Space Junk Galaxy

The Star Junk Galaxy is a galaxy in the upcoming game Super Mario Galaxy. This Galaxy has a futuristic/space theme. A lot of the objects are silver or blue, and there is a spaceship in it.

The Float Star is used much more than in other known galaxies. Also Toads are on a big platform covered in crystals; if Mario frees the Toads trapped in the crystals a Mushroom-shaped spaceship will appear to take Mario to the next location. There is also a wooden planet shaped like Yoshi's head.

The last unique feature of this galaxy is that it has a path that builds itself when Mario approaches it, but crumbles after he leaves.

Mario fights two bosses in this galaxy: Tarantox and Kamella.

Crystal Planet
The Crystal Planet is a planet in Super Mario Galaxy that is encountered shortly before the battle with Tarantox.

At first, Mario walks on top of it, which is practically a transparent crystal orb. Once he finds the passageway in, he can go under the crystal layer and explore underneath, where 1-Up Mushrooms and other treats are waiting. There are also a few Space Rabbits underneath the crystal layer, who guide Mario through to the Boost Star.

The Crystal Planet is mainly just a treat, more like a bonus planet.

Rock Planet
The Rock Planet is a planet in Super Mario Galaxy. It is mostly made of maroon, dark red, brownish rock. It has a sort of arch, as seen in the picture, that looks like an entrance to the Tarantox's lair, and it practically is. The pre-boss music begins when Mario lands on this planet, and the spider's Sticky Planet is nearby.

The Rock Planet is the first planet in the game to have a Wobble Launcher and is the beginning of a long path of Wobble Launchers.

Space Ship
The Space Ship is a place in Super Mario Galaxy. It consists mostly of just coins. It is a big, long, red-and-tan space ship floating around in space. It is encountered on the route to Tarantox. At the end of it is a Wobble Launcher, at that's literally all there is, along with a few Cosmic Scuttle Bugs. The ship resembles Captain Olimar and Louie's Ship in Pikmin 2.

Sticky Planet
The Sticky Planet is a big white planet in Super Mario Galaxy that looks like a mega version of the top of a Sling Pod. In fact, Mario uses a Sling Pod to get to the planet, breaking its shell open and revealing a giant sticky spider web, where he fights Tarantox, who is frozen inside the Sticky Planet.

Yoshi Planet
The Yoshi Planet is a planet in the shape of a large, wooden Yoshihead that shoots red steam out of its nose. It is located in the Space Junk Galaxy. This appears to be the second reference to the Yoshi clan in Super Mario Galaxy, the first being the Yoshi Egg Planet that was shown earlier.
