Gravity

Gravity is a feature of the Super Mario Galaxy series. In reality, it always pulls, but in the series, it does not depend on an object's mass. It returns in Super Mario Odyssey.

Types Of Gravity
There are four types of gravity depending on their "pull".

Standard Gravity
Standard Gravity occurs when the player can go around the planet without falling off. It is the main type of gravity in Super Mario Galaxy and Super Mario Galaxy 2 and only appears in certain areas of Super Mario Odyssey. Planets are still considered to have standard gravity if you can go around to their other side without falling off, even if those planets have Black Holes inside them.

Galaxies That Lack Standard Gravity
Most Galaxies have Standard Gravity, but some do not. Note that even Bowser's reactors have Standard Gravity on their reactor planets.

Super Mario Galaxy
Note that the Bubble Breeze Galaxy and [[Grand Finale Galaxy do not count since they center on a planet that is the size of the Earth itself.

Downward Gravity
This is the gravity that mirrors the main games. It goes in one direction and returns in Super Mario Odyssey, usurping Standard Gravity as the main gravity type.

Outward Gravity
This type of gravity involves Mario being pulled to the outside of the planet. It is quite rare.

Toroidal Gravity
This type of gravity involves Mario falling around the planet. It only appears in Super Mario Galaxy 2.

Galaxies With Toroidal Gravity

 * Tall Trunk Galaxy (Log and Trunk Wheel)
 * Space Storm Galaxy (Rocket Ship)
 * Bowser's Galaxy Generator (Lava Cylinder)

Irregular Gravity
Sometimes, gravity changes in small areas throughout a larger area, such as on a planet. Gravity Walls hint towards the Gravity direction with their arrows. These arrows may vary in their colour depending on the direction.
