How long is a light year?

Question

How many feet/miles/yards??

Answer 1

A Light year is not a measure of time, no matter how it looks. It is a measure of distance. To be exact, it is the distance that light travels in a year, which is:

5,865,696,000,000 miles or
9,460,536,207,068,016 meters

ADDITIONAL DETAILS:
light travels at a speed of 186,000 miles per second

Answer 2

lets see. A nano second is about 1 meter. so 1 second is 10^^9 meters. A year is 365 days X 24 hours X 60 minuets X 60 seconds = 3.1536 X 10^^7 x 10^^9 = about 3 X 10^^16 meters

Answer 3

A light year is the distance light travels in 1 earth year, i.e, 3 exp 8 m/s * 60 s/min *60 min/hr * 24 hrs/day * 365 days/year * 1 year = about 9.46 exp 15 (9.46*10^14) meters long.

Answer 4

A light-year is defined as the distance that light will travel in a year. If the speed of light is 186,000 miles per second (300,000 km per second), then calculate the distance that light will travel in one year.

186,000 mi/sec x 60 sec/min x 60 min/hr x 24 hr/day x 365 days/yr

Answer 5

1 mile

Answer 6

The distance that a beam of light can travel within a year.

ex- When you turn on a flashlight, a beam of light travels from the end of the flashlight to the nearest obstruction (ex-a wall). If there was no obstruction, and the light continued to travel in that direction- how far it would travel in a year would be considered a light year.

Answer 7

Light travels approx 300,000 km in a sec.

Answer = (3600 x 24 x 365) x 300,000 km

Answer 8

The distance light travels in one year.

Answer 9

1 light years = 5.87849981 × 1012 miles
