This is not correct at all. Observe from any planet you like in our solar
system. Then the planets superior (farther from the sun) to that would
have oppositions and solar conjunctions and retrograde loops, just like
superior planets exhibit from Earth, predictable motions. Planets inferior
to your observing location would go through the cycles of morning appearance/
superior conjunction/evening appearance/inferior conjunction (assuming your
planet isn't rotating retrograde, in which case reverse morning and evening).
Again, exactly the same as what you see of Mercury and Venus from Earth.

Again, this argument (the one I think you're making) is false. The saem
thing can be seen from any planet.

The center of mass of the Earth/Sun system is well inside the Sun, so in
that sense the heliocentric system is more real. But of course, the SUn
is whipping around the galaxy and the galaxy moving relative to others.
