8. What Is Eris?
Depending on your familiarity with our solar system, you may or may not know about Eris, and for good reason based on its location and how it relates to other planets and celestial objects in the system.
In short, Eris is one of the largest known dwarf planets in our solar system. For those who don't know, a Dwarf Planet is one that has the size and shape of a planet but fails to meet certain technical qualifications to be considered a full planet. Eris is about the same size as Pluto, but is three times farther from the Sun. Making it something on the very edges of our solar system. In fact, outside of some comets that have been discovered and a "unique object" from 2018, the two are the most distant known objects in our solar system.
Eris first appeared to be larger than Pluto. This triggered a debate in the scientific community that led to the International Astronomical Union's decision in 2006 to clarify the definition of a planet. Pluto, Eris and other similar objects are now classified as dwarf planets.
Originally designated 2003 UB313 (and nicknamed for the television warrior Xena by its discovery team), Eris is named for the ancient Greek goddess of discord and strife. The name fits since it remains at the center of a scientific debate about the definition of a planet.
7. The Discovery Of Eris
Given all we just told you, the discovery of this dwarf planet is really significant.
Eris was discovered by the team of Mike Brown, Chad Trujillo, and David Rabinowitz on January 5, 2005, from images taken in October of 2003. The discovery was announced in July 2005, the same day as Makemake and two days after Haumea (two other dwarf planets), due in part to events that would later lead to controversy about Haumea. The search team had been systematically scanning for large outer Solar System bodies for several years, and had been involved in the discovery of several other large TNOs, including 50000 Quaoar, 90482 Orcus, and 90377 Sedna.
The reason that Eris wasn't discovered right away via the images in 2003 was very simple, Eris was moving so slowly that scientists weren't able to detect it. The team at the Palomar Observatory had automatic image-searching software that excluded all objects moving at less than 1.5 arcseconds per hour to reduce the number of false positives returned.
When Sedna was discovered in 2003, it was moving at 1.75 arcsec/h, and in light of that the team reanalyzed their old data with a lower limit on the angular motion, sorting through the previously excluded images by eye. In January 2005, the re-analysis revealed Eris's slow motion against the background stars. Thus leading to its true discovery.
After that, the team dedicated itself to learning more about the soon-to-be-named dwarf planet, mainly learning what kind of orbit it had, and eventually learning the discovery that it had a moon within its orbit.
6. The Xena Name
I'm sure some of you out there were a bit curious as to why a scientific team would nickname a planet "Xena" after the legendary TV show featuring Lucy Lawless. Granted, that's not the name the Dwarf Planet has now, but the story behind this nickname is honestly rather unique to our solar system.
Due to uncertainty over whether the object would be classified as a planet or a minor planet, because different nomenclature procedures apply to these different classes of objects (which would lead to the demoting of Pluto not long after Eris' discovery and classification), the decision on what to name the object had to wait until after the August 24, 2006 IAU ruling. As a result, for a time the object became known to the wider public as Xena.
But why that one? "Xena" was an informal name used internally by the discovery team. It was inspired by the title character of the television series Xena: Warrior Princess. The discovery team had reportedly saved the nickname "Xena" for the first body they discovered that was larger than Pluto. According to Mike Brown, who was part of the team that discovered the dwarf planet:
"We chose it since it started with an X (planet "X"), it sounds mythological (OK, so it's TV mythology, but Pluto is named after a cartoon, right?), and (this part is actually true) we've been working to get more female deities out there (e.g. Sedna).

Eris, with its moon Dysnomia, is particularly fascinating
Why is that?
@@gatheringleaves because it is enigmatic since so little is known or even spoken about it
@@christiane.g.4142so it's niche, in a way. I'm so dumb I thought pluto was the only dwarf planet in our solar system 😂
@@owensanfordstuff Not nearly, there are also Haumea, Orcus, Quaoar, Gonggong, and Sedna much farther out
Can’t wait till they find an exoplanet as large as earth or mars that hasn’t cleared all orbital debris from its plane. Then we can sit back and watch the chaos all over again.
They should of defined dwarf planets by there mass or radius therefore this is likely not top happen again. ( I think 1000KM radius rule is easy to remember and scientific at the same time )
But if this happens it's likely we would entirely scrap the definition of planet. splitting it into terrestrials ( maybe dwarfs would join them or be called dwarf terrestrials ) and Gas giants ( which could be later split into Gas and ice giants ).
"we"
Very informative video… Thank you very much
Thanks for uploading. 👍
Another great video, thank you. I have recently heard of this planet(?) and it's bizarre orbit
planet 9 right?
Harder to study than Pluto itself but not less fascinating dwarf planet!!
THREE x further? Pluto is already ridiculously far that we couldn't see it clearly with telescopes it would take 25 years for us to get there. staggering to think about how wide the Kuiper belt is
Because they're so large and their orbits so odd it makes me wonder if they were once moons of the big outer planets that got launched out while the big planets were still sorting out their current orbits with each other???
That’s a good possibility.
We really cannot be sure what is bigger eris or Pluto I mean eris "seems" to be bigger but not 100% but I really want Pluto to win this
I love Pluto but I'm on Eris' side here
I'm on Eris side
Lucy lawless Eris the goddess of chaos get it? Mike brown has a good sense of humor along with watching far to much tv
Pluto is named after a cartoon?! Please check Greek mythology and try again.
I think it's named after both if I'm correct
yall showing Eris and showing pluto. That heart snow is Pluto!!!
