Here are the average distances from the Sun to the planets in our solar system, rounded to the nearest million kilometers:

* Mercury: 58 million kilometers

* Venus: 108 million kilometers

* Earth: 150 million kilometers

* Mars: 228 million kilometers

* Jupiter: 778 million kilometers

* Saturn: 1.4 billion kilometers

* Uranus: 2.9 billion kilometers

* Neptune: 4.5 billion kilometers

Important Notes:

* Average Distance: These are average distances, as the planets' orbits are elliptical, not perfectly circular.

* Astronomical Units (AU): Astronomers often use Astronomical Units (AU) for distances within our solar system. One AU is the average distance between Earth and the Sun (150 million kilometers).

* Pluto: Pluto is now considered a dwarf planet. Its average distance from the Sun is about 5.9 billion kilometers.
