Most of us are pretty familiar with the eight planets in our Solar System. But did you know that at one point, there may have been a ninth planet in the mix? The only problem is...that planet seems to have gone missing. » Recap on Planet 9 🤍youtu.be/Yo0Bz-8ZeR8 » Subscribe to Seeker! 🤍bit.ly/subscribeseeker (then hit the little 🔔 icon and select "all.") » Watch more Elements! 🤍bit.ly/ElementsPlaylist » Visit our shop at 🤍shop.seeker.com This 9th planet researchers recently proposed is in the ballpark of Mars or Earth in terms of mass. Big enough to be a planet. Pluto is almost 50 times less massive than Mars, which is why it was reclassified as a Dwarf Planet all the way back in 2006. But the prevailing idea for what has been dubbed Planet 9 is something else entirely. Scientists proposed Planet 9 to explain why many objects way out past Neptune, in what’s called the Kuiper Belt, had elliptical orbits that appeared to mostly cluster in one quadrant of the solar system. Computer models showed that a very distant 9th planet with a highly elliptical orbit of its own could explain this observed clustering, but in order to make that model work, Planet 9 would have to be on the scale of 10 Earth masses. This newly proposed 9th planet is something completely different. What the researchers from the University of British Columbia and University of Arizona proposed in their recent paper is that billions of years ago the outer solar system had at least one Mars-sized planet, possibly more. Why? Well to them it seemed like something was off. The outer solar system formed the massive rocky cores of the gas giants; Jupiter, Saturn, Uranus, and Neptune. And there are several dwarf planets like little Pluto and smaller. But there’s nothing in-between, and to them that seemed unlikely. They backed up their hunch with computer models. Thanks to past models, scientists believe the outer planets once had different orbits that shifted as the planets grew and tugged on each other. #space #science #planet9 #universe #solarsystem #seeker Read More: Another Planet 9? Earth's twin may be hiding in the outer Solar System 🤍🤍inverse.com/science/earth-missing-twin "The eight planets of our Solar System aren’t the only ones we’ve ever had — they’re merely the survivors. But that doesn’t mean the other planets were destroyed." Scientists find evidence the early solar system harbored a gap between its inner and outer regions 🤍🤍sciencedaily.com/releases/2021/10/211015184250.htm "A new analysis of ancient meteorites by scientists at MIT and elsewhere suggests that a mysterious gap existed within this disk around 4.567 billion years ago, near the location where the asteroid belt resides today." How Did the Solar System Form? 🤍astronomy.com/magazine/greatest-mysteries/2019/07/39-how-did-the-solar-system-form "While many ideas in astronomy have changed radically over time, the notion of how the solar system formed has changed little in the last 250 years. In 1755, German philosopher Immanuel Kant first proposed the nebular hypothesis, in which a great cloud of material, the solar nebula, preceded the Sun and planets."

I’m sticking with Pluto. It’s a planet. The scientists just wanted attention in 2006 and THEY need to get over it.

Yea it’s called Thea.. you know the planet that smashed into earth to create the moon. It was between earth and mars

My opinion:
They are constantly changing things...and IMO honestly, nothing should be set in stone until they're sure. At one point we had 10 planets. For like a whole 5 minutes 😂 and then they changed their minds and were like "ya nvm"😂 both of these orbits are just too far away and irregular and their mass just doesn't fit the planetary definition. And the one they had found was not dominating enough of it's own orbit space. It was Eris and Pluto. So then we went down to 8. 🤷🏻 And ya know ancient civilizations relied HEAVILY on our skies. And maybe "they" do research on it idk... But it seems like there is a lot more of trying to prove new theories and things then looking at what has already been thought to be discovered. It's quite obvious our ancient civilizations were quite smart and made use of what they had even if some things were a bit different. We got Hubble seeing distant galaxies but can't find the "supposed" 50 dwarf planets in our own Solar System 🤔🤷🏻

Surely if there is a 9th planet the James Web Telescope will find it!!

Come on every one knows that the asteroid belt between Mars and Jupiter is the remnants of the 9th missing planet that was destroyed by a moon sized space station.

Yeah, the 'WOKIES' Had to 'Cancel' Pluto, because its classification as a 'Dwarf' planet was declared 'Discriminatory' against "Little Planets"! NOBODY wants to admit, it happened at the same time as the beginning of the 'WOKE' and 'Cancelling', movements started !

Read Zachariah Stitchin, not a new theory, that’s why the asteroid belt exists

The missing planet was Nibiru destroyed by its own habitats through war which is now the asteroids belt. 🙄
