The distance among each of the eight planets in our Solar System will alter depending on where each planet is in its orbit revolution around the Sun. Depending on the time of year the distance can also differ significantly.
The main reason for the planets to vary their distance is due to elliptical orbits. No planet in our Solar System orbits the sun in a perfect circle which means that the distance between planets is never the same. For this reason, to calculate the distance, we use the average to measure how far planets are from one another.
The Astronomical units (AU) column is the average distance between Earth and the Sun and is the most common way for scientists to measure distance in our Solar System.
Below is a table of the distances between each of the planets in our solar system.
