Launch Star

A Star Ring is an item in Super Mario Galaxy. It looks a bit like a rotating Sherrif's Star in mid-air, and when Mario walks up to it, then spins, (using the Wii Remote,) he can boost at an ultimate speed from planet-to-planet using their powers that literally throw him off a world. They are first seen in the Star World, the first (known) level in Super Mario Galaxy.

Star Rings often let Mario fly through space before landing on another planet, unlike their smaller sister items, Spring Stars, which are also found around the game. During the flights through space, Mario can grab floating Star Shards by using the Star Cursor to grab them.
