Super Mario 3D All-Stars: How to get all stars in Super Mario Galaxy

Planet of Trials

The small planet orbiting the Comet Observatory will be accessible once you've collected all three Green Stars. You'll get to it using a Launch Star near the Garage.

Navigate a rotating platform and spinning gears that you need to jump between and avoid being shoved off the edge by a large block. After the gears, you'll need to get through another set of platforms followed by a series of rails and ramps with speed boosts.

You'll land on a large gear followed by a beam with two large cubes. Get a Star Ball into the goal and you'll get the Power Star.

Collect five Star Chips to form a Launch Star to get you to a long path where a Bill Blaster is firing Bullet Bills. Navigate through them along with the floating mines and moving walls and you'll find another row of Bill Blasters. The Power Star is at the end of the path.

You have three minutes to complete a race on the back of a manta ray, navigating slopes, bends, and narrow paths plus a large loop in the middle. Succeed, and Coach Penguin will give you a Power Star.

Once you've already gathered 120 Power Stars you can complete one last mission by collecting 100 purple coins scattered around Toad Town and the castle garden. There are no enemies or obstacles so just enjoy the scenery!

All Stars in Super Mario Galaxy

Hopefully, this guide will help you complete your Super Mario Galaxy playthrough by collecting all 120 Stars. Of course, much of the challenge comes from actually mastering timing even if you know what you need to do, so these challenges might require a few tries. If you want help with Super Mario Sunshine or Super Mario 64, we also have guides for those games as well.
