Planet Data

These data have been compiled from the data sources: NASA and solarviews.com


The Sun and Planets

Notes:
¹ mean distance from the Sun;
² angle between the planet's orbital plane and that of the Earth;
³ degree of ovalness in the shape of the planet's orbit.
Pluto is included here although it is not regarded as a true planet.

Satellites of the Planets

Notes:
¹ mean distance from the planet;
² angle between the orbital plane and the equatorial plane of the planet;
³ degree of ovalness in the shape of the satellite's orbit.
Only satellites of diameter larger than 80 km (50 miles) are included. "Irr" indicates an irregular shape.
