and then there were... 9.
pluto is being 'demoted' to a non-planet, i hear.
i was struck by the fact that hindus have always talked about the nava-grhas, the nine planets including the sun, the moon, and the quasi-planets rahu and ketu. is it possible that indian astronomers created the quasi-planets 'rahu' and 'ketu' as mathematical functions to account for the discrepancies in the orbits of the then known planets (up to jupiter and saturn) -- which in fact were caused by the hitherto unknown uranus and neptune? any paleo-astronomers reading this blog?
