Neptune’s orbital distance
Neptune’s orbital distance is the average separation between Neptune and the Sun.
How big is it?
30.11 AU away
Distance · rounded reference
A little perspective
About 4.62 times the diameter of Betelgeuse.
Betelgeuse: Betelgeuse is a red supergiant star in the constellation Orion that changes in brightness over time.

Neptune’s orbital distance
A rounded 30.11 AU semi-major-axis reference, not today’s distance.
Defined examples — our methodology
The marked distance is calibrated. Unmeasured illustration details are representative.
Betelgeuse
A deliberately rounded red-supergiant model. Its apparent edge varies with wavelength and the star changes over time.

Why this measurement?
Why we use 30.11 AU
For comparison, this page uses distance. This is labelled rounded reference: an explicit comparison model rather than a claim that every example has the same value.
A rounded 30.11 AU semi-major-axis reference, not today’s distance.
The marked horizontal span follows the named feature; transparent margins and unmeasured details do not alter it. How calibrated comparisons work →
