Most Popular Stories. Just a Game? You Need a Chickadee Brain. Living Well. We can calculate this by multiplying the speed of light by 1 year or 3. Paul, MN This is a great question!
I especially like the way in which you asked it. When you ask such a question in relation to a light year both meanings are important! A light year is the distance between two points in space that it would take light to travel when the distance between the two points in time are one year.
Light travels at , miles every second! That is a huge number! If you were to write one number per second for eight hours a day without stopping to eat or to rest your hand it would take you six and a half days to get to number ,! And to think light travels that many miles in only one second!
Another way to think about how large this number is, is to think about how many times you could go back and fourth across the United States. If you go back and fourth across the US 66 times you will have traveled , miles. If you did this going an average speed of 60 miles per hour you will need one year and three weeks!
But light can do this same thing in one second! In one year there are days of 24 hours. How do you calculate the distance? How do you calculate light travel? How far does light travel in each time period? How fast does light travel? What is a light minute? How many hours is a light-hour? How many seconds is a light second? How do you convert light years to seconds? How long would it take to travel 1 Lightyear? How many light seconds away is the moon? How long would it take to walk to the moon?
How long does it take from earth to moon?
