18 maj 2020 · One AU is the distance from the Sun to Earth's orbit, which is about 93 million miles (150 million kilometers). When measured in astronomical units, the 886,000,000-mile (1,400,000,000-kilometer) distance from the Sun to Saturn's orbit, is a much more manageable 9.5 AU.
Distances and scales To-scale diagram of distance between planets, with the white bar showing orbital variations. The size of the planets is not to scale. The astronomical unit (AU; equal to 150,000,000 km; 93,000,000 mi) is what the distance from the Earth to the Sun would be if the planet's orbit were perfectly circular.

Distances in the solar system are often measured in astronomical units (AU). One astronomical unit is defined as the distance from Earth to the Sun. 1 AU equals about 150 million km, or 93 million mi. Table below shows the distances to the planets (the average radius of orbits) in AU.
Astronomical unit, a unit of length effectively equal to the average, or mean, distance between Earth and the Sun, defined as 149,597,870.7 km (92,955,807.3 miles). The astronomical unit provides a convenient way to express and relate distances of objects in the solar system and to carry out astronomical calculations.
When Earth and the Sun are closest, they are about 147.1 million kilometers apart; when Earth and the Sun are farthest, they are about 152.1 million kilometers apart. The average of these two distances is called the astronomical unit (AU).
From an average distance of 93 million miles (150 million kilometers), Earth is exactly one astronomical unit away from the Sun because one astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. This unit provides an easy way to quickly compare planets' distances from the Sun.
