In 2015, in partnership with NASA’s New Horizons mission and the SETI Institute, the International Astronomical Union (IAU) endorsed the Our Pluto naming campaign, which allowed the public to participate in the exploration of Pluto by proposing names for surface features on Pluto and its satellites that were still awaiting discovery. Each of the system’s six worlds was designated a set of naming themes set out by the IAU’s Working Group for Planetary System Nomenclature (WGPSN – https://www.iau.org/science/scientific_bodies/working_groups/98/ ). The public responded with overwhelming enthusiasm, suggesting and voting on thousands of names within these categories, as well as proposing names not fitting the approved set of themes.
