HD 1502 (proper name Citadelle) is an 8th-magnitude K-type star in the constellation of Pisces, located at a distance of approximately 630 light-years.
Description
The star has evolved past the main sequence stage and is now a subgiant with a mass of 1.6 M☉, a radius of 4.0 R☉, and a spectral type of K0.[1][2]
In 2011, an exoplanet orbiting HD 1502, designated HD 1502 b, was discovered using the radial-velocity method.[1] HD 1502 b revolves around its host star with an orbital period of little over one year, and has a minimum mass of 2.75 MJ.[2] It's radius is predicted to be 1.183 times that of Jupiter.[2]

Naming
In 2019, the Republic of Haiti was assigned to giving the HD 1502 system a proper name as part of the IAU100 NameExoWorlds Project, planned to celebrate the hundredth anniversary of the International Astronomical Union (IAU), which grants the right to name an exoplanetary system to every state and territory in the world.[3] Names were submitted and selected within Haiti, which were then presented to the IAU to be officially recognized.[4] On 17 December 2019, the IAU announced that HD 1502 and its planet, b, were named Citadelle and Indépendance, respectively.[5] Citadelle refers to the Citadelle Laferrière, a fortress located in Milot in northern Haiti, which was built in 1820 and declared a world heritage cite in 1982 as part of the National History Park. Indépendance was named after the declaration of independence of Haiti, in celebration of the country's independence on 1 January 1804[5]。
