I mean, so is the Sinai peninsula but it does say that the map is not drawn to scale. So I just assumed that those pieces of land are very very small in the map and thus unable to be seen at the distance pictured. Quiz maker's prerogative.

Saturn, Uranus, Neptune, and Pluto are given away by the "Type" column (and, to a lesser extent, Earth and Jupiter). You might just as well give the planets and make it the largest objects other than planets.

This quiz isn't meant to be especially difficult. I'm making the assumption that people who don't know the planets probably aren't going to get it from that column, but even if they do I don't think it's that bad. The planets don't seem to be the competitive part, given that all of them are typed in by ~98% of the quiz takers, but there are plenty of other more challenging answers that fewer people get. Thank you for the suggestion.

QuantumMechanist

Apr 21, 2021
Haha yeah this one made me laugh too. Gonggong is a water god in Chinese mythology. The International Astronomical Union's criteria for naming objects like Gonggong is that is must be named after a mythological figure pertaining to creation. Gonggong happened to be associated with water, ice, and the color red, which fit all the criteria. For a time after discovery before it was found to be red and when it just had a numerical name, its nickname was Snow White.

When you talk things that are "in" the Solar System, you're thinking of things that are gravitationally bound by the Sun (Sol). The Sun is more than "in" the Solar System, it kind of is the Solar System, in that there is no Solar System without Sol.

Why are Haumea and Makemake listed as "Dwarf planet?" with a question mark? Haumea was declared a dwarf planet by the IAU on September 17, 2008, and Makemake was declared a dwarf planet on July 11, 2008.

Hi,

Dwarf planet designation is in a weird place where several bodies are stuck being called a dwarf planet by one group of people and something else by another group, so I had a hard time figuring out the specifics.

It looks like you're right though, so I'll have that fixed.
