HD 108147 b, also named Tumearandu, is a
gas giant exoplanet
An exoplanet or extrasolar planet is a planet outside the Solar System. The first possible evidence of an exoplanet was noted in 1917 but was not recognized as such. The first confirmation of detection occurred in 1992. A different planet, init ...
with a
minimum mass about half that of
Jupiter. It orbits the star in a very tight "torch orbit". The distance between the planet and the star is only a tenth of the distance between
Earth and the Sun (0.1AU).
A number of such worlds are known to exist, but the
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.
