The '''Gateway Galaxy''' 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. The galaxy is one of two galaxies (the other one being the [[Buoy Base Galaxy]]) to only feature two [[Power Star]]s. It is unrevisitable until the [[Gate (Super Mario Galaxy)|Gate]] is unlocked later on in the game. 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=====
{{conjecture|section=yes}}
[[File:Gatewayplanet.png|200px|thumb|left|The Starting Planet]]
This is the first planet 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 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 flowers, 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.

[[Deep Dark Galaxy#Gateway Galaxy Planet|A planet]] found in the [[Deep Dark Galaxy]] resembles the Starting Planet of the Gateway Galaxy. It can be seen from the [[Deep Dark Galaxy#Wooden Planet|Wooden Planet]], as well as the [[Deep Dark Galaxy#Starting Planet|Starting Planet]]. The planet is accessible via a [[cannon]] on the latter, and is much smaller than the original one. There are three [[Goomba]]s here, and a yellow screw 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.

=====[[Black hole|Black Hole]] Planet=====
{{dev data|section=yes}}
[[File:Black Hole Planet.png|200px|thumb|left|[[Mario]] collecting [[Star Chip]]s on the {{conjectural|Black Hole Planet|planet}}.]]
The Black Hole Planet<ref>Name confirmed by files found on noclip. [https://noclip.website/#smg/HeavensDoorGalaxy].</ref> is a planet made of nothing more than dirt, grass and stone. There is a [[black hole]] at its center, and it is also under constant bombardment by a [[meteor]] shower. There are five yellow [[Star Chip]]s on this planet that Mario must collect in order to proceed, as well as a rock with a [[1-Up Mushroom]] on top of it.

=====Metal planets=====
[[File:SMG Grand Goomba.png|thumb|left|200px|Mario on the planet]]
[[File:Metal Planets.png|200px|thumb|The two metal planets in the Gateway Galaxy.]]
These are two metal planets which look very similar to one another. Both planets 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 them, 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. Also, on the second of the two is a [[Big Goomba|Grand Goomba]], the only one in the entire game. The Flipswitch Area is located inside the second metal planet, and is accessed via a [[Warp Pipe]].
{{br}}

=====Flipswitch Area=====
{{conjecture|section=yes}}
[[File:Flipswitch Area.png|200px|thumb|left|The {{conjectural|Flipswitch Area|area}}, located inside the second of the two Metal Planets.]] 
[[File:SMG Gateway Metal Planet Interior.png|200px|thumb|The draining device]]
When the player enters the Warp Pipe on the bottom of the second Metal 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 activating 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.

==Trivia==
*This is the only galaxy in the game where [[Flipswitch Panel]]s have circles in the middle instead of a "?" or "!" and must be turned off rather than on.
*This is the only galaxy in the game where the normal music does not play when chasing the bunnies. Instead, the music from this galaxy is remixed.
*In the background (like Bowser's Star Reactor later on in the game), there are inaccessible Airships. They are revealed by using a flight hack that the Airships are solid, but have no gravity. However, the camera is very glitchy when Mario or Luigi stands on them.<ref>https://tcrf.net/Super_Mario_Galaxy/Unused_Zones</ref>
