Scale: 1 inch = 100,000 miles
--
On this scale the nearest star, Proxima Centauri,
would be about 4,000 miles away!
1 AU = 1
Astronomical Unit
= average (mean) distance between the Earth and the Sun
1 AU = 1.4960 × 1011 meters
= 9.2956 × 107 miles

The orbits of the planets are elipses, not circles, so the size reported here
is the semi-major axis, except for Pluto. The distance reported for Pluto
is the actual distance from the Sun in August 2022, and will be updated from
time to time.
