Light travels approximately 9,460,706,958,078,329 meters in one year.
That is the distance. You can also write in in scientific notation as 9.46 x 1012 km, or 9.46 x 1015 meters.
Exactly 299,792,458 meters per second. Or about 9.461 times 10 to the power 15 meters in a year.
The speed of light is about 300,000 kilometers per second (3 x 108 meters per second); the distance light travels in a year is called a light-year. It is equivalent to about 9.5 x 1015 meters.
-Light travels at 299,792,458 meters per second.-There is 31,556,926 seconds in one year.-Light travels 9,460,528,412,464,108 meters in one year and after doing the math, light travels 9,460,528,412,464.108 kilometers in one year.
A light year is the distance light will travel in one year, a light minute is the distance light will travel in one minute.The speed of light is 299 792 458 metres per second.In one minute light will travel 60 x 299 792 458 = 17 987 547 480 metres.
1 light year = 9.4605284 × 1015 meters
Exactly 299,792,458 meters per second. Or about 9.461 times 10 to the power 15 meters in a year.
A 'light-year' is a distance calculated by how far light can travel in one standard year. A 'light-minute' is how far light can travel in one minute. Earth is about 8 light-minutes (93,000,000 miles) from the Sun. 14 light-years in space is going to be about 84 trillion miles, a huuuuge distance!
In a vacuum, light always travels at the same speed, approximately 3 x 10^8 meters/second. In a year, there are 31556736 seconds, so light travels 9.5 x 10^15 meters. That unit is called a light year. More details are available at: http://en.wikipedia.org/wiki/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.
Scientists don't measure the distance light travels in one year. They calculate it by measuring the speed of light. The speed is 300,000,000 meters/sec. and can be measured in the laboratory with a rotating mirror apparatus. To get the distance traveled by light in one year you multiply the speed (above) by the number of seconds in a year. The answer will come out in meters and is also called one light year.
A light year is a measurement for distance; It is calculated by multiplying the number of seconds in a year by the distance light travels in 1 second ( which is roughly 300,000 Km). So something like 300,000,000 * 60 * 60 * 24 * 365 = 1 lightyear in meters * 60 to get to minutes, again * 60 to get to hours, then * 24 to get to days and finally * 365 to get to the distance light travels in 1 year.
