The astronomical unit is a unit of length approximately equal to the distance from the Earth to the Sun. The currently accepted value of the AU is 149,597,870,691 ± 30 metres, nearly 150 million kilometres or 93 million miles.
6.68*10^-12 au
1 Astronomical Unit = 149,598,000 kilometers.
AU and light-years are simply two different units of length, used in astronomy. The units are of different sizes. You can invent lots of other differences if you like, but basically, that's the difference - their size. Other differences might include how they are defined; and in what cases they are typically used.

A "length" is not a standard unit of measure.
1 AU, by definition.
== == Since 1 au is about 150 million killometer, 1 au is equal to about 150,000,000,000 meters.
Mercury--Sun= AU Venus--Sun= AU Earth--Sun=1 AU Mars--Sun= AU Jupiter--Sun= AU Saturn--Sun= AU Uranus--Sun= AU Neptune--Sun= AU Pluto--Sun= AU
The Earth is 1 AU from the Sun, not the diameter. See related question.
AU stands for Astronomical Unit. The Earth is 1 AU away from the sun. Therefore, 1 AU is approximately 93 million miles long.
1g AU = 1000mg Au 1 mole Au = 196.96655g Au 1 mole Au = 6.022 X 1023 atoms Au Calculation: 328mg Au x (1g Au /1000g Au) x (1 mole Au/196.97g Au) x (6.022 X 1023 atoms Au/1mole Au) = 1.00 x 1021 atoms Au
1 AU is 92,956,000 miles.
1 AU = 149,597,871 kilometers.
1 light year is approximately 63,241 AU. Therefore, 4.7 light years is about 297,116 AU.
The astronomical unit is a unit of length approximately equal to the distance from the Earth to the Sun. The currently accepted value of the AU is 149,597,870,691 ± 30 metres, nearly 150 million kilometres or 93 million miles.
The abbreviation for astronomical unit is AU. An astronomical unit is a unit of length roughly equal to the average distance from the Earth to the Sun, used to measure distances within our solar system.
Major axis of mentioned comet has length of 8 AU (1 AU at perihelion plus 7 AU at apohelion on the opposite side of Sun). According to Kepler's third law, the square of orbital period is directly proportional to cube of the orbit's major axis. When using astronomical units for distance and sidereal years for time, this simplifies to: T2 = a3, where T - orbital period a - length of major axis We can then calculate that T for a = 8 AU is about 22.62 years.
