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

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.
