HD 30562 is a 6th magnitude F-type main sequence star located approximately 85 light years away in the constellation of Eridanus. In August 2009, it was found that this star has a Jupiter-like planet that orbits in a very eccentric path.[3][4]
The star HD 30562 is named Mouhoun. The name was selected in the NameExoWorlds campaign by Burkina Faso, during the 100th anniversary of the IAU. Mouhoun, also called Volta Noire, is the largest river in Burkina Faso.[5][6]
