Citronis, the Yellow Planet
With far-spaced, thin rings and rotating on its side, Citronis is the true "Uranus" of the Persephone-1 system. Found with its sister planet Heliotropos, this gas giant follows a strange orbit, at times crossing into the latter's path and almost hitting it a couple of times. Eventually, that collision may yet come to pass...
Like the others, this pack features both ringed and non-ringed versions of Citronis for your game, and comes with an RPG maker tileset sheet.
Released for free Commercial and Private use, donations of course accepted but not needed.
Made with Photoshop 6.0
(Background not included -- it's just a quick mockup to show you what the planet looks like among something some-what space like. It's not all that pretty, in my opinon. I plan on releasing something far better in the future.)

More planets and stars. Like the universe?
Kinda more like a bunch of planets within a system at the moment. I just include the non-ring versions for those who want the planets without rings.
