comment Why planet's orbit is not perpendicular or random ?
Typical deflection time does not mean that all deflections take place at that moment. There are deflections way before that. Think in typical height for men in your country. Are there men higher than that? And shorter?

comment Motion of the sun as observed from mercury
The combination of two movements, one "horizontal" with forward and backward and one "vertical" caused by the inclination of the Axis, the same one we experience on Earth where Sun is higher in sky in summer and lower in winter.

comment Why planet's orbit is not perpendicular or random ?
Elliptical galaxies are dwarf galaxies, sort of giant globullar clusters, so they have had the same processes as globullar clusters, including huge amounts of interactions and ejections. Each star, indeed, keeps its own Angular Momentum, and the system as a whole (elliptical galaxy plus ejected stars) does as well, but the galaxy not counting the ejections, which is the observable body, does not.

The intercation among stars on galaxies is very tiny. Globular clusters have a density of 10^5 to 10^6 stars in a very small sphere (on the magnitude of 1pc, almost never reaching 10pc), while galaxies have a density of 10^11 or 10^12 stars in an enormous disk (on the magnitude of 10^4 or 10^5pc)

comment Why planet's orbit is not perpendicular or random ?
The orbits of stars on a globullar cluster are seemingly random due to the enormous amount of interactions they have had among the stars, including ejections of some individuals that effectively change the angular momentum of the cluster.

Question is not clear. Do you want spherical triangle formulas? Or real space ones?

Which phenomenon in particular? I think the animation you linked was quite correct and cool.
