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 in 2020.[10]
