On a yahoo group posting the Pluto debate, this was an interesting, although Odd observation:
Why Pluto is a planet -
The clue is given to us using the Sun and the other two small planets. a) Mercury's orbital period is 28xpi (87.96) Earth days and we know that the Sun rotates in 28 days. Therefore Mercury orbits the Sun in pi (3.14) "Sun" days. b) Compared to Mars, Jupiter orbits the Sun in 2pi orbits of Mars. c) Also...Saturn is 2pi times further from the Sun than Mars. Mars orbits the Sun in 8^pi Earth days...687 days ! For certain...there's pi in the sky...!
And the best for last... Mercury...88 days Venus...225 days Mars... 687 days Total...1000 days !!!
1000 days in total, eh? Interesting, but it doesn't shed light about the other bodies farther out.
But still quite interesting.
