How many moons does earth have? - Qi - BBC

[JohnHutch]

Fascinating.

[Jinky1888]

this is not in least bit funny, incidentlly, Stephen Fry is a homosexual old man who analy lust after you men...FACT

[ChainsawVsGod]

@Jinky1888

And?

[Ub3rSk1llz]

@Jinky1888 right...

[purplechoc72]

@Jinky1888 Well done.

incidentally, you're a raving bigot who doesn't realise that QI viewers are generally intelligent enough not to care about someones sexuality... FACT

[Kabitu1]

I love Rich´s response at 1:16. "I call bullsh*t on this one, Stephen!"

[JaykSzarii]

I'm with Rich Hall on this one. :P

[iiSPARKx]

I know that it ain't water in Charlie Sheen's bottle.

[OhMyGodAWhale]

Wait, this isn't Professor Green..

[MattMetalMayho]

@spanieldencer1 That's because QI dose actually talk a fair amount of rubbish. I love the show and everything but not all of what you hear on it is 100% right, they just know everyone will believe Mr Fry so say whatever they like

[Arthur61987]

One of the definitions of moon is: A natural satellite revolving around a planet.

[MomoTheBellyDancer]

The correct answer is, of course: cheese puffs.

[blender124]

I know wikipedia is not a scholarly place for information but to quote the site "It has been incorrectly called "Earth's second moon", but it is only a quasi-satellite".

[Spanieldencer1]

Agree with the 'Cruithne is no moon' people. It's a Quasi Satellite orbiting the Sun and overlapping Earths orbit... Unfortunatelly, QI fail here.

[xTheGerbilx]

because

it was discovered

in 19

90

f*cking

4!

I love you Fry

[Udany147]

um, it's one.

[vtc193]

"One" is wrong but the cheese part is right I guess.

[RandomoGaming]

Dancing in the Cruithne light.. everybody's feeling warm & fine... lol

[cr9527]

Cruithne orbits the sun, not the earth. so QI Fail.

[slightlyinsaneFTW]

Personally I preferred Douglas Adams' book "So long, and thanks for all the fish."

And if ever anyone discovers what the universe is for, and why it is here, the answer must be 42.

[limpy601]

If the Earth has two moons, it must also have one moon, so Alan was right after all.

[slightlyinsaneFTW]

@limpy601 True.

[OktoberSunset]

didn't even get the year right! It was discovered in 1986. What a numpty.

[ytmoog]

@OktoberSunset

It's orbit was not identified until '97 though. So it was discovered to be a sort of moon then.

[Ravage017]

i love how everyone in the comments section feels the need to write in grammatically correct sentences with full punctuation after watching QI xD

[MrDudeBoiMan]

It's not a moon and it wasn't discovered 1997.

[Wakka12321]

Cruithne is a asteroid

[patrick112590]

Hahaha I love how whenever I'm down, this show always cheers me up.

[hammereddulcimer]

That's no moon.

It's a space station.

[Gewath]

Earth has a large amount of moons. Any debris that orbits it that doesn't come from humans is technically a moon. Unless one can determine the insanely unlikely condition that no other natural debris of any size (down to single subatomic particles) than 'the moon' orbits the Earth, Earth has a large amount of moons - potentially in the thousands, millions, billions, trillions, quadrillions, etc..

[rysliv]

cruithne orbits the sun, and its not a moon.

[mrchrisdavis09]

According the Wikipedia, "Cruithne has been incorrectly called "Earth's second moon", but it is only a quasi-satellite. Cruithne never really goes around Earth, and at times it can be seen on the other side of the Sun."

[kalslater]

Cruithne is not a moon it is a quasi-satelite. Quasi-satelites orbit the sun on the same path as another planet (in this case Earth), it is not a moon as it does not orbit the Earth

[evrekoa]

@kalslater Nice wikipedia work.

[SlamageEntertainment]

Cruithne is not a moon, but is a Quasi Satellite

[RavenDestroyer]

@SlamageEntertainment Next season The question repeats and then is 5-1

[blondemario]

@SlamageEntertainment A satellite is a moon, so Cruithne is a moon :P kidding kidding

[SackFulloApplez1993]

@SlamageEntertainment hug*

[CultureShockSix]

@SlamageEntertainment Cruithne is no moon.

It's a space station.

[jochum334]

@SlamageEntertainment they corrected themselves in a later episode

[Layla5915]

@SlamageEntertainment you're four years too late with that ;)

[jackn877]

@SlamageEntertainment yes they explain this in a later series

[1993gandy]

Why did they bleep out fucking but not shit

[latias600]

@1993gandy Shit is more acceptable in Britain.

[spock101010]

I liked this as soon as I heard "Dougals Adams"

[mrtoucantango]

Quick question please! How can something be see from the earth when its on the other side of the sun? The sun is in the way.

