* Most planets and dwarf planets rotate in the same direction that they revolve around the Sun. Negative values of the shown on this chart indicate that the or rotates in the direction opposite to that in which it the Sun. This is called retrograde rotation.

The distance from the Sun is given in units of the Earth's average distance from the Sun (93 million ). This distance is called an AU (). Looking at the chart, for example, you will see that Neptune is about 30 times more distant from the Sun than the Earth is.

Orbital periods are given in units of the Earth's one .

The eccentricity of a planet or dwarf planet's orbit is a number which measures how elliptical (oval shaped) the orbit of that planet or dwarf planet is. If the eccentricity of a planet or dwarf planet's orbit is 0, the orbit is a . Most planets and dwarf planets have eccentricities less than 0, so their orbits are elliptical.
