The speed of light is 186 000 miles per second or 671 million miles per hour.
How far does light travel in a year. Multiply the number of seconds in one year by the number of miles or kilometers that light travels in one second and there you have it. A light year is how far light can travel in one year and is 9 461 10 12 km or 9 461 000 000 000 km. Light travels a whopping 9 460 528 000 000 km in a year equivalent to 5 878 499 562 555 miles. In the video you have a chance to see how far a lightyear is.
In one year 365 25 days that is equivalent to 5 869 713 600 000 miles. How far does light travel in 3 months. To obtain an idea of the size of a light year take the circumference of the earth 24 900 miles lay it out in a straight line multiply the length of the line by 7 5 the corresponding. One light year is about 6 trillion miles 9 trillion km.
As already noted the speed of light expressed in meters per second means that light travels a distance of 9 460 528 000 000 km or 5 878 499 817 000 miles in a single year. It s about 5 88 trillion miles 9 5. Your next goal then is to determine how many seconds there are in a year. A light year is a measurement of distance that signifies how far light travels in one year.
So how far does light go in a year. It really is an incredibly long distance a lightyear is roughly 6 trillion miles or nearly 10 trillion kilometers. When we use powerful telescopes to look at distant objects in space we are actually looking back in time. That is a 6 with 12 zeros behind it.
The distance light travels in a year is known as a light year and is calculated much the same way that the speed of one s motor vehicle is. Distance over time or d t. Then you multiply that by 3 600 seconds in an hour. To figure this out first understand that light s actual speed is measured as 186 000 miles per second.
Looking back in time. A light year is the distance light travels in one earth year. You start with the speed of light which is about 186 000 miles per second. Light travels at a speed of 186 000 miles or 300 000 km per second.
Those are really large numbers. Here s how you calculate it.
