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.

The element Mercury has been named after the god, the other ones (Uranium, Neptunium, Plutonium) after the planets.

From Mercury’s wiki page under etymology:

The modern English name mercury comes from the planet Mercury. In medieval alchemy, the seven known metals—quicksilver, gold, silver, copper, iron, tin, and lead—were associated with the seven classical planets (Mercury, the sun, moon, Venus, Mars, Jupiter, and Saturn respectively). Quicksilver was associated with the fastest planet, which had been named after the Roman god Mercury, who was associated with speed and mobility. The astrological symbol for the planet became one of the alchemical symbols for the metal, and Mercury became an alternative name for the metal. Mercury is the only metal for which the alchemical planetary name survives, as it was decided it was preferable to quicksilver as a chemical name.

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.
overtired

Level 88
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.
TWM03

Level 72
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.
overtired

Level 88
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.

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."

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.)

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.

“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.

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.

I was coming here to leave the same comment.

Seems like the distinction between ice giants (Uranus, Neptune) and gas giants (Jupiter, Saturn) has been made by astronomers since the '70s, but the term gas planet is colloquial and applies to all four. So I guess the quiz is correct enough.

As a professional scientist who studies Saturn's rings, I can tell you that this is incorrect. Saturn's main ring system is mostly a continuous disk, not thousands of individually definable rings.

It would be better to add the word "substantial" so that the question asks which planet has "the most substantial rings."
