In 2006, Pluto was reclassified as a “dwarf planet.” This had two main effects on our solar system: it reduced the number of recognized planets to eight, and left many Earthlings very sad. But Pluto’s demotion reignited a conversation that scientists have had since Neptune’s discovery: is there a “Planet X” orbiting the Sun that we don’t yet know about?

It has to be Minerva. We have Venus and Gaia (Earth) represented, yet male gods dominate the names of the solar system’s planets.
As for the Nibiru fans, ancient doomsday prophecies lost their appeal after 2012 ~ sorry.

Planet IX makes a little more sense, since Neptune is planet VIII. Like Catnip used to say; “That sounds logical…”

Imagine that, the Mayans were right. 900 years ago they documented 10 planets in our solar system.

If you like this video check out the channel ParallaxNick. He’s got four videos on PlanetX and many other great ones too. I think I’ve watched almost every video he’s made so far within the last couple months that I’ve known about him.

But then there would have been no point in demoting Pluto from planet status. See, planet X got its name by being planet number 10. With Pluto no longer being planet number 9, that leaves the slot for number 9 open! Thus removing the ability of saying “conspiracy confirmed” by all those who have been saying planet X is out there and the govt has been watching and hiding it for decades. They’ve known about it since the late 50s and they know theres nothing to be done about it except hopefully survive the effects. Pole shift, catastrophic climactic changes, etc. The whole, man-made climate change thing is an attempt to cover up the effects of planet X approaching.

Ancient Sumerian tablets say Pluto was a moon of Neptune ripped away by nibiru during a fly by.

Our government has been hiding planets from us for a long time. They know what is coming and they have been digging their tunnels for years. Take Jesus as you Lord and Savior before it’s to late.
“Then the kings of the earth, the princes, the generals, the rich, the mighty, and everyone else, both slave and free, hid in caves and among the rocks of the mountains. They called to the mountains and the rocks, “Fall on us and hide us from the face of him who sits on the throne and from the wrath of the Lamb! For the great day of their wrath has come, and who can withstand it?””
