Thanks JD I shall add these!  Is the Moon within a Moon thing a real object also?  And what about UltimaThule? I have heard that one mentioned previously.


Jack Dole is to SE mods what Isaac Asimov was to science fiction- the most prolific and best by a long shot and it's not even close!

I made a little bug fix in the script.

Nice addon, maybe the two lobes of 2014 MU69 should be red in color and its north rotational axis should be facing toward the Sun.
Also, you put the diameter estimate of each lobe as the radius which made 2014 MU69 twice its actual size.

This is unfortunately a mistake that sometimes happens to me.

For this, the axis of rotation of the Barycenter would have to point to the sun. (As far as I know.) This does not work in SE 0.980. (In SE 0.990 it works (currently)).
In SE 0.980 I have to do a trick for it. I have to replace the barycenter with another asteroid. (A very small, with a radius of 1 meter.)
Then it works.
(However, the South Pole of the axis must point to the Sun for Ultima Thule to rotate clockwise, as in this video: https://www.youtube.com/watch?v=kSHOOFBxRvA )

I appreciate the update, I'd like to let you know that you could change the orbital inclination and the ascending node of the lobe orbits around the barycenter.

If someday I get more accurate rotation data, I will update the system.

Would a similar trick need to be done for contact binary *stars* in SE 0.980?

Not that I know.
If you mean something like this, these are just 'thin' suns.

JD, do you think the UltimaThule V0.2 version is the final version of that add on or will you be updating it? I downloaded it and was thinking of adding it but wanted to wait to see if you were working on an update? And is the V0.2 version the only file that should be added and not the other UltimaThule.sc files uploaded before that?

Only the most recently posted file.

But that can still take a while.

Okay I will add the 0.2 file then, I like the object it looks like a snowman floating in space haha

There are some features on Ultima Thule that could be either albedo variations or big chunky craters, but we can't tell until New Horizons transmits higher resolution photos. If they're big craters, the script will need a lower craterFreq and a higher craterMagn.

I have a request! Is it possible for a planet to be trapped in the middle of 2 stars?
