# Planets - Calculate Distances

Calculator for the average distances of the planets from the Sun and of the Moon from the Earth, in relation to each other or in kilometers, miles, astronomical units and light-years. An astronomical unit (au) is the average distance of the Earth from the Sun and is the most common unit for the distance calculation in the solar system. The distance of each planet from the Sun and of the Moon from the Earth is displayed in au, this unit can be changed in kilometers (km), miles (mile), or light-years (ly).

In the other fields, a value can be entered to calculate the ratios of the distances. If you enter e.g. a 1 at Jupiter, you will learn that its average distance from the Sun is 778299000 kilometers or 5.2026 times that of Earth.

 kilometers: miles: au: light-years: Distance to the Sun km mile au ly Mercury: Venus: Earth: Mars: Jupiter: Saturn: Uranus: Neptune: Pluto: Moon-Earth:

Round to    decimal places.

Please enter one value, the other values will be calculated.

Example for a calculation: Neptune is almost 78 times as far away from the Sun as Mercury.

The distances between two celestial bodies refer to the distance between their two centers at the semimajor axis of the elliptical orbits.

Our solar system has eight planets. Pluto is no longer considered a planet but a dwarf planet. It is included here, although its orbit is very elliptical, so the distance varies greatly. All the planets in our solar system have moons except for the two inner ones, Mercury and Venus. Earth's moon is special in that it is very large in relation to its planet. Moons of this size are otherwise only found on the gas giants Jupiter and Saturn.
The Oort cloud, a collection of small objects in the shape of a spherical shell, is believed to be in the outer region of the solar system. This could extend out into space for about 3.2 light-years or 200,000 AU. It is the source of long-period comets. © Jumk.de Webprojects | Online Calculators | Imprint & Privacy
