Your question seems to suggest that you think a "light year"
is a length of time. It's not.
It's a distance ... the distance light travels in a year.
The distance is about 5,878,450,000,000 miles.
I cannot travel nearly that far in one year.
It will take 1 year, as soon as you and Albert work out how to travel at the speed of light. ;)
if you're asking "how long in years to travel 1 light year" you would have to know how fast you are traveling. a light year is a measure of distance that's equal to approximately six trillion miles...
1 light hour like how a light year is how far light travels in a year.
A light year is a value of measurement. It's how far light can travel in a year. One light year is approx. 9,500,000,000,000 kilometers (nine trillion five hundred billion km) ======================== Definition: 1 LY = 9.4605284 x 1015 meters
1 light year = 5,878,700,000,000 miles(rounded)
No. A light year is the distance light travels in a year, and nothing can travel faster than light. Therefore, the quickest that anything could travel a light year is 1 year. A comet travels much slower than light.
The information about a light-year is not relevant to answer this particular question. To find out how far light goes (in a vacuum) in any specific time, simply multiply 300,000 (km/second) by the number of seconds.
you cant light years refer to the distance light can travel in 1 year 1 Light Year = 5878625373183.61 Miles
LIGHT-YEAR (noun)The noun LIGHT-YEAR has 1 sense: 1. the distance that light travels in a vacuum in 1 year; 5.88 trillion miles or 9.46 trillion kilometersFamiliarity information: LIGHT-YEAR used as a noun is very rare.
1 billionth of a second 1X10^-10
if you are going the speed of light, it would take 1 year.
A light-year is a measure of distance, just like a foot, a meter or a mile. A measure of distance is not considered to travel. If the question is how far light travels in one second, the answer is 299,792.458 kilometers, or about 186,286 miles. The speeds noted refer to light moving in a vacuum.
