How big is the Ori galaxy's Human population?

[Daniel Jackson]

We know of the planet which features the village seen in a few episodes of SG-1. Then there's Celestus, which I thought was on the same planet until the movie proved otherwise. It seems there's no Stargates besides the Ori Supergate as indicated by an Alteran's journal of Stargate sketches from just before the Alteran cityship left. This has me wondering if these two worlds are the only worlds in the Ori galaxy populated by Humans. One for the Ori, and one for it's Human worshippors.

What do ya'll think?

It's never been explicitly established in the series, so we'll likely never know.

The closest we got to an estimate was when Vala mentioned in 'Crusade' that the Ori worshippers were constructing ships across dozens of worlds, although how she knew that for certain is unknown.

It's also possible that she might've grossly underestimated the number of inhabited worlds, since we saw Bra'tac make the same mistake when he stated in 'Lost City Part 1' that Anubis was sending the entirety of his forces to launch an assault on Earth, only for this to have been countered by Oshu in 'New Order Part 2' and evidenced in 'Reckoning'.

Also, it'd be kinda strange if their home galaxy truly only contained several dozen inhabited worlds unless it was a really, really miniscule galaxy to begin with since the Ori likely had millions of years (a head-start for that matter considering the time it would've taken the Ancients to travel to the Milky Way and establish themselves) to seed human life across their galaxy, and the Milky Way has at least several thousand inhabited planets. Add in the fact that the Ori would've very likely wanted to keep increasing the human numbers in their home galaxy as best they could, as it'd have meant more worshippers and therefore more power for them.
