I am trying to create a graphic with the sun, moon, and earth in the same frame as if looking from the end of the Apex node, assuming a 100,000 km tether, but with the correct sizes, placement, axis angle and color. Something like this.....
This graphic has issues....
1) It is not from the point of view of the Apex node at 100,000.
2) I have no idea if there is ever a time in the orbits of the earth, moon and sun where they would close enough to preserve the scale.
3) I have no idea if the colors are correct.
4) In the real world the tether would loose visibility quickly as it get farther away from the view point. But how soon? 100km out?
5) It is not to scale.
Question 1) Where would a non-expert go to get answers?
Question 2) Is there software that can do this?
