What is the name of the satellites and robot that have been to Pluto?

The primary spacecraft that has visited Pluto is NASA's New Horizons, which conducted a flyby in July 2015. While there are no robotic landers on Pluto, New Horizons carried scientific instruments to gather data about the dwarf planet and its moons during its brief encounter. The mission significantly enhanced our understanding of Pluto's geology, atmosphere, and composition.
