Planet X was first discovered in 1983 by infrared telescopes and appeared to be on an inbound trajectory. Since then, the United States has built numerous underground facilities (such as at Cheyenne Mountain), which will be offered as a survival option to only an elite few. China has reportedly also completed the construction of underground facilities.
The rogue planet will first be visible as a new star– it’s been calculated to be five times the size of Earth, and has several attached moons– adding that the timing could be one year later. Solar flares connected with Nibiru’s passage could wipe out all electronic devices, and a multitude of large meteorites hitting the oceans will cause immeasurable tsunami.
