Including earth, how many planets were the ancient Greeks aware of?

Amazing that they were able to focus and determine all of them.

Saw Mercury for the first time very early in the morning...knew it wasn't Venus! Awesome, little silver ball!

They considered the moon a planet, and thus from there standpoint 7

Uranus is visible to the naked eye, but it's relative motion was not recognised by ancient astronomers

the Greeks has it going!! So very interesting!!
