HD 63454 b (also known as Ibirapitá) 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 , Mayor, and using the radial velocity method.

- HD 63454 b는 카멜레온자리 방향으로 지구로부터 약 117광년 떨어진 곳에 있는 외계 행성이다. 어머니 항성 HD 63454는 태양보다 훨씬 더 어두운 K4형의 주계열성이다. b의 질량은 최소 목성의 38퍼센트 수준이며, ‘지글지글 끓는’ 간격만큼 항성에 붙어 있는데, 그 거리는 페가수스자리 51 b보다 가깝다. (ko)
- HD 63454 b (Ibirapitá) – planeta typu gorący jowisz orbitująca wokół gwiazdy HD 63454. Jest około trzy razy mniej masywna niż Jowisz. Została odkryta w 2005 roku. (pl)
- HD 63454 b (también conocido como Ibirapitá) es un planeta extrasolar ubicado aproximadamente a 117 años luz de distancia en la constelación de Chamaeleon, orbitando la estrella HD 63454. Tiene al menos un 38% de la masa de Júpiter y orbita muy cerca de su estrella anfitriona, incluso más cerca que el famoso 51 Pegasi b. Su órbita cercana significa que pertenece a una clase de exoplanetas conocidos como Jupíteres calientes. Este planeta tiene una de las órbitas menos excéntricas. Fue descubierto el 14 de febrero de 2005 en el observatorio de La Silla, en Chile. (es)

HD 63454 b, now known as "Ibirapitá", was discovered in 2005 by , Mayor, and using the radial velocity method. 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.
