The planet HD 118203 b is named Staburags. The name was selected in the NameExoWorlds campaign by Latvia, during the 100th anniversary of the IAU. Staburags is the name of a character from the Latvian poem Staburags un Liesma, and denotes a rock with symbolic meaning in literature and history.[3][4]
In 2019 the transits of the planet were detected with the Transiting Exoplanet Survey Satellite. The host star is one of the brightest stars for transiting planets and HD 118203 b is therefore a good target for follow-up observations.[2]
