LTT 9779 (or Uúba) is a G-type main-sequence star located 264 light-years (81 parsecs) away from the Solar System in the constellation of Sculptor.
The designation LTT 9779 comes from one of Luyten's catalogues of stars with high proper motion.
[5] The approved names, proposed by a team from Colombia, were announced in June 2023.
[3] Observations using the Spitzer Space Telescope have measured the planet's dayside temperature at 2,305 K (2,032 °C; 3,689 °F),[7][8] and observations by CHEOPS have shown the planet to be highly reflective, with an albedo of 80%.
[9][10] A study published in 2019, prior to the confirmation of LTT 9779 b, proposed a second candidate planet in the system based on transit timing variations, but this has not been confirmed,[11] and the study that confirmed LTT 9779 b found no evidence of transit timing variations.
