Editing Gateway Galaxy

|stars={{icon|SMG-StarGrand}}{{icon|SMG-StarRed}}

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.

=====Metal planets=====

[[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]].

|name1=Mario's First Journey

|description1=''On his first stop in the galaxy, Mario learns how to navigate the gravity field and avoid the life-threatening black hole, which is in the center of this little planet. Mario can also use his newfound ability to Star Spin to shatter crystals that have encased Star Chips. Once Mario collects all five, he can assemble the Launch Star and rocket to the next galaxy.''

|description2=''This metal planet is plagued by Goombas, so Mario needs a quick way to get rid of these baddies. Star-Spin next to the planet's tall spire and send a shock wave that stuns all the enemies. Grab the key from the Luma, and launch to the next metal planet, where an even bigger Goomba awaits. Here, Mario must free a Grand Star and launch to the Comet Observatory where the real challenges begin.''

|description3=''After Bowser's attack and blast that sent Mario drifting out into space, our hero wakes up on this planet. He's greeted by a Luma that wants to teach him important planet-hopping tricks. This is where he meets Rosalina, who grants him a critical power — the Star Spin. Mario will stop here again toward the end of his journey to acquire the power of flight from a Red Luma.''

*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>
