Earth Sun Distance

The distance from the Earth to the Sun is one of the most fundamental measurements in astronomy. Serves as a standard unit to measure distances within the solar system.

It is defined as 1 astronomical unit (AU), which is approximately 149,597,870.7 kilometers or 92,955,807.27302553 miles.

Understanding this distance is easier with a simple online converter. Using our calculator, you can quickly convert any value in AU to miles, kilometers, or other units, making it simple to compare distances between planets, stars, and other objects in the solar system.

The Earth’s orbit around the Sun is slightly elliptical, so the distance varies throughout the year:

Perihelion (closest point): ~147.1 million km (~91.4 million miles)

Aphelion (farthest point): ~152.1 million km (~94.5 million miles)

Fun fact: light from the Sun takes about 8 minutes and 20 seconds to reach the Earth, so using the calculator helps visualize how far that distance really is in familiar units like miles or kilometers.