[anissab]

@mrtoucantango objects in space don't remain in the same spot (they generally always orbit something), so it isn't always blocked by the sun!

[Gewath]

@mrtoucantango It'd be easy if it was a much bigger star that was just right behind it.

If not, you'd have to look for an impact on objects away from the Sun (reflection of light (like a mirror), gravitational pull, a recorded image, etc.) (it could be a spaceship shot up from Earth).

Theoretically gravitational bending of light will enable you to see something that's physically behind another object, though it's infeasible to actually observe something behind the Sun this way.

[ThePrimaleon]

@Gewath How long have you been a moron?

[Gewath]

@ThePrimaleon Your mother.

*runs off in triumph*

[Gewath]

@ThePrimaleon Lots of objects are hidden by the Sun. Not all the time, but that wasn't the question.

Why would my mother have sex with you?

[Gewath]

@ThePrimaleon ...regret that remark.

I'm sorry I referred to you as retarded chimp with brain disease, regardless of whichever words we exchanged before that point and whichever disagreements may lie between us.

[7CellarDoors]

@Gewath That actually made me lol, I do not know why.

[AustinGerassimos]

not true... 3753 Cruithne ( /ˈkrɪnjə/, from Old Irish [ˈkrɪθnɛ]; Modern [ˈkrɪhnʲə] or [ˈkrɪnʲə]) is an asteroid in orbit around the Sun in approximate 1:1 orbital resonance with the Earth. It is a periodic inclusion planetoid[What does this mean?] orbiting the Sun in an apparent horseshoe orbit.[2] It has been incorrectly called "Earth's second moon", but it is only a quasi-satellite.[2] Cruithne never really goes around Earth, and at times it can be seen on the other side of the Sun.[3]

[EdgyXD]

Lol great video. It was actually discovered in October of 1986.

[MrDistrugator]

The Earth only has one moon, but it has tens-of-thousands of satellites (both natural and man-made) including the planetoid '3753 Cruithne'.

[Bidon45]

@kayper54 because its not SPELLED in english, you dolt.

[Katalyzt]

Actually, Cruithne is not a natural satellite as it does not orbit the earth like the Moon does. But in fact it is a quasi-satellite as it actually orbits the Sun, a but periodically come close to the earth as both their obits are exert a gravitational influences on each other(which is otherwise know as orbital resonance).

Katalyzt

[Mx41204]

And this episode was aired in TWO THOUSAND F***ING THREE. Get off of Stephen's back already. The show's admitted its been wrong before.

[dantrizz]

I want to know how many of the people who have obviously copy and pasted the wikipedia entry for Cruithne know what they mean when they say "quasi-satellite"?xXx

[GeorgeNorfolk1]

It doesn't even orbit the Earth, it orbits the sun.

[kanakaken]

It is a periodic inclusion, orbiting the Sun in an apparent horseshoe orbit. It has been incorrectly called "Earth's second moon", but it is only a quasi-satellite of our Earth. Cruithne never really goes around Earth, and at times it can be seen on the other side of the Sun, but only if you wear a really good pair of sunglasses. Stephen Fry's minders have made a mistake.

[flaviusclaudius7510]

You'd have to be really generous / obtuse to define moon in such a way as to give Earth more than one.

[dvnt808]

It has been incorrectly called "Earth's second moon", but it is only a quasi-satellite. Cruithne never really goes around Earth, and at times it can be seen on the other side of the Sun.

[Misteryman94]

Cruithne is not a moon. It's a periodic inclusion planetoid orbiting the Sun.

[scarletharlot69]

cruithne is indeed a co-orbital not a moon. fail Stephen

[Orpheelover]

I told my geography teacher that the earth has more then one moon and she didn't believe it. She told me I have to find proof. If anyone has another god source about this please tell me before Wednesday the 7th of December

[Kamakazie27]

@Orpheelover It doesn't. The thing they're talking about here actually orbits the sun, not the Earth.

[Orpheelover]

@Kamakazie27 So it's just called the second moon even though it's not a moon. That's confusing. Well I'm half right, there is a second moon it's just not a moon. Now I won't look like a complete idiot at school :D

[Kamakazie27]

@Orpheelover It isn't called the second moon at all, it's called Cruithne. Stephen's explanation in this clip is incorrect. Look up Cruithne and you shall see.

[Orpheelover]

@Kamakazie27 Oke now I look like a complete idiot. Let's hope my teacher forgets that I said that.

[de5188041]

"Blue moon i saw you standing alone.. not with a small friend!"

[Babyhowdy233]

(cont.) It was not until 1997 that its unusual orbit was determined by Paul Wiegert and Kimmo Innanen, working at York University in Toronto, and Seppo Mikkola, working at the University of Turku in Finland.

