(Dwarf) Planet Pluto

One of the objects of this work is humor, but it offers solid scientific facts. Pluto once was one of the nine planets of our solar system, but the IAU demoted it to the status of dwarf planet. One of these articles personifies Pluto and shows his reaction to his rise and fall. Another article offers a more scientific treatment of Pluto and its satellites. A third article concerns itself with Eris. The fourth article offers more results of the New Horizons mission and treats Arrokoth.
