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. ;)
To travel 1 light-year in distance, it would take exactly 1 year when traveling at the speed of light. This is because light travels at a speed of about 186,282 miles per second, so 1 light-year represents the distance light can travel in one year.
Light travels through space at a constant speed of about 186,282 miles per second, or about 671 million miles in one hour.
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 comet cannot travel a light year in one second. A light year is the distance light travels in one year, which is about 9.5 trillion kilometers. Comets typically travel at much slower speeds, so it would take a comet significantly longer than one second to cover that distance.
you cant light years refer to the distance light can travel in 1 year 1 Light Year = 5878625373183.61 Miles
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.
1 billionth of a second 1X10^-10
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.
if you are going the speed of light, it would take 1 year.
The question should be How Long is a light year (in standard form) as a light year is the DISTANCE that light will travel in one year No...I'm not sure what a light year would be in a leap year.
