The Moon is a celestial body, the only natural satellite of Earth. During the events of Katamari Damacy, The King of All Cosmos accidentally destroyed it while out on a bender. It is the last object that The Prince needs to collect items for. After a new Moon is created, it is used as a special Katamari in the Credits bonus game.
In We ♥ Katamari, The Moon can be seen orbiting the Earth in the Cosmos during the Roll up the Sun stage. It is quite easy to roll up as the first item on the katamari. If the save data from Katamari Damacy is transferred to your save file, the Moon will be slightly bigger and glow brighter depending on how big the katamari from the first game was. It is later used to once again collect the countries in the Save the Earth! stage from a falling asteroid, this time creating a new planet for the Cosmos. It does not look any different if save data is transferred.
In Me & My Katamari, the Moon can be seen in the Gorilla stage when the rocket launches into space.
In Beautiful Katamari, The Moon is created in the first stage of the game, Egg School. After the Moon is made, up to 9 extra moonlettes can be made that will orbit the Moon in the Cosmos.

In Katamari Forever, Katamari Damacy's Make The Moon stage reappears in this game. The minimum size of the katamari is 300m, while the largest possible (seen so far) size is 904m 93cm 7mm The credits game, however, does not.
Appearance

In Katamari Damacy, the Moon is a yellow ball and is covered in darker spots that are supposed to resemble craters, In We ♥ Katamari and onwards, the Moon is shown to have visible craters that protrude from its surface and has a yellow glow around it, the Moon's satellites in Beautiful Katamari are shown to be the falling rock items from the game. The Moon can be created four times in Katamari Forever.
The Moon as a Katamari
In the games, there has been only two real instances where The Moon has been used as a katamari, it has first been used in the Katamari Damacy/Katamari Damacy REROLL end mini game where The Prince rolls around The Moon to roll up all the countries on the planet.
In We ♥ Katamari, this same concept is used again in this game to roll up all the countries, but instead of it being a fun mini game, it's a mission to stop a meteor from crashing into the planet.
The moon's appearance changes in these two games, in the first game, the moon being rolled looks completely smoothed out with a few dark spots meant to represent craters. In the second game, the moon looks more like how it does in the games after Katamari Damacy, it shows craters that pertrude from the surface and it is not completely round.
