Algodoo

All of the orbits in this scene are circular, but in real life, I believe they are elliptical (except for Mercury, which is a special case). I'm not an astronomer, so you may need to confirm what I am saying here.

yes dude! i know. and id love to have the algadoo know how to do eliptical movement on here. so ive gone for diagramatical view. was focusing more on trying to get the orbit times right. ie saturn going round once every 29 orbits of earth ect. even that was tough! im i rookie! anyway an eliptical path would cause a massive fluctuation in the tacheon feild rupturing spacetime and if my calculations are correct that would allow an infinate amount of multiverses to occur! and in one of those multiverses there would be a universe almost identical to ours but the planets would orbit in an eliptical manor! in this universe i win the debate!!

anyway if you know if its possible to tune this up to do eliptical movement please be my guest. as i said im learning the package.

not eliptical!!!! i meant CIRCULAR!!!! lol

Wait half a minute! Something's not right with this model! You forgot the last planet - Pluto!!!

pluto no longer classed as a planet! we was lied to dude! lol
