1 AU is approximately 8 light minutes.
1 light year = 63,240 Astronomical Units
-- the Astronomical Unit -- the Light Year -- the Parsec -- the Magnitude
Light years and astronomical units are both units of distance.
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.
Astronomical Units, parsecs, light years, take your pick.
Mercury--0.387 astronomical units Venus--0.723 astronomical units Earth--1.0 astronomical units Mars--1.524 astronomical units Jupiter--5.203 astronomical units Saturn--9.529 astronomical units Uranus--19.19 astronomical units Neptune--30.06 astronomical units Pluto--39.53 astronomical units Please note that these are all mean distances, and the actual distance will vary as to the location of the specific planet in its specific orbit.
