>>Why is this question even relevant?<<
This shows that you cannot manuver word-number values. They either fit or they don't. Thus the planet Neptune - that affected so much the Christian religion - was encoded in the Greek language. Thus thousand of years later when the planet was rediscovered and they were looking for a name for it they had to choose an only mythology name that agreed wich it's characteristics as seen from the telescope - blue in color, just like Uranus the Sky God is sky -blue in color.

Once again Oceanus(in the oldest spelling!) and Neptune encode the polar diameter of Neptune:

OOKEANOS = NEPTAN = PATER = 486

Kafre-Khufu center base distance = 486.877 m

Neptune polar diameter = 48682000 m

>>No, it wasn't known to anyone in ancient times, because it wasn't discovered until the 19th century AD ... we've just been through all that ...<<
Tons of evidence exists that it was known. It was simply rediscovered the 19th century.

>>No, it couldn't have been confused with a star because no one could see it which meant that no one knew it was there.<<
It could be seen with the help of telescopes and we know for a fact that the ancients used lenses to carry out astronomic observations.
