HAT-P-9 is a magnitude 12 F star approximately 1500 light years away in the constellation Auriga.[2] A search for a binary companion star using adaptive optics at the MMT Observatory was negative.[5]
The star HAT-P-9 is named Tevel. The name was selected in the NameExoWorlds campaign by Israel, during the 100th anniversary of the IAU. The Hebrew word תֵבֵל tevel means "World" or "Universe".[6][7]
Planetary system
An exoplanet orbiting the star, HAT-P-9b, was discovered by the transit method on June 26, 2008.[3]
