A light year is one where the extra cool blessings surpass the heartaches. 

A year when the sun does not set,,up there with the blue moon theory..>>>>>>>><<<<<<<<..

299,792,458 meters per second or 186,282 miles per second.

186,282X60 seconds=11,176,920 miles per minute.

X 60 minutes=670,615,200 miles per hour

X24 hours= 1.609476e+10 miles per day

and finally X 365 days= 5.874589e+10 miles per year

Light year ( In Astronomy ) The distance travelled by light moving in a vacuum in the course of one year at its accepted velocity of ( 299,792,458 Metres per second )

1 light year is the distance traveled by the light in 1 year through vacuum.

So, 1 light year = distance traveled by the light in 1 year

But, distance traveled = speed of light × time taken

= 3 × 10 raised to the power 8 × 1 year

But 1 year = 365 days = 365 × 24 hours = 365 × 24 × 60 minutes = 365 × 24 × 60 × 60 seconds

So, 1 light year = 3 × 10 raised to the power 8 × 365 × 24 × 60 × 60

i.e. 1 light year = 9.46 × 10 raised to the power 12 kilometer or 9.46 × 10 raised to the power 15 meter [Approximate value]

Now share the above information with your friends too.
