GSC 03089-00929 is a magnitude 12 star located approximately 760 light-years away in the constellation of Hercules. This star is a G type main sequence star that is similar to but slightly cooler than our sun.[2] This star is identified in SIMBAD as a variable star per the 1SWASP survey.[6]
The star GSC 03089-00929 is named Pipoltr. The name was selected in the NameExoWorlds campaign by Liechtenstein, during the 100th anniversary of the IAU. In the local dialect of Triesenberg, Pipoltr is a bright and visible butterfly.[7][8]
Planetary system
In 2007 the TrES program found exoplanet TrES-3b orbiting this star by using the transit method.[9]
The transit timing variation analysis did not reveal any additional planets in the system as of 2020.[10]
