The 170-Year Search for a Planet Beyond Neptune I NOVA I PBS
Planet Nine’s existence is not the first time astronomers have predicted a planet they couldn’t see. Clyde Tombaugh was looking for Planet X when he accidentally found Pluto. After Voyager 2 flew by Neptune in 1989, new calculations determined there was no Planet X. But three years ago, a disturbance was detected at the far reaches of the Solar System.

Nibiru and four other planets sit in our night skies and has been since at least 2012. Truth.. witnessed its rise.

Jesus messages (through a new mexico grandma, a catholic visionary. She is one of many catholics seers who see and receive God messages for the world, study God's messages before too late.) to us people living at this endtime.
Summary, God's Book of Revelation prophesies must be fulfilled first of all
there are bad scientists…. hiding and misusing God-given resources for war for ill-technologies to create, mutate, control humanities for their blind ambitions in such ways that they don't even see what is not right for themselves or their children…
All these and such and alike need to be cleansed.
God says otherwise when the truly innocents grows up, all they will do is go directly to Hell with satan's help in this world.
At least this way, the innocents and babies will be with God in Heaven.

The solar system already has a ninth planet. It's called Pluto. I don't care what the astronomers say. Their definition of a planet is baseless and arbitrary.

Nice cover story NASA. The sloppiness of these people is amazing. They (the controllers in charge, they think, of us) actually believe we are stupid because of all the shot they do to us to try to dumb us down. I’m not any dumber, are you? They are the ones getting dumber. Did you see the image of what appeared to be s UN meeting? They needed that many people to downgrade Pluto? Actually they did because every nation needs to cover this lie. SO, THERES NO PLANET X. Instead there’s s planet IX.
I love Roman numerals. It says planet I X. Get it I Am X. IX is the number 9. I’m laughing so hard my gut hurts. Stupid stupid 1% ers!

They didn't even try to describe the new "disturbance", they just dropped the ball right before the end zone. I've noticed this is an irritating new pattern with these videos.

They don't think Planet X was anything out there. They think it is a tenth planet in our solar system that is somehow on a collision course with earth. Which is obviously not true In fact Planet X has allegedly been called Nibiru and has links to Sumarian mythology.
