“Though it can be seen with the naked eye, the realization that Uranus is a planet was a relatively recent one. Though there are indications that it was spotted several times over the course of the past two thousands years, it was not until the 18th century that it was recognized for what it was.”
Wasn’t astrology around in 2000 BC and didn’t they already know about all the planets ?
That’s what I was thinking. It should have been pretty obvious in the ecliptic plane?
