How far is Neptune from the Sun?
Data as of July 2026
4,503 million kmfrom the Sun, on average
Neptune orbits the Sun at an average distance of 4,503 million km, which astronomers write as 30.1 AU (astronomical units, where 1 AU is the Earth to Sun distance). That is 30.1 times Earth's distance from the Sun.

Orbits are not perfect circles, so the number above is an average. Over one Neptune year the distance swings around that figure; the average is the one used in every table of the solar system, including the one below.
Sunlight covering that gap takes 4.2 hours (see how long light takes to reach Neptune).
Every planet's distance from the Sun
| Planet | From the Sun | AU |
|---|---|---|
| Mercury | 58.3 million km | 0.39 |
| Venus | 108 million km | 0.72 |
| Earth | 150 million km | 1 |
| Mars | 227 million km | 1.52 |
| Jupiter | 778 million km | 5.2 |
| Saturn | 1,433 million km | 9.58 |
| Uranus | 2,872 million km | 19.2 |
| Neptune | 4,503 million km | 30.1 |
On the scale where the Sun is a football, Neptune sits 707 metres away. Most diagrams cannot show that and quietly squash the gaps.
