Does this crater, presumably, have a high albedo?

18: You're presuming that it is a crater? Well, I'm not aware that it has a high albedo ... in fact I would make an educated guess that its albedo is quite low...


Well, it is ... but there is more than one way to make an impact.

I was afraid of that... Dang, had I only been more specific.

It looks quite gloomy for us; on the other hand, even a question like "Which Lunar feature am I thinking of?" might have been worth 20 questions... got a little extension for us, Eroica ?

Anyway

19. Is it a central mountain, crater/basin rim, basin ring, or part of any of these?

(These are the other impact features I can think of; the "other way" to make an impact :blush: )

OK. Since Dave realized it was a lunar feature after 12 questions, I'll extend the game to 32 Questions!

19: No, it's none of those.

Hint #1: it's an impact feature in the sense that it's a vestige of an event in the past that made an impact in more than one way...

Hint #2: some people are going to be slightly miffed at me when they hear the answer!

Is it an impact caused by an Apollo event, such as a shoe print? [We haven't asked 20 questions yet, and then we get to guess the answer.]

Well done, George! (So much for the extension.)

Reading between the lines, I think I can interpret your 20th Question as:

Is it Neil Armstrong's famous first footprint on the Moon?

And that is exactly what I was thinking about. I hope the board accepts this as a genuinely astronomical object.

That was brilliant, George. As soon as I saw your response, I knew it had to be correct.

We all seem to just squeak by at the last question.

Let's try another 20...

What in the universe am I thinking about?

Is it larger than a cubic ly?

2) Nope. It is smaller than an astronomical bread box.

Is nuke-you-lahr fusion happening there?

Dang it again! Let me regress and correct my error. [My mind was on another object (non spherical) I have been wanting to use, sorry.] Your question would not likely be asked, though no. 5 is a logical question.

5) It is not in the Solar System.
4) Spherical it is.
3) Fussion is not happening there.
2) Nope. It is smaller than an astronomical bread box.
1) Yep. It is in our galaxy.made an error, already.

Is it a compact object (denser than the core of an actively fusing star)?
