Are these common in the asteroid belt or as smaller moons of the outer planets?
"The team says that the two spheres likely joined as early as 99 percent of the way back to the formation of the solar system, colliding no faster than two cars in a fender-bender." Welded together by gravity, i'm really in awe seeing the, by far, weakest power so lovely at work.
So, two masses were close enough in relative velocity and vector, that one of them didn't careen off the other one, and instead, allowed the weakest of all known forces to bond them together as they hurtled at high velocity through space. This object(s) seem statistically unlikely to me. I'm not saying it's artificial. That would be even more unlikely, by orders of magnitude. Just saying "Wow!".

I personally find it amusing and interesting that the physical object, Ultima Thule, looks similar to the Virtual Game logo "Ultima" https://upload.wikimedia.org/wikipedia/en/6/6a/Ultima_Online...
I find it truly amazing that New Horizons was able to take photos of a 20 mile object whilst flying past at ~8 miles/sec - that’s an incredibly small space and time window within which to capture the images. Does anyone know how NASA manages to pilot spacecraft with this level of precision? What kind of engineering processes do you need to enable this?
The book Digital Apollo touches on a wide range of issues associated with building systems that can do this.

As this is the first Kuiper Belt Object we've visited, it's hard to draw much about the statistics of the thing.
