Saturn’s moons Janus and Epimetheus were once thought to be the same moon. It turns out they’re dance partners.

Admitting that you can’t boogie is slightly embarrassing, but to make you feel better I can’t either.
Check out horseshoe orbits, kind of the same idea.
As a child I had a Slot Car racing set with this Mechanic, my younger brother and I purposely crashed the cars and tried to know the OTHER car off the set.
We were stupid and young.
Now we're just stupid 🙂
Most an agree that two wrongs, don't make a right. But if all the hosts and viewers who can't "get down and boogie" all got together to fail together at boogieing, would we actually manage to get down and boogie? How may wrongs does it take to make a right?
👍
LOVE the Tshirt!
I don't know how to "Get down and Boogie" either hahahah ..
Huh… pretty sure these were in an episode of MST3K….
I thought that segue was pretty good!
🤯
Like in roller derby where the blocker throws the jammer forward to score more points quicker.
So… …how long until they impact?
JAnus is huge
They must be in a rush to get to work.
Voting for a boggie in the next video!!
Does these moon's particular situation means that they are gradually destroying each other?
Horse's are cool
What you get 'Down' and boogie? I usually just rolll 'Up' my boogie, and flick it into the trash, or like in school put it 'Under' the desk… 😉
You don't have to know how to get down and boogie to do it… you just let it happen and have fun.
Yes!! I've been waiting for YEARS for sci-show to cover this because I KNEW they'd do a great job. Thank you Sci-Show!
Get Savannah a raise so she can visit a dance school in order to boogie ! 🙂
Will these moons just eventually merge?
motion before the science court to rename Epimetheus to "Joplin"
I need to get over my thing of not watching if Hanks not hosting
I am pretty sure I saw an episode of Star Trek TNG during one of Data's after dinner chats where he talks about something like this
Savannah!!!! Love their voice and the dry wit Science jokes they deliver! My third kid is non-binary and representation matters! 🎉 Keep rocking the science!
When I heard the intro saying "this SciShow video," I thought for a second it was "this sh**-show video." I guess I had that on my mind!
Very interesting subject, and I loved the visuals for it. Thanks for always bringing the great content
Super cool!!
So aren't they just orbiting each other?
I prefer j-anus…you say it weird
Janus is actually an alien surveillance probe that had seen enough and left for home. An ice mining ship chases it down and falls into a slipstream created by the superluminal drive of the artificial moon. Having no option but to land on the moon and make an attempt at survival, the ship and crew are swept across the galaxy to a structure as big as the solar system where they meet a divergent group of civilizations trapped inside the structure. Help arrives from the future in the form of a hyper dese cube containing a simulation of the protagonist's descendants. Alistair Reynolds' Pushing Ice, an unusual stand-alone novel, takes advantage of this unique property of Janus and exploits it to the readers pleasure. Highly recommended.
Musk and his precious fans will demonise you girl
because you are living your best life
you show em
They’re really just slingshotting each other around Saturn.
Savannah: The more they host, the cuter they get, I swear
yikes
Out of all of the musicians ever, you choose… Coldplay?
I bet Janus's first name is Hugh
They take turns being 'big spoon' and 'little spoon'! 🙂
I still want a moon orbiting a moon.
sounds like the a horseshoe orbit
Uranos has also at least two moons that do that vortex/corkscrew motion together!
these perfect mechanisms are the reason of Saturns perfect magnetic field.
Naming a moon with an orbit like this after the two faces god seems like an incredible coincidence. So much so, that I suspect that Andouin might have been on to part of the story. Maybe he saw both moons in the same orbit and thought they were one and the same despite looking different? I mean, it's a bit farfetched, but if you ask me, so is assuming it's a coincidence without any evidence for that (I have not checked if evidence exists, just going off of how it wasn't mentioned in the video).
Hi Savannah!
Dance like the moons of Saturn!
So basically, what you're saying is these two moons do a do-si-do every four years?
That is probably the most beautiful dance I've ever seen!
So glad that SciShow presenters get to show their personalities. The "boogie" tag at the end was pure delight.
