A light year is much larger.
1 light year = 63,240 Astronomical Units
An astronomical unit is not larger than a light year. A light years is considered to be approximately 62,000 times larger than an astronomical unit.
kilometer, AU (astronomical unit), light year, parsec.
Three units are commonly used in astronomy - the astronomical unit; the light-year; and the parsec.
No. 150 million km is the distance from Earth to Sun, and this distance is called an AU (astronomical unit). Light travels this distance in about 8 minutes.A light-year is the distance traveled by light in a year, which of course is much more than the distance traveled in 8 minutes. A light-year is approximately 9.461 x 10 to the power 12 km.
No. A light year is the distance light travels in a year. By comparison, the sun is about 8 light minutes from Earth. This distance from Earth to the sun is called 1 astronomical unit or 1 AU.

See the Question "http://wiki.answers.com/An_astronmoical_unit_is_a_larger_distance_unit_than_a_light_yearQuote "One light year is about 63,200 AU. An astronomical unit is about 8 light-minutes."
kilometer, AU (astronomical unit), light year, parsec.
The light year by far. It is equal to about 63,241 AU's and each AU is about 93,000,000 miles (the distance from the earth to the sun). Over all a light year is close to 6 trillion miles.
-- the Astronomical Unit -- the Light Year -- the Parsec -- the Magnitude
Use "Astronomical UNit" or AU when discussing distances within the solar system. Use "light year" when talking about the distances between stars.
The astronomical unit is the mean distance from Earth to Sun. It is commonly used for distances in the Solar System. This way, it is easier to imagine the distances, since the meter or kilometer are very small units (an astronomical unit is about 150 million km, or 150 billion meters), and the light year and the parsec are very large units (a light-year is about 63,000 astronomical units, the parsec is even larger). Light-minutes or light-hours might be used instead, within the Solar System, but the astronomical unit has become quite popular.
