Naming
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 winning name was Sancho for this planet.[5] The winning name was submitted by the Planetario de Pamplona, Spain. Sancho was the squire of the lead character of the novel Don Quixote.[6]
