How far is 12. 2 light years in miles?

Answer 1

A light year is the distance that light travels in one Earth year. It's not a measure of time,

but of distance.

Light travels 299,792,458 meters per second in a vacuum (in space). In one year,

light travels 9.46 x 1012 kilometers. (Unless it bumps into something and gets absorbed.)

Answer 2

Almost incomprehensibly far. It equates to a number so large it is best expressed as: 7.64204976 × 1022 miles.

This means even if you could somehow travel at the speed of light the entire distance, it would still take you 13 billion years to arrive there!

It's also approximately one-third the distance to the edge of the observable universe, if that puts it into better perspective.

Answer 3

That's easy, but your basic 4-function calculator will choke on numbers that big.

13,200,000,000 times 186,000 times 60 times 60 times 24 times 365.24.

Light travels at 186,000 miles per second. There are sixty seconds in a minute, and 60 minutes in an hour. There are 24 hours in a day, and 365.24 days per year.

Answer 4

Light travels at 186,000 miles per second.

There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365.24 days per year.

Thirteen billion is 13,000,000,000.

Just multiply all those numbers together.

Answer 5

Light travels at 186,000 miles per second. There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365.24 days in a year.

So 186000*60*60*24*365.24*139 =

Did you know that you can use Google as a calculator? I pasted this equation into the search box in Google and got:

Answer 6

I've been seeing this question for several days now and it's been irritating me. Have you people

never heard of Google calculator? You go to Google and type in "13.2 billion light years in miles"

and it tells you the answer, right at the top of the search results page. To insane precision;

that should really be "7.76" because you've only got three significant figures, but the

point remains: simple unit conversion problems can be answered much easier and faster

on Google than here.

13.2 billion light years = 7.75961975 × 1022 miles

But you didn't post the question to get an answer. The answer is of no use to you.

Much more likely that you posted the question in order to see a huge, cool number.

So stand back ... here it is:

13.2 billion light years = 77,596,197,500,000,000,000,000 miles (rounded)

Answer 7

A lightyear is actually a unit of distance not time. In which case the answer would be 5.88 trillion miles. That's the distance that light will travel in one year in space


If a human would try to travel a lightyear in the average speed of a space shuttle, say 14000 miles an hour, it would take almost 49,000 years on Earth. If you walked at 1 mph nonspot, it would take 572 million years, or 5 million lifetimes.

I'd stay on earth if I was you...

Answer 8

A light year is the distance light travels in a year.

So it will take 13 billion years for light, which does not deviate from its path, and does not pass through a thicker medium, (only in vacuum), to travel 13 billion light years.

Answer 9

If c = 299792458 m/s

and a year is : 31536000 s

a light year will be after conversion and calculation = 5,878,625,373,183.608 miles

0.42 of the prev. number is 2,469,022,656,737.11536 miles

So if we add them we'd get 8,347,648,029,920.72336 miles

The speed of light is generally regarded as 186,000 miles per second, so just multiply that by 60, 60, 24, 365, and 1.42 and you have your answer.

Answer 10

I'm not sure that the answer, in miles, kilometers, or furlongs, would mean anything useful. If physics as we know it has been relatively constant (assumed, but NOT proven!) then that distance would be the distance back to the Big Bang.

You can do the math yourself; light travels at 186,000 miles per second, or 300,000 km per second. There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365.24 days in a year. Just multiply all those numbers together.
