Are We about to Discover a New Planet in Our Solar System?

"Known as Planet 9" Pluto, quietly in the distance: "Booooooo!"

Simon gets way too much enjoyment out of the Uranus jokes 😂

I keep getting so happy when I find more Simon channels.

I can't say how much I love when I find a brand news Simon channel. Excellent

I'm trying to convince the scientific community to call planet 9 "Tantalus:" son of Pluto and always just out of reach; pretty good, right?

Writer: "Should we be serious or make jokes?" Simon: "Yes."

This is like his 15th account 😂

Astrographics is a channel I didn't know we needed, but I'm glad we have it.

5:15 "The gassy glory that is Uranus." Niiiiiiiice

"Ever since Herschel stared hungrily at Uranus.". Dying!

I still love the fact that we can study planets millions of lightyears away, see galaxies and stars billions of lightyears away, literally glimpse into the past with our incredible technology.... and we still can't determine if there's a 9th planet in the Kuiper belt after all this time lmfao

Makes me think of the theory of Nemessis in the 1980s and early 1990s, where Nemessis was supposed to be a stellar companion of the Sun orbiting it in ~26 000 000 years. It would be so far that it would resemble a normal star, around magnitude 12, with a very small proper motion, and small enough parallax (although larger than the parallax of Proxima Centauri, our closest neighbour star) not to be visible unless accurately measured. It would have been one the ~1 000 000 stars of that brightness in the sky, but no one knew which one, and at that time it was unfeasible to measure 1 000 000 parallaxes. Now that Gaia measured accurate positions and parallaxes of 1 700 000 000 stars, we know for sure that Nemessis does not exist.

In 1997 in school I learned about a possible "Planet X" (for 10 when pluto was still a planet) and that its discovery was "Just a few years away" so they have been looking for it for a long time and I'm still waiting.

...."the majesty of Uranus"... absolutely brilliant

Oh, the Uranus jokes 🤣😅 never get old 😅 "probing Uranus" left me in stitches 🤣

Where the Nibiru boyz at?

Due to recent economic downturns I regret to inform you that we are not accepting new applicants at this point in time. We appreciate your interest in our solar system and will keep your application on file and will contact you if any openings suited to your abilities should arise. We wish you well in your future endeavors

Astronomers: "We can't find Planet 9." Simon: "Have you checked Uranus?"

I have to admit, I'm rooting for the black hole hypothesis. Think of the research opportunities something like that would provide. Downside is, finding it in the first place would be extremely difficult and would require a completely different set of methods for detection, involving trying to determine the object's orbital trajectory and then looking for microlensing events that match that orbit.

5:16 "Gassy glory that is Uranus" I see what you did there Simon 😂 7:15
