TrES-3b is an extrasolar planet orbiting the star GSC 03089-00929. It has an orbital period of just 31 hours and nearly twice the mass of Jupiter.

The planet TrES-3b is named Umbäässa. The name was selected in the NameExoWorlds campaign by Liechtenstein, during the 100th anniversary of the IAU. In the local dialect of southern Liechtenstein, Umbäässa is a small and barely visible ant.[2][3]
