Power Stars. They’re basically the heartbeat of the Wii’s most ambitious platformer. Honestly, when people think about Super Mario Galaxy, they aren't just thinking about the gravity-defying jumps or the way Mario’s feet clink against a glass planetoid. They are thinking about that chime. You know the one—the soaring, orchestral "ba-ba-ba-baaa!" that plays when you finally grab a Super Mario Galaxy star after a grueling boss fight or a precision-heavy platforming sequence. It’s a dopamine hit that feels earned, mostly because the game doesn't just hand them out.
Nintendo changed the formula here. In Super Mario 64, stars were often about exploration and "how do I get over there?" In Galaxy, the star is a reward for mastering physics.
The Different Flavors of the Super Mario Galaxy Star
Not all stars are created equal. You’ve got your standard Power Stars, sure, but the game gets weird with it pretty fast. Grand Stars are the big boys. You get these from defeating the major bosses like Bowser or his bratty kid, Bowser Jr., at the end of each galaxy cluster. These don't just add to your count; they actually power up the Comet Observatory, which is basically your hub world. It feels like you're actually repairing a ship. It's grounded. Well, as grounded as a magical space station can be.
Then you have the Prankster Comet stars. These are the ones that actually make people throw their controllers. Sometimes a comet swings by a galaxy you’ve already cleared, and suddenly everything is different. Maybe you only have one hit point (Daredevil Comet), or you’re racing a shadow version of yourself (Cosmic Comet). The Super Mario Galaxy star you get here isn't just a shiny trinket; it’s a badge of honor for surviving a high-stakes gimmick.

Hungry Lumas add another layer. You find these chubby little stars floating around, and they’re starving for Star Bits. You feed them enough—usually 400 to 1,600 bits—and they literally transform into an entire new planet or a sub-section of a level. It’s a bizarre biological quirk of the Mario universe that we all just kind of accepted in 2007. Once they transform, you can fly over to the new area and snag a hidden star.
Green Stars and the Completionist Nightmare
Most players finish the game with about 60 to 80 stars. That’s enough to beat Bowser and see the credits. But if you want the "real" ending? You need 120. And then, because Nintendo loves to watch us suffer, you have to do it all over again as Luigi.
Luigi handles differently. He’s faster, he jumps higher, but he slides like he’s wearing buttered socks. Getting every Super Mario Galaxy star as the green brother unlocks the final challenge: the Grand Finale Galaxy. This isn't just another level; it’s a victory lap through the Peach’s Castle festival from the beginning of the game. You collect the 121st star there. It’s a long road.
Why the Physics of the Star Matter
Gravity is the secret sauce. Most games have a "down." In Galaxy, "down" is whatever the nearest large object tells it to be. This means a Super Mario Galaxy star can be hidden on the underside of a platform, or tucked inside a hollowed-out sphere.
Koichi Hayashida, who worked as a level designer on the game, has talked about how they had to rethink everything for this title. They used "spherical walking" tech that allowed Mario to run around a 3D globe without falling off. This allowed the developers to hide stars in ways that were literally impossible in Super Mario Sunshine or 64. You aren't just looking left and right; you’re looking "out" into the orbit.
- Launch Stars: These are the orange, star-shaped anchors that sling you between planets.
- Star Chips: Sometimes you have to find five little pieces to make a Launch Star appear.
- Silver Stars: Collecting five of these in a single area spawns a Power Star. It’s a classic scavenger hunt.
It’s worth noting that the "Pull Stars" are a standout mechanic. These are small blue stars that Mario can grab onto using the Wii Remote's pointer (or the gyro/touchscreen in the Switch 3D All-Stars version). You basically zip-line through space. It feels tactile. It feels like you’re actually interacting with the cosmic fabric.
The Emotional Weight of Rosalina and the Lumas
We can't talk about the Super Mario Galaxy star without talking about the Lumas. These are the star-children that follow Mario around. One of them actually lives under his hat! This Luma gives Mario the "Spin" move, which is the most important mechanic in the game. It’s an attack, a jump extender, and a way to activate switches.
