Altair and Vega are exactly 15.00 light years apart !!! (no replies)

workin on the 3D Starmap
n ok ...not for nothin, but...
connecting lines between stars
as in a constellation otherwise,
the very local / very bright stars
Sirius, Altair, and Vega
are about 9, 18 and 27
light years away
respectively...
for one thing...
so: 1a, 2a and 3a
...if we say a = 9...

but also, now...
the line between
Altair and Vega...
they're exactly 15.00 light years apart
and the connecting line between them
is inclined exactly at exact degrees
relative to Earth's north-south pole
360 equal wedges of a circle
which is a human invention
OMG 17.5° and 20.0°
which is 7b and 8b
if we say b = 2.5

...the blue orb is Vega...
or rather, the Vega system
0.2 light years in diameter
(or about 5% the distance from us
to the nearest star Alpha Centauri
- or about same as our Oort cloud)

...the cylinder connecting is
0.03 light years in diameter
2000 AU, Earth-Sun distances
(pale Blue on the lower right)
...you can see inside the orb
this new line touches center
as closely as all the others
...right in the exact center
the heart of the solar system
where any planets would be
and same for the other star

the Origin and Position numbers
are just the average coordinates
(xyz positions for the two stars)
the center point between them
relative to our position (0,0,0)
