Xi Aquilae b

Extrasolar planet in the constellation Aquila

Xi Aquilae b (abbreviated ξ Aquilae b, ξ Aql b), formally named Fortitudo /fɔːrtɪˈtjuːdoʊ/, 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.^[1]

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.^[2] The process involved public nomination and voting for the new names.^[3] In December 2015, the IAU announced the winning name was Fortitudo for this planet.^[4]

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.^[5]
