OK, so I've made a thread about this in the past I believe; not sure if it was on here or another site, but I wanted to ask Alien fans out there. Prometheus takes place on planet LV-223, but in Alien and Aliens, the planet is LV-426. Are these really two different planets (that I read from IGN, are right next to each other, which I am questioning), or do the names just change over time? 'Cause I was thinking, how could it be that the alien ship crashes back on the same planet, or at least that's what I believe happens, and yet it's also on LV-426? Does anyone know the real answer to this? Do you know what I'm asking? I was just thinking that the company (Weyland, or the then Weyland-Yutani) changes the name, but if not, there's something else entirely that I can only guess what happens. Also, I know I've been making a bunch of Prometheus threads, and I'm sorry if you're getting tired of it. I'm just really interested in the Alien franchise and am extremely excited for Prometheus.
