As the name suggests they are star-like in appearance with the default 5 points. The faster a Starite is obtained the more Ollars Maxwell can get at the end of a level.
The Starite can be manipulated so it can be easy or hard to get. For example; if a Starite is capable of rolling it an be attached to items such as rope or a net. Also Starites can be blown up, pushed down holes and burnt also. In some of the 'Action' stages Maxwell can be seen trying to avoid dropping a Starite incase it may break. It's also under threat of spiked balls and other heavy/rolling objects that may also cause it to break.
If you type in "Starite" into the notepad a real one will not appear, only a "Dud" one, it can however, be used as a ball and can be thrown at other objects or characters. But in Level Editor, there is a choice to spawn a real Starite as the goal for the end of the level. You can create "dud" ones by typing in words such as "ftw" and "the answer".
