Back when I was on the lore team, I was actually in the process of trying to do this stuff, trying to align the wacky shit of SS13 with some real world relatable science. I had a list of about 50 planetary systems and I was using SpaceEngine and reports from NASA and the ESA to detail everything about each planet. You can actually see leftovers of my efforts on the wiki, in the forms of the Altair, Sirius and Trimirti star systems still present on the quickbar thing.
I was also writing lore for some scientifically viable cloning, as well as for species like Vox and changelings, but apparently my rewrites were "too radical" and "way too detailed, nobody cares about all this stuff".
Oh, I'm also responsible for even giving Epsilon Eridani the time of day and actually making the planets of that system somewhat consistent, and renaming them.