Thank you! 👍
Your welkome Grab a Beer
Oh Eris.. my favourite dwarf planet :)
I wonder how long it took for the cameraman to get all those pictures. Must have taken years to go all the way to a dwarf planet and back!
No a simple 10 mile telelens is on a iphone is all you need..
He left his things behind
A rose by any name would smell as sweet
Looks like a captured satellite possibly from another star passing by 🤔
Interesting.
What qualifications do I need to be a Planet Namer? I want to work as a planet namer guy.
Find a planet and name it
My name is named after the dwarf planet Eris
Pretty cold planet. You would need one humdinger of a electric heater you lived there.
I heard of Sedna and Eris from a game I thought they were made up lmao
Lol they real
Warframe?
@@IndigoFeather yes don’t play to often tho
oohh. next week 100k subs? Well you deserve it! :)
Man like Eris Orbits the sun like he don’t care
That's awesome... what I want to know is if these dwarf planets are technically within the Heliosphere... I mean, they'd have to be to maintain solar orbit, right? Or am I on some bs?
Yes
Eris is actually a slight bit smaller than Pluto but more mass.
Dam this planet was named after me lol
What did you steal the graphics? Why does Pluto spelled as Pluton?
My name is Eris
Given the number of jf dwarf planets and some having insanely huge orbits, I would be very surprised if a moon, Nars ir even Earth mass olanet hs not out there at jesst 1,500 A.U. or more aeay ftom the Syn, probably in a very elliptical and inclined, even retrograde orbit.
The god Ciod is kind of like the western Qadosch; this helps understand the auspiciousness... Very similar are Bastet and Kamala, a small difference being that the two latter goddesses are only for heterosexuality. All of them are Thejerexzen, have therefore a special effectiveness. Dysnomia is also a Shade, not a goddess; the moon has influence related to the former arts format Opera, for one thing...
People say there are 32 planets in are solar system...|
My opinion I believe that we do have 32 planets, but we just have to find them...|
That probably includes dwarf planets and moons.
There are more than 32 actually.
Why don't they class planets like they do on Star Trek, Earth is Class M which I would Define as in the habitable zone, suitable for life and Orbits a star
Pluto was named for the Greco-Roman god of the underworld, not a cartoon dog. All of the planets (with the exception of Earth) are named for Greco-Roman gods. What is up with this channel?
my real name ist eris and in the shool we looked that
and thanks
Mij name is Eris
Pluto wasn't named after a Walt Disney dog. Clyde Tombaugh told me that initials PL stood for Percival Lowell, who was looking for a trans-Neptunian planet. Pluto was never a dog.
Me actually searching about eris because of EXO😂
Kind of odd that an astronomer would be so dumb as to think Pluto was named after the dog.
I had the same thought!
I don’t think he’s an astronomer.
Since this planet is so far out and has a weird orbit, is this the "Planet X" or "Nibiru" of Sumerian Folklore?
ahem. sedna is way further than eris.
sedna isnt a dwarf planet, its a large minor planet, and a dwarf planet candidate
Sedna is not further away then Eris at the moment. but in a few 100 years it will be.
I discovered a days ago that the fact of being discovered Eris they put a Pluto the category of dwarf planet.. disgusting for me
They thought Eris was bigger than Pluto so it was demoted. Then they figure out it really isn't but still leave Pluto demoted. I love science.
@@denkeyleeeris is still significantly more massive than pluto, with their difference in volume being negligible.
Am I a joke to you?
Chill its just a reply to the title
what part of the title are you replying to?
Eris is a particularly bad name for the planet- Xena was not a bad name; Quen is a name, or Releg. Eris is not a goddess, but a Shade. The god associated with the planet is *Ciod* . Wisdom is the astrological principle. Among divinities, only some open the traditional stoppage, associated with the Root Miasm of those American; stoppage prticularly in the 8th, The Nerthus Center; the place is Celandine Lok; the Energy is called Sefa. The god Ciod and certain others open there. In Yoga, which is not really possible for those with the national Mark, really only mantras and attunement which open where there is a stoppage are worthwhile; only divinities which do so. The Sacred Spirit has not been really possible for those who have the national Mark "American", neither for those who are Anglicized... Those of a dual deception, in other words. No religion has been possible from the beginning of the fllag made through most forbidden means. Things of Ciod- among liquors, Tequila is the only I know; among herbs, a water cress... naturally, intoxication is not necessary, most probably... The Shift is called Thejerexzen, onto the Path of a True Race channel; there is none called "American"...
A planet is still a planet whether dwarf, minor or satellite/moon.
it's still very undecided if dwarf planets are planets or not.
They are technically called sonic not dwarf , xzena
So... woke planet. Box checked
I note you haven't actually published the criteria for calling a body a planet. Much of the criteria are terribly arbitrary, THIS is why so many disagree with you and your bunch. It sounds like a bunch of astronomers wanting to get their names associated with the HISTORY of astronomy more than actual science.
*Eris CAN'T have a magnetoshpere!! It's TOO small and the core solidify LONG TIME AGO!!* 🙄🙄
if people could change to a planet to a dwarf planet, since we really dont know much about anything, how can i trust that what they say how the world was build many million years ago, is how the planet became a planet. when they werent there to witness it themselves. lol
Why named this planet from some stupid cheap tv show?
pluto was a god

You know what truly sucks? Those unrelated images and clips you add to this video because of your low opinion of your audience. After all, brain-dead viewers with short attention spans need constantly moving images to hold their interest.
The content itself is mildly interesting and seems to be directed at late middle school to early high school students
