Edit: We have an official response! See Omni's explanation of how it really works here. Spoiler: It's actually 422.22 quadrillion possible planets. Ok I've seen a lot of people worry about sharing the same "universe" with everyone else. They seem to feel like their experience in Starbound will not be unique enough. Or that everything cool will have already been discovered. And quite frankly I just can't understand that. So I thought I'd give people some perspective. Based on this video the coordinates for planets are 8 digits each. 12345678 x 12345678 Now this could have changed, but using that as an example that gives us 10^16 or 10,000,000,000,000,000. 10 quadrillion possible planets. According to the preorder page 70,000 people have bought starbound already. I'm not sure if this includes the 4-packs or not. Just to be safe, we'll assume everyone bought a 4-pack. So 280,000 potential Starbound players. If the entire Starbound community wanted to collectively visit every planet at least once, each player would be responsible for visiting 35,714,285,714 planets. According to the video above, it takes about a minute for the FTL travel animation to complete. Lets assume we could shorten that to a single second. It would take 1131.74 YEARS for the ENTIRE 280,000 strong Starbound community to visit each planet if they worked 24/7. If we couldn't shorten the animation, it would take us 67,904.5 years. If we got all 7 billion people on the planet to play starbound that would still be 1,428,571 planets per person. If every planet visited creates a 1 kilobyte save file, the entire Starbound universe would require 9.3 EXAbytes of space (1 exabyte = 1 million terabytes). For reference you could store every word ever spoken by humans on 5 exabytes. Provided each person starts out in a random location, it is VERY likely that you will never *accidentally* visit the same planet as someone else. For all intents and purposes, each player will have his own 35 billion planet universe of his own. Honestly, if you could find a server that would support it, every Starbound player could play in the same universe and almost certainly never stumble upon anyone else. So yes. You will be sharing the same 16 quadrillion planets as everyone else, but provided you don't share your seeds on the internet, chances are, no one else has ever been to that particular planet. Now of course there are some caveats. Not every seed represents a planet. But I think we can all agree that the numbers are high enough here for that to not matter.
