If you’ve ever spent hours warping between star clusters in No Man's Sky, scanning alien planets and picking up rare resources, you’ve probably wondered how many systems are in No Man's Sky. I’ve spent over 300 hours roaming the game’s galaxies, and I still haven’t scratched the surface of its total playable area. Part of the game’s massive appeal comes from its promise of near-endless exploration, but that endlessness can feel abstract when you’re trying to set exploration goals for your playthrough. This guide breaks down exactly how big the game’s system pool is, how it’s generated, and how you can make the most of your time exploring new systems.
How Many Systems Are in No Man's Sky, Exactly?
If you’ve ever looked up how many systems are in No Man's Sky before, you’ve probably seen the 18 quintillion number thrown around without much context. The short answer is over 18 quintillion procedurally generated star systems spread across 255 unique galaxies. That number sounds impossible to wrap your head around, so let’s put it in perspective: if you visited one system every second, it would take you over 570 billion years to see every single one. That’s longer than the age of the actual universe.
But that 18 quintillion number isn’t a random marketing gimmick. It’s a hard limit set by the game’s procedural generation algorithm, which uses a fixed seed to generate every system, planet, and creature consistently for every player. That means if two players warp to the same system coordinates, they’ll see the exact same planets, creatures, and resource spawns every time.
You don’t have to worry about running out of new systems to explore, even if you play the game every day for the rest of your life. For reference, most dedicated players only visit a few hundred systems over hundreds of hours of playtime, so you’ll never hit a point where you run out of uncharted territory to claim.
How No Man's Sky Generates Its Star Systems
I’ve tested this consistency myself by swapping between PC and console saves, and I always find the same glowing activated indium mine I set up in a rare blue star system three years ago on both platforms. The algorithm uses a combination of the universal game seed and each system’s unique coordinate set to generate every detail, from the color of the star to the behavior of the local alien traders.
Some key factors that shape each system include:
- Star type: Red, yellow, green, and blue stars each have different resource spawn rates, with blue stars holding the rarest high-value resources.
- Number of planets and moons: Most systems have between 3 and 7 celestial bodies, including barren rocks, lush habitable worlds, and toxic dead planets.
- Dominant alien race: Each system is controlled by either the Gek, Korvax, Vy’keen, or no race at all, which affects the types of missions and rewards you’ll find there.
- Sentinel aggression level: Some systems have peaceful sentinels that ignore you, while others have aggressive drones that attack on sight if you harvest resources.
This consistent generation is why players can share coordinates of rare systems with each other, and everyone who visits will find the same rare rewards waiting for them. You don’t have to rely on random luck to find a perfect habitable world or a high-value resource farm, as long as you have the right coordinates. That also means the 18 quintillion number is not inflated with duplicate systems, every single one is entirely unique.
Common Myths About No Man's Sky's System Count
Part of why people doubt how many systems are in No Man's Sky is that the number is so large it feels impossible. A lot of new players assume the 18 quintillion number is a lie, or that most systems are empty duplicates with no unique content. That’s not true, but there are some caveats you should know.
First, not all systems are accessible when you first start the game. You’ll need to upgrade your hyperdrive to reach green and blue star systems, and you’ll have to complete the main story to unlock access to the other 254 galaxies outside the starting Euclid galaxy. You won’t have access to the full pool of systems for your first 20 to 30 hours of play, unless you use a portal jump from another player’s shared coordinates.
Another common myth is that most systems are empty and have no interesting content. While you will run into plenty of barren systems with no habitable planets, every system has at least a space station, a few trade ships, and random events like pirate attacks or distress calls. I’ve found some of my favorite hidden bases and rare creature spawns in seemingly boring red star systems that I almost skipped over.
The last myth we should debunk is that you have to visit systems in order. You can warp to any system within your hyperdrive range at any time, or use portals to jump directly to any system in the galaxy as long as you have its 16-digit glyph address. You don’t have to work your way through every system between you and your target, which makes exploring far more flexible.
Tips for Tracking Your System Discovery Progress
If you’re someone who likes to track your exploration milestones, you don’t have to manually count every system you visit. The game has built-in tools to help you keep track of your discoveries, and there are a few tricks to make exploring more efficient.
First, check your Discovery tab regularly to see how many systems, planets, and creatures you’ve scanned and uploaded. You’ll get nanite rewards for every new discovery you upload, so it’s worth taking 30 seconds after warping to a new system to upload all your scans. These nanites add up fast, and you can use them to buy new upgrades for your ship, multitool, and exosuit.
Next, if you’re trying to visit as many unique systems as possible, set a small goal for each play session, like visiting 3 new systems and scanning all their planets. That makes the huge number of systems feel less overwhelming, and you’ll rack up discoveries faster than you think. You can also mark systems you want to return to with custom tags in your galaxy map, so you don’t lose track of rare resource farms or habitable worlds you want to build on later.
Don’t feel pressured to try to visit even a tiny fraction of all available systems. The fun of No Man's Sky comes from the quality of your discoveries, not the quantity. I’ve had more fun spending 10 hours exploring a single system with 4 lush habitable planets than I have warping through 20 boring systems in a row looking for rare resources. Play at your own pace, and don’t let the huge number of systems make you feel like you’re missing out.
At the end of the day, asking how many systems are in No Man's Sky is less about the exact number and more about understanding how much potential the game has for new adventures. Whether you’re a casual player who only logs on a few times a month to build bases, or a dedicated explorer trying to visit 1000 systems, you’ll never run out of new places to see. The game’s procedural generation system ensures that every playthrough feels unique, and you’ll always have a new surprise waiting for you around the next warp jump. If you haven’t explored a new system in a while, boot up the game, point your hyperdrive at a random star, and see what you find. You never know when you’ll stumble on your new favorite base location or a rare resource that lets you upgrade all your gear.
