Red Power Star

From the Super Mario Wiki

The Red Power Star is a red-colored Power Star that is found in Super Mario Galaxy.

There is only one Red Power Star, and it can be located in the Gateway Galaxy after Mario passes through the Gate in the Comet Observatory. There Mario will find Princess Rosalina, as well as a Red Luma, who will allow him to use Red Stars to become Flying Mario, so that he is able to collect one-hundred Purple Coins. Upon doing so, the Red Power Star will appear for Mario to collect.

After collecting the Red Power Star, Mario will have access to Red Stars in the Comet Observatory, and will be able to fly around the place at his leisure. Other than that, the Red Power Star has no other special attributes.