The lore here is surprisingly heavy for a Mario game. If you go to the Library in the Comet Observatory, Rosalina reads you a storybook. It explains that Lumas eventually turn into stars, planets, and even entire galaxies. When you collect a star, you aren't just grabbing a trophy. You’re essentially interacting with the life cycle of the universe. It gives the whole "collect-a-thon" genre a weirdly spiritual undertone that Nintendo hasn't really revisited since.
Real-World Impact and Legacy
When Super Mario Galaxy launched, it was a technical marvel. The Wii wasn't a powerhouse. It was basically two GameCubes duct-taped together. Yet, Nintendo EAD Tokyo managed to make the stars glow with a bloom effect that looked "next-gen" even compared to the Xbox 360.
Today, you can find the Super Mario Galaxy star in various forms of merch, but its real legacy is in game design. Super Mario Odyssey took the "crazy" ideas from Galaxy and turned the dial to eleven, but it lost some of that tight, focused challenge. In Galaxy, the star is the end of a path. In Odyssey, Moons are everywhere—under rocks, in crates, behind bushes. There’s something more prestigious about the Galaxy star. You see it at the end of the tunnel. It’s glowing. It’s waiting.
Common Misconceptions About Collecting Stars
One thing people get wrong is thinking you need to be a pro at the motion controls to get every Super Mario Galaxy star. You don't. While the Wii version relied heavily on the sensor bar, the Super Mario 3D All-Stars port on Switch allowed for much more flexibility. You can use the touchscreen in handheld mode to collect bits, which is honestly way faster.
Another myth? That the "Luigi 120" run is just a reskin. It’s not. The dialogue changes. NPCs react differently to him. Some stars are actually harder to get because of Luigi's friction (or lack thereof). If you haven't done the full 242-star grind (including the second game), you haven't seen the peak of 3D platforming.
Actionable Tips for Completionists
If you’re dusting off your Wii or booting up your Switch to hunt down every last Super Mario Galaxy star, keep these specific strategies in mind. They’ll save you a lot of "Game Over" screens.
First, master the "Long Jump to Spin" combo. If you long jump and then shake the controller at the apex, Mario gets a tiny bit of extra height and distance. This is essential for skipping some of the more tedious moving platform sections. Second, don't ignore the Star Bits. You might think they’re just for show, but they’re your primary currency for the Hungry Lumas. Always keep a bank of at least 500.
Also, pay attention to the shadows. In a game with wacky gravity, your shadow is the only thing that tells you exactly where you're going to land. If you're aiming for a star on a tiny floating platform, look at the shadow, not the character.
Where to Look for Help
If you’re stuck on a specific trial—like the infamous "Luigi’s Purple Coins" in the Toy Time Galaxy—you aren't alone. That level is widely considered one of the hardest in Mario history. The trick is to never stop moving. The tiles disappear behind you. Don't try to get every coin. You only need 100 out of 150. Focus on a path that circles back to the start.
For those wanting to dive deeper into the development, the Iwata Asks interviews are an incredible resource. Yoshiaki Koizumi and the team go into detail about how they designed the gravitational pull of the stars. It’s a masterclass in game design that still holds up nearly two decades later.
Collecting every Super Mario Galaxy star is a rite of passage for platforming fans. It’s a journey that takes you from the center of a volcano to the literal edge of the universe. Whether you're doing it for the first time or the tenth, that feeling of flying through the vacuum of space toward a glowing yellow beacon never gets old.
To make the most of your next playthrough, start by focusing on the "Secret Stars" hidden within the normal missions. These often require you to feed a Hungry Luma that appears mid-way through a level you've already visited. By knocking these out early, you avoid having to backtrack through the entire galaxy map later in the game. Keep your Star Bit count high, watch the comet schedules on the hub world map, and always look for the sparkle of a hidden path tucked just out of sight.
