Silver stars are special stars within the Super Mario Galaxy series. When Mario collects a silver star it will follow him. When Mario collects all five, a regular gold star will be released. This star will be placed in a set location and not just given to Mario. They are only found in certain missions. If Mario dies, the Silver Star count goes back to zero.
- Silver stars share a trait with star chips. Both need five of them to get a bigger, more useful object.
