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, however. It is temporarily added to the total, but as soon as the level is completed, the total reverts back to its previous value.

There are 49 Comet Medals total, but not every galaxy has a Prankster Comet, even after every Comet Medal has been collected.

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.
 * If the player collects an already collected Comet Medal and pauses the game, it counts it to the collection. However, when players return to the hub world, the count gets reverted. It is also worth noting that the number of collected Comet Medals can temporarily be 50 if the player picks one after collecting all 49 Comet Medals.
