Planets
NOTE: Unless otherwise noted, all names are unofficial.

Starting Planet
There are a few Fizzlits in this metallic planet, and two Bullet Bill blasters in the walls. There are some yellow platforms that disappear after a set amount of time. At the end of the planet, there is a glass sphere the player must break by making Yoshi eat Bullet Bills and spit them back out towards them. There will be a yellow and white platform, which the player will ride through the Gunner Path.

Gunner Path
This path is filled with Undergrunt Gunners and Mines. At the end of the path, the player will need to kill the Fizzlits and flip the switch to continue. The player will need to also use a Bullet Bill to break the glass sphere blocking the exit.

Bullet Bill Planet
There is a Hammer Bro on this planet, along with several Bill Blasters. The player will have to break the glass dome covering the lever so they can progress.

Airships
This path is much shorter than the Gunner Path. There are a few mines scattered along the path. During the player's travels, two Airships will appear, one with a ? Block and the other with a Hammer Bro and a Comet Medal. The player will need to shatter the glass sphere at the end of the path to progress.

Megahammer Planet
This is the planet where the player battles Megahammer. It is shaped like a green and white ring with a few Sling Stars and some black and yellow segments that fall off after Megahammer smashes its hammers against the planet or shoots a Banzai Bill at it. There are also some Star Bits around the top of Megahammer. There is a huge Black Hole in the center of the planet, however, Megahammer is not affected by it.

Trivia

 * This is the only Galaxy where Yoshi can be in the Grand Star victory pose without the use of glitches.
 * In the Italian versions of Super Mario Galaxy and Super Mario Galaxy 2, Bowser Jr.'s Airship Armada and this galaxy share the same name.
 * The battle with Megahammer in this galaxy and the battle with Bowser Jr. in Bowser Jr.'s Airship Armada are similar in that each features the use of a Sling Star during the battle. Incidentally, these two battles are the only situations between the two games in which a Sling Star may be used in a battle with either Bowser or Bowser Jr.