[Babyhowdy233]

Actually, Cruithne was discovered on October 10, 1986, by Duncan Waldron on a photographic plate taken with the UK Schmidt Telescope at Siding Spring Observatory, Coonabarabran, Australia. The 1983 apparition (1983 UH) is credited to Giovanni de Sanctis and Richard M. West of the European Southern Observatory in Chile. (cont.)

[Babyhowdy233]

It has been incorrectly called "Earth's second moon", but it is only a quasi-satellite. Cruithne never really goes around Earth, and at times it can be seen on the other side of the Sun. Cruithne's orbit takes it inwards towards the orbit of Mercury, and outside the orbit of Mars. Cruithne orbits the Sun in about 1 year, but it takes 770 years for the series to complete a horseshoe-shaped movement, with the Earth in the gap of the horseshoe.

[gir908922]

LOL! Gotta love Stephen Fry and Alan Davies.

[LudicrousPlatypus]

I LOVE QI! 

[mayo2t]

199*!@*#4 AY?

[AJToad]

Cruithne's an astroid though...

[HBKRichie]

Thats no moon!

[slipperywhenwet5]

It's actually a Quasi-Satellite, not a moon.

[smitty01209]

@slipperywhenwet5 Wikipedia ftw.

[lashlashlashlashlash]

its not a moon anymore though..

[Napier931]

BECAUSE IT WAS DISCOVERED IN NINETEEN NINETY F***ING FOUR!

[mahound9]

As it turns out, according to Wikipedia, there is only one moon. Cruithne doesn't rate.

[latias600]

@mahound9 Wikipedia can be edited by anyone so its not a credible source.

[TheDhezballah]

@latias600 It's almost always right.

[Orberror404]

@TheDhezballah Almost always =/= Always

[fauxshizl]

@Orberror404 Almost always=credible, however.

[TheDhezballah]

@Orberror404 Not even science books are going to be always right, my year 12 human bio book had wrongly labeled the tibia and fibula in one image. Everybody makes mistakes but the thing is if that same thing had happened in wikipedia it would have been fixed in minutes while my science book would be wrong until the next edition.

[Orberror404]

@TheDhezballah Did not say science book were always right. but wikipedia isn't either.

[Zulluhead]

@Orberror404 Actually, Wiki is extremely accurate on Mathematics and Astronomy. I know this as my university lectures for both have stated that it is the best source for the 2 and it has never been wrong to their knowledge.

[Orberror404]

@Zulluhead Extremely accurate =/= always accurate.

[Keldrath]

@Orberror404 you should try googling "accuracy of wikipedia"

[Orberror404]

@Keldrath That doesn't stop vandals attacking wikipedia.

[Keldrath]

@Orberror404 it happens occasionally, most pages are restricted so vandals cant modify them and the ones that arent their vandalism is edited away nearly instantly.

[Gewath]

@Orberror404 Extremely accurate also ≠ monkey with banana. Care to make relevant statements?

[etbadaboum]

Who are the guests? Thanks in advance.

[LittleBabyBum]

I'm the moon!

[tooncanada]

It's actually a quasi-sattelite, NOT a moon... The Earth has only one moon

[imborgoss]

@tooncanada even better there is only 1 moon in the univers becouse the moon is a natueral sattelite so wel there is only 1 moon only we are starting to use the word moon for stuf that isnt the moon

[OperaticIronman]

@tooncanada it was also discovered in 1986

[loopstheloop]

@tooncanada yeah.... so fuck you, fry!

[ChainX]

@tooncanada

Rather splitting hairs. A moon is defined to be a celestial body that makes an orbit around a planet. So obviously, the definition, and hence the name, fits just fine. A "Satellite" is simply another name for a moon, and vica versa.

[acr08807]

@ChainX Cruithne does not orbit the Earth.

[ChainX]

@acr08807

This is true. Still, I find the distinction between "Quasi satellite" and "satellite" to be highly arbitrary. While I understand that the distinction is necessary, and that the type of Orbit Cruithne takes is quite different than our Moon's, the major defining factor seems to be that Cruithne will eventually leave it's orbit, or rather, it's orbit changes often. Seeing as our moon will eventually leave our Orbit, I fail to see a grand difference.

[acr08807]

@ChainX The Earth does not remain close to either elliptical focus of the orbit of Cruithne. I suppose it is arbitrary, because there are no perfect orbits when you have three celestial bodies interacting, but we have to draw a distinction somewhere and, in this case, it's not even close. I hate to point anyone to Wikipedia, but there's an animation of the orbits of Earth and Cruithne relative to the Sun in the "Quasi-satellite" article there that illustrates this perfectly.

[acr08807]

@ChainX I just looked at the Cruithne article, and it's got two excellent graphs, one that illustrates Cruithne's and Earth's motion around the Sun and another that shows Cruithne's motion relative to the Earth. I guess that, once in a blue moon, Wikipedia proves itself useful.

