Only missed Makemake, but that is because I could only come up with 90377 Sedna (or just Sedna). When I looked it up, it said it was 3x10^21 kg. When I looked up Makemake, it said the mass was 4x10^21 kg. You should probably make Sedna an accepted answer, or better yet, your quiz seems to be a little off based on a list I found. http://www.suberic.net/~dmm/graphics/astro/size.html I think it's just a couple of the last 5 or so that are different. Also, Luna should be accepted for Moon.

Weighing the planets in kilograms is a novel approach. Does that mean that Jupiter gets bonus weight since it's own gravitational field is stronger than Earth's? And I never would have guessed that a big ball of fire would have any weight at all.

Indeed, it should read "Mass" instead of "Weight".

Something has to be on fire for there to be a big ball of fire. Fuel has weight. Hydrogen might not weigh very much in small amounts but try putting a few trillion cubic meters of it in a can and weighing it in a vacuum...

Apr 10, 2016

I don't think you get the point. Weight is a force, an expression of gravity for objects bound to a celestial body. It is proportional to mass but it is not mass itself... an usual and understandable confusion, but still a mistake.
delete
Apr 11, 2016
(69)
I know what weight is. I took high school Physics (and college Physics). If Jerry is trying to make the point that you are, then he articulated it very poorly. A giant ball of fire definitely has weight. And mass. These terms are often used interchangeably in layman's parlance.

It's also not a novel approach at all to measure celestial bodies' mass (weight) in kilograms.
delete
Apr 13, 2016
(72)
I'm not quite sure, but I think he was trying to be witty about that, yes. Anyway, weight (a force) is not measured in kilograms but in newtons, so there is a mistake.

Don't worry, it will keep getting more and more massive. At the same time it has to be contained within Donald Trump's body. That's why eventually the ego gets so dense it collapses into a black hole and gobbles up all of Earth. Then it will easily make it into this quiz.

Aren't there many objects similar in size to Pluto in approximately the same orbit or a little further distant? So many in fact that they typically just have boring letter/number designations instead of proper names? And this is one of the reasons that Pluto was given a new designation "dwarf planet" since keeping it as a planet would require classifying these other objects as such?
reply

Apr 10, 2016
(55)
The objects you may be referring to are Kuiper Belt objects, which are typically further from the sun than Pluto on average, and which typically have highly elliptical orbits. Some of them have orbits with a perihelion (closest approach to the sun) fall within the orbit of Pluto. At least one of the KBO's, Eris, is about the size of Pluto, and it's just a matter of time before more are found that are of similar size, or possibly even much bigger. (I think I got that all pretty much right.)

Eris, Haumea and Makemake in this quiz are of that group; Sedna and Quaoar are others that did not make the cut.
