The transit of Exoplanet TrES-3b by CMHASD member & trustee Dr. Mike Rushton using an eVscope for the ExoClock project.
TrES-3b is a gas giant exoplanet orbiting the star GSC 03089-00929 a G-type star and is 0.02282 AU from its star. It has an orbital period of just 31 hours and nearly twice the mass of Jupiter. It was found by the Trans-Atlantic Exoplanet Survey in 2007. It was discovered in the constellation Hercules about 10 degrees west of the star Vega.
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.
