s) then 1 light year would be 9,460,730,472,580,800 metres (9.46073x10^15) Not much difference...
What is the formula to find the distance of a light year?
The formula to find the distance of a light year is (speed of light) x (number of seconds in a year). The speed of light is approximately 299,792,458 meters per second, and there are about 31,536,000 seconds in a year. Multiplying these two values will give you the distance of a light year, which is approximately 9.46 trillion kilometers or 5.88 trillion miles.
