Comet Medals are a type of item that appears in Super Mario Galaxy 2. They are white octagonal coins with a golden lining and a picture of a golden comet imprinted on them. Collecting enough Comet Medals makes Prankster Comets appear, like the Prankster Comets in the first game. They are found in the first mission of every galaxy, usually in hard to reach places or requiring the use of a power-up. Once collected, if the player re-enters the level, the Medal appears to be a clear blue silhouette of the original. It can still be collected, and by doing so, it is temporarily added to the total until exiting the level by any means.

There are 49 Comet Medals total, but not every galaxy has a Prankster Comet, even after every Comet Medal has been collected. The counter can temporarily increase up to 50 if a previously-collected Comet Medal is picked up again on a repeat visit to the stage after collecting all the other medals.

Comet Medals also appear in Puzzle & Dragons: Super Mario Bros. Edition. They raise the Skill levels of both forms of Rosalina and all types/forms of Cheep Cheeps and Bloopers from levels 1-4, while Grand Comet Medals raise from levels 5-7.

Trivia

 * When collected, the Comet Medal makes a similar sound effect to that of a Red Coin from Super Mario Sunshine, but on a different instrument.
 * On the official Nintendo game overview page, Comet Medals are misspelled "Comet Metals."
 * The Star Medals in Super Mario 3D Land feature a design similar to that of Comet Medals.
