Xi Aquilae b (abbreviated ξ Aquilae b, ξ Aql b), formally named Fortitudo {{IPAc-en|f|ɔr|t|ɪ|ˈ|tj|uː|d|oʊ}}, is an extrasolar planet approximately 184 light-years from the Sun in the constellation of Aquila. The planet was discovered orbiting the yellow giant star Xi Aquilae in 2008. The planet has a minimum mass of 2.8 Jupiter and a period of 137 days.

Name

Following its discovery the planet was designated Xi Aquilae b. In July 2014 the International Astronomical Union launched NameExoWorlds, a process for giving proper names to certain exoplanets and their host stars.[http://www.iau.org/news/pressreleases/detail/iau1404/ NameExoWorlds: An IAU Worldwide Contest to Name Exoplanets and their Host Stars]. IAU.org. 9 July 2014 The process involved public nomination and voting for the new names.{{Cite web |url=http://nameexoworlds.iau.org/process |title=NameExoWorlds The Process |access-date=2015-09-05 |archive-date=2015-08-15 |archive-url=https://web.archive.org/web/20150815025117/http://www.nameexoworlds.iau.org/process |url-status=dead }} In December 2015, the IAU announced the winning name was Fortitudo for this planet.[http://www.iau.org/news/pressreleases/detail/iau1514/ Final Results of NameExoWorlds Public Vote Released], International Astronomical Union, 15 December 2015.

The winning name was submitted by Libertyer, a student club at Hosei University of Tokyo, Japan. Fortitudo is Latin for 'fortitude'. Aquila is Latin for 'eagle', a symbol of fortitude – emotional and mental strength in the face of adversity.{{Cite web |url=http://nameexoworlds.iau.org/names |title=NameExoWorlds The Approved Names |access-date=2016-01-05 |archive-date=2018-02-01 |archive-url=https://web.archive.org/web/20180201043609/http://nameexoworlds.iau.org/names |url-status=dead }}
