Ancient Greek translation

Question

I'm not sure where to post this so I thought I would try here. Please let me know if there is a better place for this. I am creating a series of stories and there is some minor connections to nomenclature and myths of ancient Greece. This is a science fiction space series so the title I was looking to use was something along the lines of Stellar Era (age of space/stars). Based on some what I could find that dealt with ancient Greek, I came to: Aera Astrum. I hope to make this proper, so is this correct or is there a proper way to phrase this?

Thank you

Answer 1

In addition to Expedito's fine answer, you could make it a compound word, which I believe is quite idiomatic in Greek:

Asteraeon

This would mean something like "Star-Age".

Answer 2

I would translate it as Aeon Asteron (Αἰὼν Ἀστέρων).

According to LSJ, the Greek word αἰὼν (aeon), from which we get the the English word eon or aeon, has the meaning:

space of time clearly defined and marked out, epoch, age

The word for star is ἀστήρ (aster). The genitive plural form (= of stars) is ἀστέρων.
