Yes. Other units such as miles, kilometers or astronomical units are too tiny to be practical in discussing the distances between the stars, or between the galaxies.
One even larger unit is often used in astronomical measurements, the "parsec". This is the distance of one "parallax second of arc", and is approximately equal to 3.26 light years. For long distances across the galaxy, some astronomers use "kiloparsecs" as a unit of measure, and for intergalactic distances some astronomers use "megaparsecs" or "Mpc".
Light travels at a speed of 186,300 miles per second (299,821 kilometers per second). In the vacuum of space, over 1 year, light is calculated to be able to travel 5.9 trillion miles (9.5 trillion kilometers), thus 1 light year. It takes just over 8 minutes for light to travel from the sun to the earth.
Light travels at 299,792,458 meters per second, or about 670,616,629 miles per hour.
So in one week, light will travel a little more than 1.8 x 1011 km., or about 112.66 billion miles. (Think of the frequent flier points on that flight!)
To put that in perspective, the average distance from the Earth to the sun is defined as an astronomical unit (AU). In one week, light from the sun will cover 1,212 AU, just reaching the inner edges of the Oort cloud; by way of comparison, Pluto is only about 40 AU from the sun!
Correct. You can calculate that number quite easily. Light travels at about 186,000 miles per second, or 300,000 kilometers 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. Just multiply all those numbers together to get the distance of one "light year" in miles or kilometers.
Light travels at the speed of 186,000 miles per second. A light year is the distance light travels in one year. It takes 8 minutes for light to travel from the sun to the earth.
It gets it name because it is the distance that light travels in one Earth year.
A "Light year" is a distance. It's the distance light travels in one year, in vacuum.5,878,450,000,000 miles (rounded)9,460,450,000,000 kilometers (rounded)
900 billion years - if you travel near the speed of light. If you travel at any slower speed, it will take longer of course. But do some reading on time dilation - if the traveller travels at a speed very near the speed of light, from his point of view it will take much less time.900 billion years - if you travel near the speed of light.

It is a unit of length, not time. It is defined as the distance that light travels in a vacuum in one Julian year. It is just under 1013 kilometers or 6 trillion miles.Kilometers: 9,454,254,955,488 kmMiles: 5,878,630,000,000 milesSee related link for more information.
A light year is the distance light travels in one year, approximately 9.46 trillion kilometers. In contrast, a light minute is the distance light travels in one minute, which is about 17.99 million kilometers.
this can never change, light travels at a constant speed, a light year is the distance light travels in one year.
No, light year per hour is not a standard measure of speed. A light year is a measure of distance, not time. It represents the distance that light travels in one year.
Light travels at the speed of 186,000 miles per second. A light year is the distance light travels in one year. It takes 8 minutes for light to travel from the sun to the earth.
-Light travels at 299,792,458 meters per second.-There is 31,556,926 seconds in one year.-Light travels 9,460,528,412,464,108 meters in one year and after doing the math, light travels 9,460,528,412,464.108 kilometers in one year.
A light year is a unit of distance equal to the distance that light travels in one year. Light travels at approximately 186,282 miles per second, so in one year it covers about 5.88 trillion miles.
It gets it name because it is the distance that light travels in one Earth year.
# The distance that light travels in a vacuum in one year, approximately 9.46 trillion (9.46 × 1012) kilometers or 5.88 trillion (5.88 × 1012) miles.
a light year, the speed of light being 186,000 mph
Scientists don't measure the distance light travels in one year. They calculate it by measuring the speed of light. The speed is 300,000,000 meters/sec. and can be measured in the laboratory with a rotating mirror apparatus. To get the distance traveled by light in one year you multiply the speed (above) by the number of seconds in a year. The answer will come out in meters and is also called one light year.
That's the distance light travels in one year - about 9.5 x 1012 kilometers.That's the distance light travels in one year - about 9.5 x 1012 kilometers.That's the distance light travels in one year - about 9.5 x 1012 kilometers.That's the distance light travels in one year - about 9.5 x 1012 kilometers.
A light year is the distance light travels in one year. Light travels at 299792.458 km/s.
