HD 108147 b, also named Tumearandu, is a
eccentricity of this planet is unusually high. Planets orbiting very close to their parent stars usually have round orbits because of the tidal forces
between the bodies.
In December 2019, the International Astronomical Union announced the exoplanet will bear the name Tumearandu, after the popular character Tumé Arandú of the folklore of Paraguay. The name was a result of a contest ran in Paraguay by the Centro Paraguayo de Informaciones Astronómicas, along with the IAU100 NameExoWorlds 2019 global contest.[3]
