Moons are a common feature throughout our solar system, but two of the major planets don't have them, Mercury and Venus. It's easy to figure out why Mercury doesn't have one, it's too close to the sun, but Venus on the other hand is harder to explain. Did our sister planet ever have a moon? If it did, then what happened to it? What exactly were early astronomers seeing that led them to think there was a moon? Was it actually a moon or something else? In this observation we'll attempt to find the clues to help crack the case of Venus's missing moon.

Just curious...are you ill, sir? You sound as if you are having breathing trouble throught this vid.
Cool vid, BTW.
@@Sennmut I may have had a cold, I can't recall. I do know I was still using a shotgun style mic at this point and it would pick up a lot of ambient noise. Thanks for watching!
I feel lucky to have found this. Really good information that's presented in a way that holds my attention. Best of all, I'm actually learning things that I didn't know
Thanks! I really appreciate hearing that.
I like the clear effort to provide similar production quality as tv documentaries in the past & now. Well done please keep it up💕
Thanks! It has always been a goal of mine to reach that level. Slowly but surely the episodes are getting there.
@@RooftopsofAmerica After being visited by Neith the goddess herself I found my way back to this video!!! I was surprised I’ve already been here lol💖💖
@@OGseoulite Welcome back!!!
I love how you sound just like Neil Tyson. You definitely need some Alan Silvestri in these videos!
Thanks! That's my first Neil Tyson compliment! I've heard Marty Stouffer and even Neil's Cosmos predecessor Carl Sagan but never Neil Degrasse Tyson before. As for Mr. Silvestri I probably couldn't afford the music rights! Cheers!
Really appreciate this one!! Never heard of most of this and have always fancied myself an astronomical enthusiast!
I'm glad you liked Steve! It's fun exploring these little oddities of space exploration.
My theory is that like Mar's moon Phobos and its degrading orbit, Neith's orbit recently degraded to the point that it broke apart because of gravitational strain and impacted the surface of Venus at a low trajectory, thus causing huge gouges that over the intervening centuries have filled with magma much like the Siberian traps but on a much larger scale. This could possibly be the cause of the hellish conditions on Venus's surface.
💯
That would mean Venus must have rings…
@@JaisalLakum
If the moon broke apart above the gravitational point where debris would not be pulled down to the planet then there would be rings. Also, depending upon the composition of Neith it could survive an eccentric orbit. A moon comprised of mostly iron and nickel would be much more likely to survive higher gravitational stresses than a moon comprised of loosely packed debris.
Great video. Just found about this whole Neith thing today. Super interesting.
You did a great job on these videos. Wstched each one multiple times now.
Thank you! More solar system episodes are on the way too!
@@RooftopsofAmerica Awesome, looking forward to them.
Just found your channel and I love it 😊
Thank you! More episodes are on the way!
What about the theory that Mercury was once the moon of Venus ?
This could explain the orbit of Mercury and the slow counter revolution of Venus.
Mercury may look like our moon but it is drastically different where it counts...on the inside. Its incredibly dense body, higher density than Venus, and evidence points it was larger at one point. Hard for a body the size of Venus to be able to capture and maintain a body like that in orbit without the destruction of both.
@@RooftopsofAmerica yep, meercury may have been a neptune sized gas giant that just burnt down to nothing in the end.
Well done and presented. Thank you.
Thank you, I appreciate it!
I'm impressed with this informative video about the moon of Venus.
This is great thanks! It sounds amazing at 1.25 speed.
Very nice video, really relaxing and informative
Thank you! If you enjoyed this one check out the rest of the Rooftops of the Solar System series!
That was really interesting. Thanks!
You're welcome! Thanks for checking it out!
Enjoyable video. Thank you.😃
You're welcome! Glad you enjoyed it!
I hope Neith will somehow turn out to be real. And habitable. Wouldn't that be nice?
Could it not be the case that Venus did indeed have a moon but due to an unstable polar orbit it was flung away, either into the Sun, or into deep space, sometime around the C18th?
Wouldn't a large body orbiting a planet perpendicular to its rotation bleed it of angular momentum? Particularly if the orbit isn't aligned exactly with the planet's poles, and is cocked at an angle, like our Moon's 5° orbital deviation from the Solar ecliptic?
