What is a astronomical unit?
One astronomical unit is the average distance from the Earth to the Sun, close to 149.6 million kilometers. Sunlight takes about eight minutes and twenty seconds to cross it.
The unit makes the solar system easy to picture. Mars orbits at about 1.5 AU, Jupiter at roughly 5.2 AU, and Neptune at about 30 AU. Beyond the planets, astronomers switch to light years and parsecs.
In writing, the astronomical unit is usually shortened to "AU". One astronomical unit is 149597870700 meters, and that ratio is what every figure on this page is built from.
