Amount of distance in a light-year, in AU. Definition of astronomical unit. For general reference, we can say that one astronomical unit (AU) represents the mean distance between the Earth and our sun. An AU is approximately 93 million miles (150 million km).
Considering this, how long does it take to travel 1 AU?
How fast does light travel from the Sun to each of the planets? Light travels at a speed of 299,792 kilometers per second; 186,287 miles per second. It takes 499.0 seconds for light to travel from the Sun to the Earth, a distance called 1 Astronomical Unit.
Also Know, what distance is an AU?
about 150 million kilometers
Which unit is bigger 1 AU or 1 Ly?
A light year is the distance light travels in one year, while an AU, otherwise known as an astronomical unit, is the distance between the Sun and the Earth. A light year is approximately 9,500,000,000,000 km. An AU is 149,600,000 km. As you can probably tell, an AU is much shorter than a light year.
