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 El Ingenioso Hidalgo Don Quixote de la Mancha.[6]
The planet's discovery was announced on June 13, 2002. Mu Arae e is a gas giant at least 1.8 times as massive as Jupiter. The planet orbits at Jupiter-like distance at 5.235 AU.
