	Nice quiz!

	Nice quiz, but could you capitalize the answers, as they are planets. Thanks!

	Talk about a guessing game. But maybe that's because I don't know my Mars from Uranus.

	PumpkinBomb: Actually, your weight on a given planet goes like its density times its radius, or its mass divided by the square of its radius. Either way, size does matter. ;-)

	Since quizzes cannot be shorter than one minute, how about increasing the difficulty by penalizing wrong answers? It's trivial to simply guess each answer.

	I still haven't adjusted to this whole Pluto thing.

	@PumpkinBomb and others: Density actually does a horrible job of describing it. For example, Earth (the densest) is over 4 times denser than Jupiter and over 8 times denser than Saturn (the least dense), but that obviously is far different than this list. TimeAndTide's explanation is the only accurate one.

	Yeah I missed the top one on the 2nd column as well.

	biskit67:	Dec 13th, 2009 at 13:12 GMT	7 points
	Earth was actually the first one I got. lol The rest of them were basically how fast can you type and re-type the planet names. I did have some clue it would probably be based on planet size.

	Secret_Asian_Man:	Dec 13th, 2009 at 13:44 GMT	9 points
	Yes the force due to gravity is proportional to the mass divided by the radius squared. Uranus's mass is 4x that of the earth and its radius is 14.5x that of the earth, so the gravity turns out to be about 90% of that on earth.

	biskit67: I actually did almost the same thing, except with only guessing random planet names without a clue

	Pluto for life! You'll always be a planet for me.

	Bojan:	Dec 13th, 2009 at 16:01 GMT	3 points
	I am surprised Jupiter is among hardly guessed ones since it is well known that it is the biggest.

	trumpetchic94:	Dec 13th, 2009 at 16:11 GMT	2 points
	i epically failed. but hey, i got earth and jupiter!

	SOOOOOOOO many bad puns-I love it!

	rlnintendo:	Dec 13th, 2009 at 16:18 GMT	4 points
	i got them all on my first guess for each. I don't even know how thats possible. Yes, i agree with nucleolus101... love all the puns.

	performax:	Dec 13th, 2009 at 17:09 GMT	9 points
	Just a few decades ago, the order would have been quite different. That was before measurement of planet density was better established and in particular it was not known that Jupiter, Saturn, Uranus and Neptune were giant "gas bags." Though I don't remember the exact weights, it was thought that a 160 pound person on Jupiter and Saturn would weigh many times their weight on earth.

	stevo88ncfc:	Dec 13th, 2009 at 17:10 GMT	5 points
	Your mass doesn't change only your weight does. Your weight is your mass (m) X acceleration due to gravity (g) and each planet has a different value of g. g is proportional to the mass of the planet and inversely proportional to its radius squared. So generally the bigger the planet the greater your weight

	pbrown:	Dec 13th, 2009 at 17:14 GMT	9 points
	Suprising, earth is not the most guessed answer. Heck, not even 80% get it!

	It's amazing the amount of sympathy a large lump of rock millions of miles away can get.
