	I propose that Luna be accepted for Moon, as it fits a bit more with Greco-Roman naming conventions than the Germanic "moon". But it's not as though anyone'll miss it. Also, why not just put all the moons in there? It wouldn't be any more impossible than some of the other recent quizzes.

	HollywoodLeo:	Oct 27th, 2008 at 05:59 GMT		17 points
	Pluto debate begins in 3..2..1...

	Antithesys:	Oct 27th, 2008 at 06:30 GMT		13 points
	To be fair to Pluto, it does have three moons and thus qualifies for this particular quiz. Then again, Eris and Haumea have moons too...

	micah:	Oct 27th, 2008 at 07:21 GMT		6 points
	Eris has at least one moon: Dysnomia. I don't know about Haumea. I agree that a more inclusive version of this quiz would be fun, although it'd probably have a completion percentage similar to the geological ages quiz.

	I can always remember the moons of Mars because of playing so much Doom as a kid. Glad to know that game came in handy for something.

	@faxman: Don't you understand? Playing violent videogames is supposed to turn you into a desensitized, maladjusted thug, not some kind of moons-of-Mars-knowing intellectual. Sheesh. Go do the Mortal Kombat quiz a hundred times or something.

	magister:	Oct 27th, 2008 at 17:25 GMT		5 points
	I agree with the more inclusive quiz. Especially since many of the moons of Saturn, and I think the moons of Neptune have stepped away from Greco-Roman.

	davidr:	Oct 27th, 2008 at 17:37 GMT		1 point
	@magister: The earliest-discovered moons of Saturn are named after the Titans of Greek mythology; later ones are named, in groups according to their characteristics, after characters from Norse, Inuit and Celtic mythology. Most of the moons of Neptune are named after watery figures from Greek and Roman mythology; however, the Uranian moons are named after characters from Shakespeare and from Pope's `The Rape of the Lock'.

	Faxman:	Oct 27th, 2008 at 19:15 GMT		12 points
	davidr - old video games are filled with great lessons. Doom can teach you about the moons of Mars, Castle Wolfenstein can teach you the history of the Third Reich, and Frogger can teach kids how to safely cross the street.

	Deadpool:	Oct 27th, 2008 at 19:22 GMT		3 points
	I agree with Antithesys. The first option I tried for Earth's was "Luna" since I was thinking of proper names and not just calling it a "moon".

	davidr:	Oct 27th, 2008 at 20:02 GMT		7 points
	But `Luna' isn't the proper name for the Moon in English! The proper name really is just `the Moon'. Sometimes, the things you learn aged five are true after all. :-)

	magister:	Oct 27th, 2008 at 20:34 GMT		5 points
	Okay. I wasn't sure of Neptune and didn't have the time to double check, it seems they find new moons every few months, so it wouldn't have surprised me to move away from Nereids, especially if they had brought in some Polynesian or Easter Island sea deities or something, similar to the new dwarf planets. Just for the record, and no disrespect, but that's where the "stepped away" came from. I didn't mention Uranus because I thought that was pretty self-explanatory, but thanks.

	magister:	Oct 27th, 2008 at 23:28 GMT		2 points
	Incidentally, davidr, I wasn't really careful when I wrote both of those posts. I wasn't as clear as I could have been on the first, and I wasn't as kind on the second. Thank you, that is important information that others may be interested to know. I will try to be more conscientious in the future. And avoid run-on sentences.

	davidr:	Oct 28th, 2008 at 00:46 GMT		-2 points
	No worries at all, magister! Well, except for the run-on sentence. ;-)

	Trying to think of whether anything should be added or removed from this, because it's kind of a hodge-podge. All the moons large enough to be rounded by their own gravity are here, which is good (and that includes Charon, even if Pluto isn't a planet! Charon's still an important moon.) But then there's Mars' moons, Hyperion, and Phoebe. I'm just saying I can't really see a consistent theme here... but I love the fact there's a quiz on this at all. :) And there definitely shouldn't be every moon. Nobody needs to list off the more than fifty Saturn and Jupiter each have. (Although maybe each planet might make a good quiz on its own... hmmm....)

	This gem of a quiz needs to be easier to find, say, by people looking for Science quizzes! :) Miscategorized?

	I think you'll find that Pluto was categorised as a dwarf planet. You do see the word planet at the end of that sentence?

	Joshbuckler:	Mar 15th, 2009 at 05:21 GMT		3 points
	If Pluto is included, then so should some other dwarf planets.

	omg_ponies:	Mar 19th, 2009 at 03:11 GMT		2 points
	Pluto does not have a satellite because the barycenter between Pluto and Charon is outside the surface of Pluto.

	Jono_:	Mar 19th, 2009 at 16:52 GMT		3 points
	why is there only one of Neptune's moons listed? Neptune has 13 moons. 10 are classified as major. The rest, besides Triton, may simply be space rocks, but they are classified as Major Moons.

	I typed in "moon" and then quickly refreshed the quiz to see whether luna would be accepted, very surprised to see that it's not...

	That's no moon. That's a space station.

	newenglander:	May 17th, 2009 at 19:56 GMT		-3 points
	luna should be accepable for our moon

	Pat423:	May 25th, 2009 at 01:22 GMT		3 points
	The real question is not why "Moon" is accepted. The real question is why, if it is accepted, 2.8% of quiz takers failed to get it correctly. That seems like more than the started-quiz-then-passed-out-at-computer segment. =P

	GeoExpert:	May 28th, 2009 at 00:31 GMT		1 point
	Phoebe and Hyperion are irregular moons and they probably should not be on this quiz. Note that there are over 200 moons in the solar system, but these are just the main ones. If Phoebe and Hyperion are on here, why no Himalaya and Thebe for Jupiter?

	GeoExpert:	May 28th, 2009 at 00:31 GMT		0 points
	Luna should be accepted, and so should be Moon

	Every person should know the Gaelilean Satellites. Io-Europa-Ganymede-Callisto

	GeoExpert:	May 28th, 2009 at 00:32 GMT		1 point
	Europa has an subsurface ocean!

	Jupiter has 63 known moons. Saturn has 59 known moons. Neptune has 13 and Uranus has 27. Mars has 2 and Earth has 1. Mercury and Venus do not have any. To the dwarf planets, Pluto actually has 3: Charon, Nix, and Hydra. Eris has 1 Moon, Dysmonia. Haumea has 2 unnamed moons

	GeoExpert:	May 28th, 2009 at 00:37 GMT		4 points
	On the Pluto debate: The Title of the quiz is "Solar System Moons" not "Planet's Moons." Therefore, dwarf planets can be in this quiz. Eris for Dysmonia should be included (Haumea moons and unnamed as of now and Ceres and Makemake don't have any)

	Wow, the three I got were the three most answered. I feel sad now. xD I knew more than just those three at one point, but I'm apparently having an off day.

	WHY IN THE WORLD DOES THIS QUIZ NOT HAVE VERY MANY PLAYS!? It has the potential to be the most-played Sporcle Science quiz, and it only has 15,000!

	AjC:	Jul 30th, 2009 at 14:54 GMT		-2 points
	I don't think they should bother adding all the extra moons as official answers, but they should be available as bonus answers, like the countries of the EU quiz. Another bonus answer should be Earth's "2nd moon" (actually a quasi-satellite)known as Cruithne (pronounced "k-rin-ya").
