1. Light - year is an astronomical unit.

2. The asteroids all lie between 2.2 and 3.3 astronomical units from the sun.

3. AU Astronomers even use the astronomical unit which is the mean distance between the Earth and the Sun and they use light-years which is the distance that light travels in one year.

4. One astronomical unit is the distance between the Earth and the sun, about 93 million miles (150 million km).

5. Moreover, the star that exploded probably had a radius larger than 1 AU (astronomical unit, the Earth-sun distance)(/astronomical unit.html), which is larger than the orbits of the planets we see today.

6. Know astronomical unit and light year are used for expressing the distance between celestial bodies.

7. One astronomical unit is the distance between the Earth and the sun.

9. An astronomical unit is the distance between Earth and our sun.

10. One astronomical unit equals the distance from the earth to the sun.

11. One astronomical unit is equal to the average radius of the Earth's orBit, aBout 93, 000, 000 miles.

12. The distance from the sun to earth is one astronomical unit.

13. Most planet-formation models predict a “planet desert” within one astronomical unit (or the average distance from the Earth to the sun) of a host star.
