This table shows the values ​​of the orbits of the planets in the solar system: eccentricity, perihelion, aphelion. From these data, the semi-major axis is derived, which is the arithmetic mean of perihelion and aphelion. Also, the geometric mean, root mean square and harmonic mean of these points are displayed. Orbital values ​​are given in millions of kilometers (million km) or astronomical units (AU). In the table, you can also select the number of digits after the decimal point (other digits are rounded).

Data representation: millions km | a. e.

After the comma: 1 digit | 2 digits | 3 digits | 4 digits | 5 digits
