[4] In July 2014 the International Astronomical Union launched NameExoWorlds, a process for giving proper names to certain exoplanets and their host stars.

[6] In December 2015, the IAU announced the winning name was Taphao Kaew,[7] submitted by the Thai Astronomical Society of Thailand.

Further measurements of the radial velocity revealed another periodicity in the data unaccounted for by the first planet.

Observations of the photosphere of 47 Ursae Majoris suggested that the periodicity could not be explained by stellar activity, making the planet interpretation more likely.

[8] Further measurements of 47 Ursae Majoris failed to detect the planet, calling its existence into question.
