I happen to know this so I must comment for the glory. Cruithne was named for the Irish Gaelic term for the Picts, but this name "Cruithne" is actually the word "Britons" passed through centuries of cultural divides. The Britons were known to have called themselves the "Pritani" in very ancient times. Though the Celtic languages of the British Isles were split between two groups: the P-Celtic branch, in Great Britain (and Gaul), and the Q-Celtic branch in Ireland. As a result the ancient Irish rendered "Pritani" as "Qritani", which when passing through centuries of linguistic mutation gave "Cruithne" in later forms of Irish. It is not known whether the Picts referred to themselves with any such word or not, but the Irish obviously saw them as "Britons".

xøñχt is right. The name of our moon is also Moon. It is formally named that. Luna is not the scientific name you'd read in journals. The contestants (if you can call them that on here) didn't seem to know this fact. They seem to be pointing out that it's called The Moon because it's the only one, not that it's also its official name. You could say that the Moon is a moon. But that wouldn't be quite formal. It's defined as a natural satellite. I also agree with the comments here that IAU comes up with the weirdest and often useless arbitrary rules. Hence so much confusion about the moons, as evident with this video.

Michael from the moon's point of view, the Earth also orbits the moon. I.e., In relativistic terms, if you were some distance away from both bodies, and you focused solely on the moon, then you would see the earth seemingly rotate in orbit fashion around the moon. The fact that the barycentre is within the Earth's radius is somewhat the relevant in this statement. Ok, so you could say that the Earth is a still body in this relationship, and the moon a spiralling body, and that would be sort of true (apart from the small wobble of Earth created by the moon's gravity as it rotates around the barycenter). I guess one must make the definition and the distinction of a moon as opposed to a naturally orbiting satellite like a large asteroid. In the same way, you must make the definition of a planet or planetoid different than a comet, say, like Halley's Comet, even though they are both celestial bodies that orbit the sun. Many of the asteroids floating around in our system, aren large orbits around the sun, but many are in horseshoe orbits around the various planets as well, giving them a quasi-orbital nature. But you wouldn't call them moons, any more than you would call them planets. That's why distinctions and definitions in the astronomical world are so difficult, and why people try so hard to define them with rules. It just gets confusing in the end, especially for kids at primary school. It's probably best to just keep it simple for them, and define a comet, asteroid, moon, planet and a star in simple defined forms. And leave it at that.
@rtg_onefourtwoeightfiveseven5 жыл бұрын
@@RB747domme That's a silly argument. In relativistic terms, you could apply that to any rotating body and say that the entire universe orbits it. The barycentre is in fact the defining part of this statement, and what makes Luna 'a moon' but Charon 'not a moon'. Halley's Comet is so defined because it originates in the Oort Cloud.

@@nugagim It would not be a binary system then. To my knowledge, every set of orbiting star systems with multiple stars never have the center of orbit within the radius of one of the stars which is why theyre always binary systems. Im not even sure if its possible due to the necessary mass range required for an object to be a star and the mass limit of how big a star can be before it collapses in on itself.

The actual answer is that the Earth and moon together orbit around a point inside the Earth, so the moon is not a planet in its own right. No other near earth object has a stable orbit with the Earth, although Cruithne and some other objects do orbit the sun at times extremely near the Earth. 2010 TK7 is at least locked in position by the earth, but 2 months ahead of us in our cycle, so not particularly near to us. Oh, and there are tons of manmade satellites up there too.

The problem with this question is that Mr. Frye is using newly, or recently published theories. With astronomical, or celestial bodies, astrophysicists must come to an agreement on a term before it is accepted. And that could take ten years or more. Just because it has been published (that is the job of most researchers) does not make it a solid theory or even a valid theory. The academic world will them tear that theory apart for years, and if it still holds up over time, then the community will start giving it more credence. But to give it credence from the start, as Mr. Frye often did on this show with many things, is irresponsible. It is true that the definition of a moon is loose, but for most Astrophysicists, anything with a diameter smaller than about 30 km (app. 20 miles) is an asteroid. True, there are thousands of them orbiting the earth, but to confuse people by calling each of them a moon is ridiculous.

Well the moon and earth don't orbit eachother but they orbit a gravitational point between the moon And the earth where i believe is the place where both gravitational pulls level each other out

What you're thinking of is called the "barycenter". The barycenter of the Earth/Moon system is about 1000 miles below the Earth's surface

5:35: But they HAVEN'T. That was the argument for keeping Pluto a planet. Both pluto and earth haven't cleared their celestial neighborhood.

On that basis, none of them have, doesnt every planet in the solar system have moons?
@Gwydda6 жыл бұрын
No, neither Mercury nor Venus have any moons. And for that matter, nor do Ceres and Makemake.
@gavinkemp79206 жыл бұрын
yeah but ceres and makemake have failed in clearing the neighborhood of celestial object since one is in the asteroid belt and the other is in the kuiper belt.

I'm just gonna add, a year later, cuz I'm a year smarter now; For a binary planet, the center of gravity would have to be equally between the two planets. For example if the Earth was at the same distance as the moon from venus, then it would be a binary planet, because both Venus and earth would revolve around their combined COG.

The problem is that two out of the three criteria the IAU settled on (BTW, without consulting any planetary scientists) are so badly written as to be effectively useless. Criterion 3 is bad because how cleared is "cleared" and how big a body's "neighborhood" is have never actually been defined. By some of the proposed criteria, Mercury wouldn't be a planet if you put it where Pluto is, because it wouldn't have cleared it's orbit. And under criterion 1, there aren't just 8 planets in the Solar System-there can only be 8 planets in the entire Universe. Criterion 1 says a planet must orbit the _Sun_ . Not "a star", but _our_ star. So all those "exoplanets" that Kepler has found? None of them can actually be planets, because they don't orbit the Sun. The IAU wanted to come up with criteria that eliminated Pluto, so they slapped something together and called it good. There are valid reasons for saying Pluto shouldn't be grouped with the classical planets, but the IAU definition is just crap

The tiny objects that could be labeled "satellites" are not the same as "the moon". There is only one satellite in orbit around the earth that is 1/6 its mass. And that object is "the moon".

The real answer is "one". Words mean things. The show is playing a game of semantics because the official astronomical definition for "moon" isn't precise enough to exclude all the tiny, erratic objects moving around the solar system. As far as the **colloquial** definition, people *know* what a moon is. We wouldn't consider every random rock or dust particle around earth to be a moon.
@almostfm6 жыл бұрын
Well, we _could_ call a "random rock" a "moon", depending on what it actually orbits. If it actually orbits the Earth (or to be technical, if the body and the Earth orbit a common barycenter), then it would be a natural satellite of Earth. Both of Mars' moons are smaller than a medium-sized city, but nobody has a problem with calling them "moons", while Jupiter has moons smaller than that

I could swear that under a certain size they just called them "natural satellites". I swear that was in my astronomy course.

Exactly. What we decide to label something has no bearing on the the object itself. It only has to do with how we organize information.

I just knew one of the answers was going to be akin to "less than we thought because we've decided to call it something else!" just like with calling Pluto a planetoid.
