Given recent discoveries suggesting that life might after all be possible elsewhere in the Solar System, and Hodgkin's Law of Parallel Planetary Development, it seems a little presumptuous automatically to assume that Earth contains the most KFC outlets

It's a little tricky to determine when, exactly, quicksilver started being called "Mercury" as it kind of backed into that name, but it seemed to definitely happen before 1798, when Tellurium was named after the earth. But even there, the bases are covered, as Tellurium is a metalloid, not a metal.

Level 81
May 21, 2023
I put Jupiter for this, and Jupiter likely has more water than Earth by far, but there does not seem to be a consensus exactly how much.

Uranus and Neptune almost certainly contain far more water than Earth, maybe as much as Earth's total planetary mass.

There are also several large moons that contain more water than Earth.

It's a pretty fraught question and astronomers don't seem to have a good answer yet, but it's almost certainly not Earth.

Technically speaking, since axial obliquity is measured from a counterclockwise perspective, Venus, with a tilt of 3° off from its axis but also with a clockwise rotation, has an axial obliquity of 177°, and is therefore the most axially tilted planet.
+2
Level 85
May 20, 2023
Wikipedia has it that "There are two standard methods of specifying a planet's tilt. One way is based on the planet's north pole, defined in relation to the direction of Earth's north pole, and the other way is based on the planet's positive pole, defined by the right-hand rule." I'm using the first method, which I'd say is the more intuitive for the layperson and so better for a quiz like this.
+2
Level 70
May 22, 2023
I put Venus based on the second method. Maybe you could specify this, for example by saying "axial tilt is a number between 0 degrees and 90 degrees". To me it is not obvious that one method is more intuitive than the other, it just depends whether you want to think of planets like Venus and Uranus as rotating backwards or as tilted by more than 90 degrees.
+3
Level 85
May 22, 2023
That's too wordy for a specification, but I've added the specific degree of tilt in brackets (82.23°) which should suffice. That couldn't possibly be Venus.

I meant intuitive in that Uranus is known to "roll like a ball" as opposed to "spinning like a top", as with the other planets (Venus especially!). To be fair though, Venus is known to "spin backwards", so I take your point.

Dang, I was really thinking the metal question was a trick, and that mercury was named after the god, but nope! Dang alchemists.

The planet is named after the god. The question is about the metal being named after the planet, not vice-versa.

Jun 17, 2023
Yes, I know. That's what I'm saying. I thought that mercury (metal) was named after Mercury (god), but I was wrong. I was blaming the alchemists because they were the ones who named mercury (metal) after Mercury (planet).

Doesn't Mercury tend to reach higher temperatures than Venus?
+2
Level 85
May 22, 2023
From NASA: "Even though Mercury is closer to the Sun, Venus is the hottest planet in our solar system. Its thick atmosphere is full of the greenhouse gas carbon dioxide, and it has clouds of sulfuric acid. The atmosphere traps heat, making it feel like a furnace on the surface. It's so hot on Venus, the metal lead would melt."

"Instead of an atmosphere, Mercury possesses a thin exosphere made up of atoms blasted off the surface by the solar wind and striking meteoroids. Mercury's exosphere is composed mostly of oxygen, sodium, hydrogen, helium, and potassium."

Never mind just realized they have one question. Still kind of depressing though, every other planet got multiple questions
+2
Level 85
May 23, 2023
The first version of the quiz had 3 answers for every planet, but I deleted the four that had very low correct guess percentages. Uranus also was the answer for:

Planet that reaches the coldest temperatures. (Everyone presumes Neptune, but because of Uranus being tilted on its side it has a dark side which never sees the sun and is very cold!)

First planet discovered with the use of a telescope. (I really liked this question, but not many could guess it.)

+1
Level 67
Sep 19, 2023
You could have said "discovered with telescope rather than naked eye" which would eliminate Jupiter and Saturn, and of course, since Uranus is bigger and closer to Earth than Neptune (most of the time), it would be the obvious answer I guess.
+2
Level 67
Sep 19, 2023
Also, what were the other 2?
+2
Level 85
Sep 20, 2023
“Rather than the naked eye” is implicit in “discovered by telescope”. If you can just look up and see it then you obviously don’t need a telescope to discover it. As I say, guesses were low. People don’t necessarily know which planets can be seen with the naked eye or not.

I can’t remember the other two.

+1
Level 72
Mar 29, 2024
I would keep the telescope question in. Maybe word it as planet closest to the sun which isn't possible to see with the naked eye. Or something. Then they don't need to be aware of the discovery. (though imo it is a fact that pops up now and then, as for the axis, I personally never come across that, and the size of the gasplanets I most likely have, but does not register as it is not an interesting fact (as opposed to a new discovery) but again, that is my opinion)

He thought about it! A bit late now that this has been featured, but it would also require changing too many questions. Kind of obvious if you can see them which one is the red planet, or the one that looks like Earth's moon, or has a red spot, or the most rings...!

The planet-with-the-highest-temperature question is a bit dodgy: Venus certainly has the highest surface temperature of all rocky planets. But there are higher temperatures in the core of each planet. And for gaseous planets, it's not clear where the surface begins, so you should allow for temperatures anywhere in the planet, including the core. I would guess, Jupiter would be hottest then, but I'm not sure.
