Heavenly Bodies to use for Extraterrestial Astrology

What planets and moons should be used for an astrological chart cast from elsewhere in our solar system? This is an attempt to answer that.

For each body, I've assumed that moons of other planets are not visible or at least never get sufficiently far from their planet to be significant. However, some of the other planets may not get very far from the Sun, and if the subject of the chart is on a moon, other moons of that planet may not get far from the planet.

The chart below shows the angle range of the eligible bodies around the object they're orbiting. To simplify the math, I'm pretending that all orbits are circular - this is false but not wildly so, except for Pluto and Nereid, and I don't think it affects the results for Pluto. If you need to cast a chart on Nereid, you may want to do further research.

Red entries in the chart indicate a range of less than 20°. Such bodies are always within 10° of their parent and thus always in conjunction. Orange entries have a range of less than 30° and are never more than 15° from their parent. A body with a range of 28.8° would spend half of its time in conjunction. Yellow entries have a range of less than 40° and are never more than 20° from their parent. They're in conjunction with their parent at least 1/3 of the time.

I think the red and orange bodies should not be used, as they are too close their parent bodies. The yellow bodies may or may not be distant enough. The Extraterrestrial Astrology article suggests using 10 bodies for every chart - yellow bodies may act as a "fudge factor" to make reaching that mark easier. For locations like Nereid and Hydra with few available bodies, outer TNOs such as Sedna and Quaoar may be used. For locations like Saturn and its inner moons with many bodies, some of the outer planets and moons may be removed.
