What is a light hour?

Question

(in words and in kilometers)

Answer 1

the distance light travels in one hour

Answer 2

How far light travels in an hour. A light year = 9.46 x 10^12 km. Using 365 days in a year, there are 365 x 24 = 8760 hours in a year. 9.46 x 10^12 ÷ 8760 = 1.08 x 10^9 km in a light hour

Answer 3

Bad question. A light hour is too long. However, you just need to take the speed of light and multiply by the number of seconds in an hour. ( 3600 * 300,000 )

A light nanosecond is easier to visualize. Just pick up a ruler. (Actually, light travels about 11.8 inches in a nanosecond, but that's pretty close to the length of a ruler).

Answer 4

The distance light travels in an hour.

We know the speed of light is 300,000 km/sec. so light travels 300,000 km in a second. And there are 60 seconds in a minute and 60 minutes in an hour, so do the math:

300,000 * 60 * 60 = 1,080,000,000 km.

Answer 5

Light hour or Light year?...Light-Year, in astronomy, unit of length sometimes used to measure vast distances. It is equivalent to the distance that light travels in a mean solar year. At the rate of approximately 300,000 km/sec (186,000 mi/sec), a light-year is equal to 9,461,000,000,000 km (5,880,000,000,000 mi)..

Answer 6

How far light travels in an hour

Answer 7

I figured this one out a while back while researching another question. In an hour light travels approximately 66 million miles so that's 66 million mph or (1,079,252,848.8 km/h).
.
Out fastest probe is traveling at 35,000 mph.

Answer 8

Jeez, Bob H, why didn't you take a light second (300,000 km) and multiply it by 3600 for a light-hour?

Answer 9

1.07925285 × 10^9 kilometers

I used google.
