The name was selected in the NameExoWorlds campaign by Sri Lanka, during the 100th anniversary of the IAU.
In the case of HD 205739, the star was observed using the Magellan Telescopes at Las Campanas Observatory in Chile.
[3] HD 205739 was flagged originally as a candidate hosting a Hot Jupiter, which is a large gas giant that orbits closely to its star, although later observations suggested that the planetary candidate orbited further out over the next 3.5 years of observation.
[3] The star was studied through the Magellan Inamori Kyocera Echelle spectrograph's (MIKE) ability to use Doppler spectroscopy to measure radial velocity.
With an effective temperature of 6176 K, HD 205739 is also hotter than the Sun, although it is younger, at an estimated age of 2.84 billion years.
