Nope, I just did that in the testing phases to make sure my interpretation and
implementation of the 6 orbital elements wasn't WAY off.
Still working on that "Mean anomaly at the epoch" part.
I'm guessing that's it's position at some well-defined time-point.

I'd thought of something like that - maybe a RAM disk, a SSD, or a USB3 stick.
The parsing takes longer than the data reading.
The number of spheres isn't TOO bad - considering my rgb histogram analysis
processes millions of them for certain images. (it just takes forever)

Be sure to take your frog pills today.
And wipe your chin.

I think that there is. Likely even Google has some of it.
I need to figure out how to reject badly-formed data, like the E's, the MPE's,
the MPO's, etc in the data set, so I don't have to manually delete them.
I also need to figure out how to plot the objects that look like they have
parabolic paths. I haven't yet reasoned that out or investigated the equations
and parameters for those yet.
I can't imagine that there are things with hyperbolic orbits - but the universe
is a surprising place.
So, I have the planets, a lot of the moons, and asteroids.
UV mapping of the planets and moons.
(BTW, I really like the way your Earth looks with the normal mapping - I haven't
gotten that far yet)
A realistic starfield in the background would be nice - esp if there were some
actual constellations in approx the right place. That would make a very nice
sky_sphere indeed.
Not sure what else to throw in there - galaxies, nebulae - not sure what's large
enough to be seen (if I fudge the scaling like I do with the planets and
moons...)
Comets would be very cool, and some of the man-made-satellite models as well.
Also on the list is a nice fly-through path for the camera to travel through the
solar system and pause around each planetary system for a bit.
I suppose each data set for each set of objects could be worked out, and
included in the central scene file. Things like the asteroids could be limited
with a bailout number - which I already have implemented.
..... and if things get too unwieldly, we can always have Dick Balaska do all the
animation frames on his render farm ;) :D