Would so love to see Sean Connery on this show.

[Libertarianist]

Cruithne is a co-orbital asteroid, not a moon, it does not orbit earth.

[itak365]

Oh, God, the moment he mentioned Restaurant at the End of the Universe, I immediately imagined him as the Guide.

[icak9]

that's not a moon; it's a quasi-satellite. if you include it as a moon, you would also have to include the other quasi-satellites. i think there are about five in all. so, still, the answer wouldn't be two.

[arachnophile01]

Cruithne has 1:1 orbital resonance with the Earth, meaning it completes one orbit approximately every time Earth does, but orbits tha Sun. But it's hard to put that on a quiz show creatively, sooo.

[Kepahl]

Were they excluding all the Moons in Korea?

[TheThewonderman]

the earth has one moon and the so called other moon is actually not a moon it is an asteroid that orbits the sun and if you want to know more go to the universe today website and look for how many moons dose the earth have

[DarkShaDowHooD]

So all the planets are moons because they orbit around us ,also is that the planet x that is over dramatized .

[damilksta]

@DarkShaDowHooD Are you retarded?

[DarkShaDowHooD]

@damilksta No Just acting out that I am .

[ImperialGeorge]

My God, Stephen Fry was wrong!

Its not a moon it's merely a qausi satellite.

[Keownolomio]

Exactly... "Who comes up with this shit?"

[TheOrangeGrooveJanet]

If it has two moons, then technically it also has one moon.

[reksub10]

the earth does have 1 moon ,thats the trick question like how many months have 28 days and people shout 1 and the truth is 12 month have 28 or more ...so was alan wrong ,,,he was QI wrong but technically correct

[Ryakki]

@reksub10

No, he was just correct. Cruithne isn't a moon. It doesn't orbit the earth, it orbits the sun, and just happens to hang out with the Earth a lot at this point in time. That doesn't make it an Earth satellite.

QI is indeed quite interesting, but you can't take anything it says at face value. Its' fact checking seems quite poor.

[reksub10]

@Ryakki yeah the show is awesome and ive always thought their researchers are on wikipiedia lol ,but in this show there are 5 comedians so the questions are based around making good funny T.V. imo

[Ryakki]

@reksub10

Wikipedia has the correct info :P

[danielbudzynski]

for the first time I don't give a shit that its 240p. It's Stephen Fry

[CarbonFiberDuck]

They orbit the sun and are asteroids

[CrapTurret94]

It's called, "The Moon!"

[retrogamerist]

Its automatically right because Stephen said it.

[xXLuciferDarkheartXx]

"It's called THE MOON!"

Can't argue with that, it's quite a good point.

[otherranger]

@xXLuciferDarkheartXx The Moon's name is actually "Luna"

This is why it was called the 'Luna Lander'

[LordKombox]

@otherranger Lunar. There is no official name, it depends on language.

[otherranger]

@LordKombox Yes Lunar, thanks I missed the 'r'. I believe it can also be called Selene, however this is not a very common name.

[NZMyrmidon]

@otherranger Selene is actually the Greek goddess associated with the moon, the Roman version of her is Luna, which is quite obviously where "lunar" comes from considering a lot of their gods were personified concepts of natural features, with their name literally meaning the thing they "rule" over you are pretty correct with Luna, that being the Latin.

[hempartist420]

it is a quasi-sattelite... not a moon

[InferParadise]

There is only ONE MOON IN THE UNIVERSE, because objects that orbit around planets are called "satellites".

[lcyw20]

@InferParadise Actually, "moon" is often used to refer to other natural satellites of other planets.

[InferParadise]

@lcyw20 That may be, but it's not the technical term

[DarthGarz]

Yeah, Cruithne is one of 5 "co-orbital asteroids" and is not actually a moon.

[DrMazgaN]

any1 knows where to find qi episodes for DL/just watching like here, but WITH ENGLISH SUBTITLES?

english isnt my native language so its hard to get some of the slang and jokes there =( and youtube's subs from sound system sucks...

plz help!!!!!!!!!!!!!!!!!!!!!!!!!!­!!!!!!!!!!!!!

I NEED MY QI DOSE!!!!!!!!!!!!!!!!!!!!!!!!!!­

[marlboroman1985]

It orbits the Sun not the Earth, so how the hell is it a satellite of Earth? That's just crappy research.

[Chrisfs59]

What is the definition of a moon in that case? If it's anything that revolves around the Earth with any kind of orbit, then Halley's comet counts as a moon since it orbits every 75 years

[juditK2007]

@Chrisfs59 Halley's comet orbits the Sun not the Earth. The fact that it can be seen from the Earth doesn't mena it orbits the Earth.
