1 AU is approximately 8 light minutes.
1 light year = 63,240 Astronomical Units
Light years and astronomical units are both units of distance.
-- the Astronomical Unit -- the Light Year -- the Parsec -- the Magnitude
A light year is much larger. 1 light year = 63,240 Astronomical Units
Betelgeuse is 40,473,416.93376 AU' (Astronomical Units) from Earth.
5.5 light hours is about 40 astronomical units (AU)
It depends on what it of distance is being used. A million million kilometres is 6684 astronomical units, which is the distance travelled by light in 3.3 million seconds, or 5½ weeks.
Units such as light years and astronomical units are useful because they can be used to measure very large distances without yielding extremely large numbers.
The scale used in space terms is often astronomical units (AU) for measuring distances within our solar system, light-years for interstellar distances, and parsecs for even greater distances in space. Astronomical units represent the average distance between the Earth and the Sun, which is about 93 million miles. Light-years are the distance that light travels in one year, roughly 5.88 trillion miles. A parsec is equivalent to about 3.26 light-years.
