The distance between the Sun and the Moon isn’t constant because both bodies move in their orbits. However, we can estimate it easily.
🌞 Average distance from Earth to Sun
About 149.6 million km (93 million miles)
(This is called 1 Astronomical Unit.)
🌙 Average distance from Earth to Moon
About 384,400 km (238,855 miles)
📏 So what’s the distance between the Sun and Moon?
Since the Moon orbits Earth, the distance between the Sun and Moon is approximately:
-
About 149.2 to 150 million km
-
(Roughly 92.7 to 93.2 million miles)
The exact distance depends on:
-
The Moon’s position in its orbit (new moon vs full moon)
-
Earth’s position in its orbit (perihelion vs aphelion)
🌑 Fun fact
During a solar eclipse, the Moon is slightly closer to the Sun than Earth is — but only by about 384,400 km, which is tiny compared to 150 million km!
