The goal of the Eris Explorer is to travel to and fly-by the most distant and remote dwarf-planet in the Solar System, Eris and it moon Dysnomia. Along the way, Eris Explorer will use the gravity of Jupiter, Saturn, and Neptune to increase its velocity to Eris, while dropping balloon-suspended probes into each of their atmospheres. Eris Explorer will be by far the longest operational probe in history spending almost 38 years in cruise.
