How many kilometers are in 8.7 light years?

Answer 1

The answer of this question is at the end of the next paragraph if you don't want to know how I got it.

There are 60 seconds per minute, 60 minutes per hour, 24 hours per day, and 365 days per year. The speed of light is 186,000 miles per second. I'll show you the math that I did. 60 times 60 is 3,600. 3,600 is how many seconds are in an hour so multiply it by 24 to get how many seconds in a day which is 86,400 seconds. Then you would need to find out how many seconds are in a year so you multiply 86,400 by 365 and get, 31,536,000 seconds. Now that you know how many seconds are in a year all that has to be done is multiplying the speed of light by that number. 5,865,696,000,000 miles, or 5 trillion 865 billion 696 million miles are in 1 light-year. Since you want how many miles are in 8 light years you have to multiply 5,865,696,000,000 by 8. You get 46,925,568,000,000 miles.

Answer 2

To convert from light-years to kilometers, multiply by 9.5 x 1012.

Answer 3

Very far. About 50.4 trillion miles.
