"Hercolubus, a planet so called by the sages of antiquity, is a gigantic world, 5 or 6 times bigger than Jupiter. In the past it put an end to the Atlantean civilisation and it is approaching Earth again.
The impending approach of this heavenly body to our solar system will happen soon, so that everybody will be able to see. It will bring about great upheaval in all corners of our planet."

"Hercolubus is a RED ‘comet planet’ which presents an elliptical orbit of a comet and great mass of a planet, in other words “a planet with a tail”.
The star is charged with cosmic energy, as to say rarefied radiation which according to scholars alter the behavior and health, and will provoke incurable epidemics and irritability, bringing wars.
Does not meet the conventionally established celestial physical laws"

"When Hercolubus comes closer to the Earth and aligns with the Sun, deadly epidemics will begin to spread over the entire planet. Neither doctors nor official science will know what sort of illnesses they are or how to cure them. They will be powerless in the face of the epidemics."
