How much is light years?
A light-year is the distance light travels in a year. This is 9.5 x 1012 kilometers, which can also be written as 9,500,000,000,000 kilometers.
How much is 20 light-years?
A light-year is the distance light travels in one year, approximately 5.88 trillion miles. Therefore, 20 light-years would be around 117.6 trillion miles.
What is the diameter of Betelgeuse in light years?
Diameters of stars are not usually expressed in light-years. The term "light-year" is used for much larger distances. Its diameter is somewhere around a thousand times the diameter of our Sun, so that would be about 1.4 billion kilometers. Of course, you can convert that to light-years if you like.
How far is one quintillion light years?
If you want to convert that to kilometers, multiply the number of light years by 9.46 x 1012 (9.46 million million). Of course, a quintillion is 1018 in the USA and many other countries. So, that's 9.46 x 1030 kilometers. That's much much further than the horizon of the Observable Universe.
How many lightyears is the moon from the earth?
The moon is about 0.0000000406 light years away from earth. Clearly, the moon is MUCH too close (238,000 or 239,000 miles or so) for the distance to be rendered meaningfully in light years.
What is the size in square miles of the Universe?
First, you would measure the diameter of the Universe in miles, or its volume in cubic miles; but what would you want to measure in square miles?Second, the size of the Universe is not currently known. The observable Universe has a radius of about 46 billion light-years. Convert that to kilometers or miles if you like. One light-year is about 10 million million kilometers. But the entire Universe is probably much, much bigger.First, you would measure the diameter of the Universe in miles, or its volume in cubic miles; but what would you want to measure in square miles?Second, the size of the Universe is not currently known.

How much light does Colombia use?
69 light years
How many light years does it take for the earth to revolve around the sun?
Please note that a light-year is a measure of distance, not a measure of time - just in case you were confusing that. The distance Earth moves around the Sun is much, much less than a light-year. The radius of Earth's orbit is 150 million kilometers; multiply that by 2 x pi to get the circumference (since it's approximately circular). A light-year is 9.5 x 1012 kilometers; you can base your calculations on that.
How much time would it take to travel 40 light years?
Traveling 40 light years would take 40 years at the speed of light.
Earth travels around the sun in light years?
how many light years the earth travels around the sunNo. The Earth travels around the Sun in a measurement of time called a year, which is one revolution or trip around the sun: approximately 584,020,178 miles.A light year is a measurement of distance that light travels in one year, which is approximately 5.88 Trillion (5,880,000,000,000) miles!
How many light years is Eris from the sun?
Eris, the dwarf planet, is roughly 96 astronomical units (AU) away from the sun on average. This is equivalent to approximately 9 billion miles or 15 billion kilometers. In terms of light years, Eris is about 0.001 parsecs away from the sun, or approximately 0.00003 light years.
How much speed of light per seconde?
300,000 kilometers (186,282 miles) per second.
