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.
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
-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.
Exactly 299,792,458 meters per second. Or about 9.461 times 10 to the power 15 meters in a year.
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.
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!
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 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
