So, we had this homecoming event with a “space” theme. Since I have a show on the university radio station, they asked if I would participate in the event and ask students space trivia questions (for candy). Of course I would.

Since I had to come up with questions, I figured I should share them. There were some that didn’t work so well, I will include those at the end. I’m going to include short answers to these questions, but it’s going to be difficult since I love talking about science.

Let’s get to it.

Name a planet that has a name related to a day of the week.

Answer: You can pick one of the following: Mercury (Wednesday), Venus (Friday), Mars (Tuesday), Jupiter (Thursday), Saturn (Saturday). Here’s a more detailed explanation of these days-planets names.

This was a fun question. Most students came up with the answer Saturn — that’s the obvious one. But it wasn’t impossible.

Name a planet that does NOT have a name related to a day of the week.

Answer: Yes, this is basically the same as the previous question, but I didn’t ask students both of these questions. The planets that would work for this question are Earth, Neptune, Uranus, Pluto (you can have an argument about Pluto if you like). Also acceptable would be any…
