Do all the planets follow roughly the path of the old 12 zodiac constellations in the sky?
all previous answers have missed out that neptune has an eccentric orbit, the other 7 planets and pluto all orbit anti-clockwise in the same plane and pass throught every constellation, but neptune was hit hard by a large object a few billion years ago and goes clockwise in a alightly different plane so does not pass through all the constellations in every neptunian year
