context_page_description: HD 63454 b is an extrasolar planet located approximately 117 light-years away in the constellation of Chamaeleon, orbiting the star HD 63454. It is at least 38% as massive as Jupiter, and orbits very close to its host star, even closer than the famous 51 Pegasi b. Its close orbit means it belongs to a class of exoplanets known as hot Jupiters. This planet has one of the least eccentric orbits. HD 63454 b, now known as "Ibirapitá", was discovered in 2005 by Moutou, Mayor, and Bouchy using the radial velocity method.
  After the 2019 IAU100 NameExoWorlds campaign, the International Astronomical Union, approved the names proposed from Uruguay: Ceibo for the star and Ibirapitá for the exoplanet. They are "Culturally significant species of trees native to Uruguay." Ceibo is the name of the native tree of Uruguay that gives rise to the national flower." And Ibirapitá is the name of a native tree that is characteristic of the country of Uruguay, and is also known as Artigas' tree, after the national hero.
  These names were announced on 17 December 2019, at a press conference of the IAU in Paris, together with other 111 sets of exoplanets and host stars.

  After the 2019 IAU100 NameExoWorlds campaign, the International Astronomical Union, approved the names proposed from Uruguay: Ceibo (Erythrina crista-galli) for the star and Ibirapitá (Peltophorum dubium) for the exoplanet. They are "Culturally significant species of trees native to Uruguay." Ceibo is the name of the native tree of Uruguay that gives rise to the national flower." And Ibirapitá is the name of a native tree that is characteristic of the country of Uruguay, and is also known as Artigas' tree, after the national hero.
  These names were announced on 17 December 2019, at a press conference of the IAU in Paris, together with other 111 sets of exoplanets and host stars. Ceibo and Ibirapitá were proposed by Adrián Basedas, from the Astronomical Observatory of Liceo Nº9, Montevideo, Uruguay, who won the national contest "Nombra Tu Exoplaneta", organized in Uruguay, to name HD 63454 and HD 63454 b.
