The Solar System
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.

About RF Cafe RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived... |
