Discovery by whom? Surely not Galileo. His best telescope was under 100X
and was plagued by chromatic abberation. It is unlikely Galileo could
have readily identified a planet past Jupiter as a planet. His equipment
was just too crude. Secondly he could not have deduced the existence of
planets further out since had had no gravitational laws.
As it was in the 1930's Pluto was spotted more or less by luck and then
only because of modern blink type viewers that could spot a movement.
