For anyone passionate about orbital dynamics: IMO it would be great to get more eyes on and thorough critiques of the Tychos model put forth at https://www.tychos.space where there is a book, visual simulator, forum, etc.
The sincere claim put forth appears to be that Tycho Brahe was almost right, and that something like this is in fact true:
- The planets except for the Earth orbit around the Sun
- The Sun orbits around the Earth
- The Earth has its own small orbit
It is pretty dense information, but seems important if true. I believe that the Tychos model is claimed to be just as consistent with observation as the conventional model, if not more so (with some arguments in the favor of the Tychos model as more likely, which escape me).
An excerpt from the abstract is below, listing some issues they have with the mainstream heliocentric model, which are presumably resolved elegantly by the Tychos model:
Anomalies of the Keplerian/heliocentric model include:
1: whether the Sun has a binary companion,
2: why only Mercury and Venus have no moons,
3: why Venus always presents the same face to Earth at its closest approach,
4: the “anomalous” precession of Mercury’s perihelion, and other aspects of Mercury and Venus,
5: the cause of the General Precession (Newton’s lunisolar wobble theory is not it, it does not match with observables),
6: why Mars and Sun exhibit 79-year cycles locked at a 2:1 ratio (and many other “harmonies” found between bodies),
7: why there is a sidereal diurnal variation of G, in interferometry results, and in the movements of stars,
8: why sunspot formation location shows a geocentric preference, and more.
