Ingo is factual and humorous, so
- it closely orbits the Sun
- it is large, round, maybe the size of a planet, and under gravity
also,
- we can't see it
There are only so many words beginning with M and S,
missing, spaceship, ...
and the number 15 ...

::shaking head::

I'll give you a huge clue. You might think it's silly but other than this, I'm not expanding. It's not at all as serious as many might like to believe. Do a little searching on some of Ingo's "peers," professional or otherwise. Namely, Poul Anderson.

If you can't connect the dots as to why Ingo Swann was curious what was there... well.

If you want, you might also with to ask Don Ecker. He might shed a little light.
Years later and people still asking about this.

No, actually the Poul I am referring to was an author that was publishing works around the time that Ingo was around doing his thing, maybe just slightly prior. Ideas were put out there that increased interest in "I wonder what's out there on the other side of this, this, and this... popularized in certain media.

This is conjecture among a select group but seems to add up considering the concerns with "hidden" things, as well as anything that might be used during warfare. MS15 is was a just a public code. Later, when Ingo became involved in "researching" more information regarding the type of work he was being asked to do, he found some people's work more influential than others.

But again, to hear it from someone (who may be the last individual who truly "knows"), contact Don. He held a number of interviews on things like this.

Well, no one posted a response so I guess I can throw this out there then.

An asteroid exists named 2010 MS15. The question is whether or not this could be classified as a Potentially Hazardous Asteroid (PHA). But it is not watched or tracked but perhaps once a year, if even, at this point in time. Its minimum orbit intersection distance (MOID) is 2.3193 AU. Objects with an AU less than .05 are considered PHA.

Poul Anderson was a writer that Ingo was purportedly interested in regarding his works about space and even thermonuclear weapons. At that time, this was a major concern. So people started wondering about things they thought existed on "the other side" and so it went on. He looked at the other side of the moon, and then the other side of the sun.

Putting 2 and 2 together, it's safe to say that his drawing was a representation of another celestial body that apparently concerned him enough to put out there for others to investigate.

You will not find the above info anywhere on the net, other than in regards to technical info on the asteroid. I say this because at this point, you're free to believe what I'm telling you, or not.

I mean this respectfully, btw:

Try using a non-digital type of camera. You get those little black dots in the sun or light sources when the electronic chip inside is overloaded. I can't recall what this this called in the photography world... look into it though if you have the time. No black hole though, thankfully... =)
