It's looking likelier that there is an undiscovered planet orbiting beyond the Kuiper belt. If it's there, it's roughly 10 times the mass of Earth (or about half the mass of Neptune), likely never gets closer to the Sun than about 100 AU, and takes more than 10,000 years to orbit the Sun.

Late last year, a small team from Honeybee Robotics went to a gypsum quarry to test Planetary Deep Drill, a technology prototype designed to chew tens—and eventually, hundreds—of meters beneath icy planetary surfaces.
