- All dimensions are approximate, particularly those of the dwarf planets
- An Astronomical unit (AU) is 149,597,871 km (92,955,807 miles), Earth’s mean distance from the Sun
- Negative values of rotation period indicate that the planet rotates in the direction opposite to that in which it orbits the Sun (retrograde rotation)
