HAT-P-3b, also named Teberda, is an extrasolar planet that orbits the star HAT-P-3 approximately 450 light-years away in the constellation of Ursa Major. It was discovered by the HATNet Project via the transit method and confirmed with Doppler spectroscopy, so both its mass and radius are known quite precisely. Based on these figures it is predicted that the planet has about 75 Earth masses' worth of heavy elements in its core, making it similar to the planet HD 149026 b.[3]

The planet HAT-P-3b is named Teberda. The name was selected in the NameExoWorlds campaign by Russia, during the 100th anniversary of the IAU. Teberda is a mountain river in Dombay region (name of HAT-P-3).[4][5]

In 2013, this planet was photometrically observed by Spitzer Space Telescope which characterized its near-zero eccentricity and low albedo.[6]
