The '''Gateway Galaxy''', the '''gateway to the starry sky''', is the first of the many [[galaxy|galaxies]] from ''[[Super Mario Galaxy]]'' for the [[Wii]]. It serves as the opening level for the game and after [[Mario]] clears its first mission, it is unrevisitable until the [[Gate (Super Mario Galaxy)|Gate]] is unlocked later on in the game. The galaxy is one of two galaxies (the other one being the [[Buoy Base Galaxy]]) to only feature two [[Power Star]]s. It has the only [[Purple Coin]] mission in the game that can be played before beating [[Bowser]]. This galaxy is one of the two galaxies to have a purple coin mission without a [[Prankster Comet]], the other one being the [[Grand Finale Galaxy]]. The Gateway Galaxy also contains the only [[Grand Star]] not obtained by fighting a [[List of bosses|boss]], as well as the only [[red Power Star]] in the game.

===Starting planet===
[[File:Gatewayplanet.png|200px|thumb|left|The starting planet]]
The starting planet is the first one that Mario explores in the game. It is where Mario first wakes up after being blasted off [[Peach's Castle]] by [[Kamek]] in the opening cutscene. Here, he meets two yellow [[Luma]]s as well as an [[Baby Luma|Apricot Luma]] who transform into [[Star Bunny|Star Bunnies]] and asks him to play hide and seek with them. When they are all found, a large light beam goes down from the sky, and the gateway appears, and it is where Mario meets [[Rosalina]] for the first time. The planet itself has three holes in its surface (two of which connect to each other directly through the center of the planet), many small patches of [[flower (environmental object)|flower]]s, two connecting [[Warp Pipe]]s, several [[rubbery bulb]]s, two small pools of water, two small cottages, a ring of vertically-positioned rock columns, and a castle-like monument on the top. The planet is also surrounded by a light blue atmosphere. Later in the game, Mario must use the power of the [[Red Star]] to collect 100 Purple Coins on this planet, enabling him to use the Red Star onboard the [[Comet Observatory]] as well. Rosalina mentions that this planet is dear to her and she looks forward to visiting it with the Lumas every one hundred years.

A planet found in the [[Deep Dark Galaxy]] resembles the starting planet of the Gateway Galaxy. It can be seen from the wooden planet, as well as its starting planet. The lookalike is accessible via a [[cannon]] on the latter, and is much smaller than the original planet. There are three [[Goomba]]s here, and a [[Screwtop|golden bolt]] that can be unscrewed by [[Spin|spinning]] it, which will cause the planet to quickly shrink and disappear, at the same time revealing a large ring of [[coin]]s.

After the credits have rolled, when the player has collected 120 [[Power Star]]s and defeated [[Bowser]] for a second time, the ending sequence that plays occurs here. In the sequence, Rosalina thanks the player and says that she will watch over them from beyond the stars. She then walks into the door of the small blue-roofed cottage on the planet and comes out of the door of the Gate, thereby revealing that the two are connected. It is also revealed that the Comet Observatory is most likely hidden somewhere on the planet (although it cannot be seen when the player actively explores it), as it emerges from behind the planet after Rosalina transforms it into a comet once again and pilots it away.

===Other planets===
[[File:Black Hole Planet.png|200px|thumb|left|[[Mario]] collecting [[Star Chip]]s on the hollow planet.]]
There are several other planets visited only during "[[Grand Star Rescue]]." They are inaccessible in subsequent visits to the Gateway Galaxy. The first of these is a another grassy planet, this one hollow and covered in holes. A [[black hole]] is at its center, and it is also being bombarded by [[meteor]]s. There are five [[Star Chip|Yellow Star Chip]]s on this planet that Mario must collect in order to proceed, as well as a stone pedestal with a [[1-Up Mushroom]] on top of it.

[[File:SMG Grand Goomba.png|thumb|200px|Mario on one of the metal planets.]]
The assembled Launch Star brings Mario to one of two '''metal planets'''. Both are brown in color, and have what appears to be metallic green power cables embedded in their surfaces which snake around the planets. In addition, both planets have [[Shock Wave Generator]]s that, when spun, will send vibrations across their surfaces, stunning all enemies within range. There are many [[Goomba]]s on both of these planets, as well as several [[Crystal (Super Mario Galaxy)|crystal]]s. A [[Big Goomba|Grand Goomba]] occurs on the second metal planet, the only one in the entire game.

When Mario enters the [[Warp Pipe]] on the bottom of the second metallic planet, he will be taken to an inverted, spherical metal chamber with many [[Goomba]]s and [[Flipswitch Panel]]s inside. The goal is to shut down the machine and save the first of seven [[Grand Star]]s in the game by deactivating every Flipswitch Panel found on the inside of the planet to change all of them from yellow to blue, while simultaneously avoiding the many Goombas and electric platforms. There are several coins floating in the air as well. This is the only location in the game where Flipswitch Panels have circles on them instead of question marks or exclamation marks. It is also the only location where they must be turned off rather than on.

[[Airship]]s fly in the background during "Grand Star Rescue," but they cannot be visited. It is revealed by using a flight hack that the airships are solid, but they have no [[gravity]]. The camera is very glitchy when Mario stands on them.<ref>https://tcrf.net/Super_Mario_Galaxy/Unused_Zones</ref>
