In early 2016, two planetary scientists declared that a ghost planet is hiding in the depths of the solar system, well beyond the orbit of Pluto. Their claim, which they made based on the curious orbits of distant icy worlds, quickly sparked a race to find this so-called Planet Nine—a planet that is estimated to be about 10 times the mass of Earth.

Now, astronomers are reporting that they have spotted another distant world—perhaps as large as a dwarf planet—whose orbit is so odd that it is likely to have been shepherded by Planet Nine. The object confirms a specific prediction made by Konstantin Batygin and Michael Brown, the astronomers at the California Institute of Technology who first argued for Planet Nine’s existence.

Its orbit is tilted 54 degrees with respect to the plane of the solar system. It’s something Gerdes did not expect to see. Batygin and Brown, however, predicted it.
Maybe there will be a Planet X discovered after all?

At this point, it will be the ninth planet, though I do admit that Planet X has a nice ring to it.

Notwithstanding the hype, hysteria, disinformation and misinformation surrounding Planet X, my understanding is that the celestial body has an orbital period of 3,600 years; travels in a clock-wise motion like nearly all comets, instead of a counter-clockwise motion like all of the planets; with a mass that is two to five times greater than Earth; comes out of the south, such as from the direction of the Constellation Hydra, which would mean its orbit is inclined to the Plane of the Ecliptic by as much as 30°; and was last present circa 1390 BCE, which would make its exact return about 2210 CE, but detectable as early as 2140 CE, assuming technology for detection is continually enhanced.
