You can do the math:
the speed of light = 299 792.458 kilometers / second
1 year = 31 556 926 seconds
(31 556 926 seconds) * 299 792.458 (kilometers / second) = 9.46052841 × 1012 kilometers
That's it! You can get all the constants and conversions, and even do the math with Google.

∙ 13y agoLight travels at 299792.458km/sec so times that by 60 then by 60 again then by 24 then by 365 would equal 9454254955000.

What unit do you use to measure distance in your galaxy?
light years are used as a type of measurement to calculate the distance between planets, astronomical units are used to measure how far away a planet is from earth.
What is the distance to mercury from earth in cm?
The orbit of Mercury varies from 28,583,820 miles (46,001,200 km, 0.307499 AU) to 42,760,839 miles (68,816,900km, 0.466697 AU). That would be 4.9x 1012 cm to 6.8x1012 cm --- mean distance 5.8x1012 cm.
How far is center of milky way to earth in light years?
The milky way galaxy is roughly a disc shape the is around 1000 lightyears thick on average and 100,000 lightyears in diameter. Our solar system sits roughly 26,500 light years from the centre.
How far is the sun from the earth if the sun was scaled down to a golf ball?
In the scale in which the sun is the size of a regulation golf ball, Earth is the size of one medium grain of sand, and the distance between them is about 458 centimeters.
What earth minimum distance from sun?
The Semi-major axis. This is one Atronomical Unit (AU). The distance varies in practice though, due to the orbit not being a perfect and centralised circle. The perihelion is the shortest distance that a planet will be to the sun, the aphelion the longest.
Distance Gamma Hydrea is from earth?
The distance is 41 parsecs (approx 134 lightyears).
What is the distance to the second nearest star from earth?
it is 4.24 lightyears away
The distance between celestial bodies is usually measured in a unit known as?
Lightyears. The distance between the Sun and Earth is 1.49 lightyears (149 000 000 km)
How long is the distance from earth to the star Gemini?
over 9000 lightyears away
How many centimeters would represent the distance to a star that is 100 light- years from earth?
1 LY = 9.46089 x 1012 Km = 9.46089 x 1017 centimeters
How many lightyears is it from earth to the sun?
In terms of the speed of light, the distance between the Earth and Sun is81/3 light minutes,or about 0.00001585 light-year.
How much is 20 lightyears in earth years?
Lightyear isn't about time, it's distance. One lightyear is ten trillion kilometers.
How far is Qo'noS from Earth?
Two Lightyears
How many lightyears is the nearest star from the earth?
The nearest star to Earth is the sun, at a distance of 0.000016 light years from Earth. The next nearest star, Proxima Centauri, is about 4.2 light years away.
How far is Scheat from earth?
Approx. 196 lightyears.
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.
How long is the crux constellation?
The Crux or Southern Cross constellation is made up of four stars which can be joined in such a way, by an observer on earth, to make a cross shape. Although the smallest constellation, it is one of the most distinctive, appearing on both the New Zealand and Australian national flag. In the sky, it is not very long, maybe just as long as the width of the thumb at arms length. In real terms the distance between the top of the cross (a star called Gacrus) and the bottom of the star (Acrux) is huge. Gacrus is 88 lightyears from earth, while Acrux in over 320 lightyears from us, so a distance of about 230 lightyears separates them. The other two main stars in the constellation are around the same distance as Acrux, 353 and 364 lightyears.