Perhaps it is the case that Venus did have a circumpolar orbiting moon that bled off Venus' rotational inertia, and when Venus was rotating at zero velocity, essentially tidally locked to the Sun, the overall momentum within its system was so sparse that its moon simply drifted away, its final yank at a skewed angle tugging Venus into its current achingly slow backwards rotation.
You deserve more subscribers.
I appreciate that! I'll admit I could be better at promoting my work.
underratted channel
Perhaps someday it'll breakthrough but right now I'll just keeping put out good content. Cheers!
Only recently found out about Mars moons
Kinda wonder in a different universe where Earth's sister actually had a moon. What would it look like? Thoughts?
That's a good question, one thing I don't think it would be is the size of our moon. It's an anomaly in its own right. I think it would be smaller in size, probably more like Mimas or Proteus. As for its appearance I think that would be closer to how our moon looks with its craters and mare.
@@RooftopsofAmerica Reasonable speculation maybe if it did exist the Russians wouldn't have to see hell first hand! Heh.
Maybe like Phobos and Deimos too. A captured rock.
Yeah only like 4% of people know Neith existed 4.3 billion years ago. Neith collided with venus forever and there might be people who know about Neith more
IM STARTING TO THINK THEIA WAS VENUS'S MOON AND MAYBE EARTH DESTROYED THEIA / VENUS'S MOON MAYBE
What about planet Vulcan viewed by astronomers before and after 1800s, for centuries which was placed before Mercury?
You'll want to check out the Vulcan episode for more details on that!
Another mercury suggested merucru had a moon aswell
It.
There is one more intriguing theory as to the current whereabouts of Venus’s lost moon: it is hiding in plain sight. When it was knocked out of Venus’s orbit, it got caught up in the Sun’s hill sphere. It is the planet Mercury!
Planets without a spin cannot have moons
Hubble space telescope, and all the modern instruments have not seen anything.
Venus might have used to be habitable!
Wouldn't native moons be differentiated from captured moons by presence or absence of tidal locking? (I like the mountain man setup of this video)
Not necessarily, both Phoebe (Saturn) and Triton (Neptune), two suspected captured moons, are both tidally locked. As for the look, since this was a spinoff of sorts of my main serious I decided to keep the general style.
@@RooftopsofAmerica That's interesting. Now I'm wondering what scenarios lead to tidal locking and how the other planets got their native moons. Is it similar to our moon's creation with a rocky planet like Mars? As for the gas Giants is it a different process?
@@silaskuira9124 Tides lead to tidal locking. Typically the bodies undergoing tidal locking are elongated from spheres to elipsoids (though not usually visibly) with the pointy ends alligned to the orbiting partner. Any spin in excess of the orbital period tends to try to torque the long axis out of alignement, and the angular momentum of that spin gets bled off as frictional heating (Io), or by transfer into orbital angular momentum (Earth-Moon). Closer in orbits and fluid composition (lava, atmospheres, oceans) tend to accelerate tidal locking, and lighter bodies have less angular momentum and lock sooner. Our Moon locked long ago, and if our Earth-Moon system had 50 billion more years of tides transfering our day length into Lunar orbital distance we would lock to the moon with a day length of about 1100 hours.
@@NullHand interesting, that's classic entanglement. I wonder if by extension the entire solar system is slowly synchronizing all motions.
Maybe Mercury is the moon.
That's no moon. It's a space station.
Venus se esta atrayendo a la luna hacia el.
Got what I came for, so the goddess neith is associated with Venus
Why couldn't Mercury be the Suns moon
Maybe mercury is Venus moon
funny video... why not call venus non missing moon,,, zsaperth,, makes it more ' out there'
You'd have to take that up with Jean-Charles Houzeau since he originated the name for this hypothetical moon. Glad you enjoyed the video and thank you for watching!
Interestingly enough, the phrase 'interestingly enough' is one of the most cumbersome, unpronounceable and flat-out boring phrases in any language, and instantly loses the speaker any attention they might have commanded.

Earth have 2 moons 1 ITS moon 2 but i can not tell you 😐
Standing outside eh? Lame excuse.. and astronomers have been full of crap ever since.
