The 993-day period planet orbits the yellow giant star 18 Delphini. A very massive and dense planet with a minimum mass of Template:Jupiter mass, it was discovered on February 19, 2008, by Bun'ei Sato.[2]
In July 2014, the International Astronomical Union launched NameExoWorlds, a process for giving proper names to certain exoplanets and their host stars.[3] The process involved public nomination and voting for the new names.[4] In December 2015, the IAU announced the name Arion for this planet.[5] The winning name was submitted by the Tokushima Prefectural Jonan High School Science Club of Japan. Arion was a genius of poetry and music in ancient Greece. According to legend, his life was saved at sea by dolphins after attracting their attention by the playing of his kithara[6] ('Delphinus' is Latin for 'dolphin').
