I cant find the article in my sky and telescope mag. but i read it yesterday anyway ill just post what i read In late november and early december the planets will be aranged in the sky in their natural order meaning, they will be on the epliptic in the order of mercury venus mars jupiter saturn uranus neptune and pluto. Of course you will not be able to see them all at once because of the elongation of the orbits but through out the night the planets will parade in this order backwards from east to west in the night sky. the article had some dates. i cant remember the dates that gave historcal significance of this event but when i find it i will post the dates. one was that this "pehenomena" of the planets hasnt happend in the sky seince the before the invention of the telescope. when i find the actual article ill post it in full.
