It is..more definition+ The astronomical unit (symbol au, or ua) is a unit of length, roughly the distance from Earth to the Sun. astronomical unit (AU): An astronomical unit (AU) is the mean distance between the center of the Earth and the center of the sun. The actual distance varies depending on the time of year, because the Earth's orbit around the sun is not a perfect circle. The mean, or average, separation is approximately 1.4959787 x 10 11 meters, which is Astronomical unit - a unit of length that is roughly equal to 150 million kilometers, the average distance from the Earth to the Sun. Other units of length used in astronomy are based on the speed of light and the time it takes light to cover a specific distance. The astronomical unit (symbol au, or ua) is a unit of length, roughly the distance from Earth to the Sun. However, that distance varies as Earth orbits the Sun, f..more definition+. A light-year (abbreviation: ly), sometimes referred to incorrectly as a light year, is a unit of length used informally to express astronomical distances.

Distances in the Solar System are easiest to describe in terms of the distance between the Sun and the Earth. This distance is called 1 astronomical unit, or 1 AU 

It is approximately equal to the mean distance between the Earth and Sun. The currently accepted value of the AU is 149 597 870 691 ± 30 metres (about 150 million kilometres or 93 million miles). An astronomical unit (abbreviated au) was a unit of length on the interplanetary scale, roughly equal to the (average) distance between Earth and Sol. One astronomical unit was equal to 150 million kilometers, or approximately 93 million miles.
