Pluto and beyond: Voyaging into interstellar space
Pluto! Enigmatic, icy, and (at one time) one of the nine planets to grace the solar system we call home. Now labeled a “dwarf planet†after contentious debate in 2006, Pluto sadly wasn't even able to complete one orbit around the sun between its discovery and demotion. Unfortunately for Pluto, size matters in the planet
