This data is from the
National Space
Science Data Center's Fact Sheet site. Click on a planet's name to
bring up the fact sheet at NSSDC. I have put together a list of links to
excellent tours of each planet. Click here to
bring up that list.

Notes: Mass is given in Earth masses (1 ME = 5.977 *
1024 kg);
diameter is the ``volumetric mean diameter'' that takes into account the planet's
oblateness; oblateness measures how much a planet bulges at the equator [= (equatorial
- polar diameter)/(equatorial diameter)]; distance is the semi-major
axis in astronomical units (1 A.U. =
1.496 * 108 km); rotation and revolution are the
sidereal rotation period and sidereal orbital period, h = hours, d = days;
eccentricity is the the orbital eccentricity = 1 - (perihelion/semi-major axis); inclination is the tilt of the orbit with respect to the ecliptic, and
axis tilt is the tilt of the planet's rotation axis with respect to its
orbital plane.
