The discovery of a new beyond-the-Kuiper-Belt object is quite a good one. We see objects because they reflect sunlight, since only the Sun is actually luminous. So when we have really small objects way out where there isn't much sunlight, then it's quite an accomplishment to find and track them. After all, it was ten years between Sedna and VP113.
In 2014 Sheppard and Trujillo also published papers on two new Kuiper Belt objects - also possible dwarf planets - and they are observing several more possibles.
My objection to the story was that there were far too many conclusions for the amount of evidence available. But maybe one day, they will have the Big Story.
