The relative orbits of our sun and nine (er... make than eight planets, plus the
former planet , Pluto) planets is shown here. There is an asteroid belt that lies midway between the orbits of
Mars and Jupiter. Pluto, Ceres and Eris are known formally as minor planes because their sizes do not qualify them
are full-fledged planets. Pluto was demoted from its planet status by the
IAU in 2006. All of the planets lie within a few degrees of the "ecliptic plane," as can be seen in the
image below. All planets except Uranus have their axis of spin oriented relatively perpendicular to the ecliptic
plane. Uranus' spin axis lies roughly in its direction of its orbital path around the sun. Please contact
me if you would like a higher resolution version for your project or report.
