TRAPPIST-1, an M8V "star" is supposed to have 7 planets... until you correct for the scaling errors in modern astronomy, then you find they discovered 7 moons around a red, gas giant planet about 80% the size of Uranus. (Unfortunately, we do not have a "red" gas giant for comparison, but Uranus comes very close.)

Correcting the scaling error, you find the Trappist-1 "planets" have nearly identical orbital characteristics with: Miranda (b), Ariel (c), Umbriel (d), Titania (f) and Oberon (g), the periods being off by about 5% for b, c, d and f, and 9% for g.

All of these 7 moons are approximately 75% the size of our own moon.

moon: period(d) / Diameter(km) / Semi-major Axis(km)
b: 1.51/1384/166203 → Miranda: 1.41/471.6/129390
c: 2.42/1346/227688 → Ariel: 2.52/1353/191020
d: 4.05/984/314156 → Umbriel: 4.14/1169/266300
e: 6.1/1170/418874
f: 9.2/1332/553512 → Titania: 8.7/1577/435910
g: 12.35/1436/673190 → Oberon: 13.46/1523/583520
h: 20/962/942467

Since Trappist-1 is smaller than Uranus, the semi-major axis measurements are off by almost exactly 20% (0.78, 0.84, 0.85, 0.79, 0.87) for all the comparisons. That would make the "star," itself, have a diameter of 20447 km, or about 3.2x the size of the Earth.

That's no moon, it's a spac.... no... wait, you're correct, they are moons! :lol:

It's an interesting correlation looking at these "new" moons and the moons of the gas giants in our own solar system, especially the 20% difference in axis measurements and equal size reduction across the board. Either all moons follow a set pattern and have similarities as solar systems do (rocky moon, ice moon, cratered moon, ringed moon, geologically active moons, atmospheric moons etc.), or those making this discovery just used our own ones as templates for the diagrams, or both!

Speaking of moons, would you say that the hypothetical moons such as Chiron and Themis were actually sightings of the LM Great Ark?

Lunar and planetary orbits actually follow standing resonance patterns. This was noticed centuries ago and is documented in the Trivium / Quadrivium. And they are "discrete" waves, since they can all be described by inscribed/circumscribed polygons. So all the orbits end up following harmonic sequences... what we call "mass" is just the "key" that gravity is playing in.

Most likely, since that "moon" of Saturn seems to come and go as it pleases (like Vulcan, inside the orbit of Mercury).
