The term lightyear(s) has nothing to do with time. It is used as an unit to express astronomical distances, hence is more related to distances. 1 light year is the equivalent in distance to what light would travel in a year at the rate of approximately 186000 miles per second.
1,000,000,000 light-years (one billion light-years) are in one Gly
3.26 light years equals 3.08413226 × 10^13 kilometers.
440 light years = 2.58653992 × 1015 miles
A lightyear is not a measure of time but a measure of length that light can travel in 1 year. It would take 28 years for light to travel a lightyear
10 10ths is 1 - whether it is miles, milometres, micrometres or lightyears, or pounds, or people or anything.
There are 17500 years in 1 lightyear, so 17500x3= 52500 years for three lightyears.
It is approx 0.000015 light years.
It is around 640 lightyears away.
Estimated at about 2.5 million light-years.
Mercury Is 0.000131 lightyears away from earth
4.1 lightyears in the longer distance. 4.1 light years = 1.257 parsecs.
Its way less than 1 lightyear, so it's not counted in lightyears. Its about 3 light minutes depending on orbit
8 light years = 75685843780650 kilometers
Mars is 12.67 light minutes away from the Sun. That is 2.40937209 × 10-5 light years.
1 billion square lightyears
Depending entirely on the boundaries of the Solar System, it has been estimated to be a bout 2 light years.
10 light-years is 58,785,000,000,000 (58.785 trillion) miles.
