Green Stars?
Yes there are Green power stars in the game. Here is how to get them:
#1: Go to the Battle Rock Galaxy after you get Luigi's letter asking to go find him. he is where you found the first star. After you blast the cage with a Bullet Bill he will give you a green star.
#2: Go to the Buoy Base Galaxy swim under water and have the fish Bullet Bill break the glass with the pipe inside. Go in the pipe and have a Bullet Bill break the other glass and get the star.
#3: Go to the Dusty Dune Galaxy and do the 2nd star challenge. Somewhere you will find a hungry Luma. Feed it 20 starbits and it will transform into a new planet. Inside the planet you will have to get 5 transparent stars while the sand level rises and falls. When you get them all, the sand dissolves and the star is at the bottom.

20 Lives
Comet Observatory
If you havn't gotton all 120 stars with Mario, don't read this. When you start with Luigi, after you get a couple of stars, look for the mailtoad. He will be in front of the green steps. If you talk to him when he has mail, you get a letter addressed to Mario. Mailtoad addresses that problem, then gives you 20 lives. Awesome!

Hint: Enemy Sacrifice
everywhere
Hint: Enemy Sacrifice
This may be an obvious hint, but it's one worth stating nonetheless. When you fight most enemies, you can control what comes from their dead bodies when defeated (a sort of "sacrifice"). By jumping on an enemy, which is usually the more difficult way to kill most foes, a Coin will appear. Spin-killing or using other methods will usually result in a few Star Bits.

Rescuing Luigi
Haunted Mansion Galaxy
Go inside and beat all Boo's in the Haunted Mansion. Light is their weakness so look for a lit chandelier. Get a Boo mushroom and go past the bars. Inside, Luigi is locked up with a Boo on guard. Do not lose your boo form. Get the Boo to see you, (I hate romance) let it chase you, and then lead it to the chandelier light. If you lose your Boo form, it's alright, just get the Boo mushroom in the corner. Go past the bars in the cell Luigi's not in, and then lose your boo form. This is because Luigi's afraid of Boos. In your normal form, talk to Luigi. He'll give you a power star.

Bonus Planetoid
Dino Pirhana
When in Dino Pirahna (Good Egg Galaxy) Notice right when you land on the second planet with all the rolling balls there is a green platform up to the right. Jump on it but be careful, it shrinks when you step on it. Jump and kill the piranha plant and get into his pipe. You enter in a planet with many blue switches. Step on each one once to open up more switches do the same thing here. After you do it here there will be a launch star to take you to the next planet.

"Cosmic" Ground Pound
After learning the Star Spin
This is might be a move not discovered by most people, but it is easy to do once you master it. This move starts off by doing a spin in midair. Then you ground pound the moment you start spinning. Mario should plummet toward the ground with force slightly targeting a enemy landing on his feet with his hands in the air. This move doesn't do any extra damage but it was just a new move not mentioned.

Purple Comets
After you beat Bowser at the Galaxy Reactor and watch the credits, a message will say "The Purple Comet has appeared." Purple Comets make 100 (or sometimes 150) Purple Coins appear in the galaxy it is orbiting. Sometimes you are timed and sometimes you are not. These are the last 15 stars in the game and you should get them.

Flying Into Two Galaxies
Observatory Grounds
First, make sure you have unlocked the Sweet Sweet Galaxy (which is the pink Luma that takes starbits by the Terrace.) Next, get the power-up in the observatory that makes you fly. (Unlocked at the Gate.) Now, talk to the Luma that takes you to the Sweet Sweet Galaxy. Tell him you want to go to the galaxy, and he will become a launch star, and the galaxy's entrance will appear in the sky. Now, don't go into the launch star, but instead get the flying power-up, and you can actually fly into the galaxy without using the launch star. (Please note this only works for Sweet Sweet Galaxy and the Sand Spiral Galaxy.)
