About

This tool allows you to see the orbit of specific planets, moons and comets.

Click a link in the "See orbit" section at the top of the page, or go to the Space Section to see other orbits.

For planets the orbit around the sun is shown.

For moons, the orbit around the planet is shown.

The following data is sourced from Wikipedia for various planets, moons and comets:

Semi-major axis *
Eccentricity
Orbital period
Host star radius
Host star luminosity
Mass
Mean radius
Equatorial radius
Atmosphere Composition

From this data this tool calculates things such as:

The orbital diagram
Apoapsis / aphelion
Periapsis / perihelion
Visible Diameters of host star (e.g Sun visible diameter) at different positions of orbits
Total solar irradiance at different positions of orbits
Surface gravity at mean radius or equatorial radius
Equivalent heights to produce the same falling speed on Earth
Falling time for specific heights
Falling speed for specific heights

* Io and Europa semi-major axis simply calculated from average of periapsis and apoapsis.

If you have any questions about this tool or find it useful we would like to hear from you.
