The distance between planets in our Solar System varies depending on where each planet is around the Sun in its orbit. The distance can also vary considerably depending on the time of year.

An Astronomical Unit (AU) is basically the average distance between the Earth and the Sun.

So an AU is approximately 93 million miles or 150 million kilometers.

Distance between planets and other heavenly bodies in our Solar System is measured in Astronomical Units (AU).

## Distance Between Planets of the Solar System

It is because of the constantly changing distance between them we use the average distance to determine how far planets are from each other and to calculate the distance.

The astronomical Unit (AU) is the total distance between Earth and the Sun and is the most common way in our Solar System for scientists to calculate distance. 1 AU is the distance from the Sun to Earth, which is 149,600,000 km.
