Roughly the average distance from the Earth to the Sun. Used for distances within our solar system. ### Mile (mi) An imperial unit of length equal to 5,280 feet or approximately 1.609 kilometers. The standard unit for road distances in the US and UK. ## Background The Sun is about 93 million miles from Earth. Mars at its closest approach is about 34 million miles (0.37 AU). Jupiter orbits at about 484 million miles (5.20 AU). American space coverage routinely uses miles alongside AU to make distances relatable to the general public. ## Good to Know 'Ninety-three million miles from the Sun' is one of those facts every American learns in school. It is arguably the single most repeated astronomical measurement in the English language, alongside the speed of light at 186,000 miles per second. ## FAQ ### How many miles are in 1 AU? One AU equals approximately 92,955,807 miles (about 93 million miles). This number is one of the most frequently cited facts in popular astronomy. ### How far is the Sun from Earth in miles? The Sun is approximately 92.96 million miles from Earth (1 AU). This varies from about 91.4 million miles (perihelion) to 94.5 million miles (aphelion) over the year. ### How far is Mars in miles? Mars ranges from about 34 million miles (55 million km, at closest approach) to about 250 million miles (401 million km, when on the opposite side of the Sun from Earth). In AU, that is 0.37 to 2.68 AU. ## Non-Frequently Asked Questions ### How many frequent flyer miles is a trip to the Sun? 1 AU is about 92.96 million miles. At typical airline loyalty rates of 1 cent per mile, that trip would be worth about $929,600 in rewards. Unfortunately no airline flies that route.
