Io, a moon of Jupiter, is not directly orbiting the Sun. Instead, it orbits Jupiter.

However, to answer your question indirectly, we can determine the average distance between Io and the Sun by considering Jupiter's distance from the Sun:

* Jupiter's average distance from the Sun: 778.5 million kilometers (483.6 million miles)

Since Io orbits Jupiter, its distance from the Sun will vary slightly depending on its position in its orbit around Jupiter. But, on average, Io is roughly the same distance from the Sun as Jupiter itself.
