Another remarkable feature is the brightening of comets as they approach the central Sun with perhaps the brightening around the 21st January being the best of that year.

Identifying comets on a celestial sphere is perhaps enjoyable in its own way and seems to have a large following, however, to see the inner solar system and all the dynamics going on is far more satisfying for those who can make the adjustment.

Again, low hanging fruit for the first people to make correct judgments from orbital perspectives minus daily rotational effects.

Nothing could highlight your inability to visualise more than than your
belief that comets brightening as they approach the sun is “remarkable”.

If you had any interest in comets you would be out with a pair of
binoculars observing them with and without magnification rather than
staring at YouTube images or googling information about a comet you never
saw from a decade ago.

My ability has been to partition direct/retrograde motions by perspective based on slower moving planets in wider orbital circumferences from faster moving planets in smaller orbital circumferences. With human

What was missing was timelapse I needed to present the inner solar system as it actually appears from a moving Earth where the stars move from left to right and parallel to the orbital plane -

Maybe you want to shoot yourself in the head on account of an eccentric British individual who manufactured a resolution for direct/retrograde motion at variance with even the original Copernican insight based on relative motions between the Earth and slower moving planets with a Sun centred system inferred from the resolution of the illusory direct/retrograde loops.

The back and forth motion of the inner planets ( direct/retrograde motions) are there before everyone based on the ability of a satellite to create a permanent solar eclipse like conditions. This insight is here to stay so let all the barking dogs have their day.

Of course, that ability is more theoretical than real.

For one thing, L1 is not stable, so the satellite would need a supply of
propellant.

For another, the earth-sun L1 point is about a million miles from the Earth, so
the satellite would only have to have four times the diameter of the Moon.

Of course, that _is_ irrelevant to the fact that the apparent motions of Venus
and Mercury show they orbit the Sun in much the same way as the apparent motions
of the Galilean satellites show they orbit Jupiter. That indeed is an insight
that is here to stay; I'd also like to say that it never went anywhere in the
first place since Copernicus, but given the reaction to your expression of that
insight, I'm beginning to wonder.

Now, now. We all should know that he looks upon _that_ sort of interest in
comets with contempt as a mere "magnification exercise". Instead, he is
interested in comets for the truth they can reveal.

He did not, though, elaborate on how comets confirm his idiosyncratic view of
the Solar System. But it could simply be that he agrees with you, in his own
way, that it is expected that comets will brighten in a Copernican solar system
from getting closer to the Sun - thus, it's a remarkable proof that Ptolemy was
wrong, and he sometimes seems to be laboring under the delusion that
professional astronomers these days are covert Ptolemaicists.

At least you have enough dignity left not to entertain the nuisance but what is puzzling is that you were the first to affirm in this newsgroup the proof of the Earth's orbital motion as the stars change their position parallel to the orbital plane as the Earth travels in its circuit -

https://sohowww.nascom.nasa.gov/data...current_c3.gif

As Mercury moves out of the range of the camera, what is left is the procession of stars parallel to the Earth's orbital plane and the central Sun making the celestial sphere system worthless until it is assigned its rightful place as a useful framework for spotting objects, predicting events using dates and clocks or engineering concerns. What can't be done is modeling or justifying our planet's motions based on RA/Dec or the 'clockwork solar system' as it became known via the wishful thinking of experimentalists/theorists.

It took the British over 150 years to accept the crucial calendar correction the Church instituted in 1582 which brought dates in line with the actual position of the Earth in respect to the Sun but the signs are that the wider community will adopt the perspectives of the faster moving planets fairly quickly and it is delightful.

The point of this thread is that there is so much going on with the inner solar system when the Sun's glare is negated and even the planets moving in the background when otherwise it is obscured by the Sun's radiation (daylight). It is all remarkable for those who haven't lost the adventurous and curious nature that was present when we were younger but was beaten out of us by an education system who made the whole thing the preserve of voodoo merchants, bluffers and people who imagine they are astronomers through magnification alone.

I see nothing advantageous with observing the prograde/retrograde motion of the inner planets as opposed to observing the same motions of the outer planets - except that they occur more frequently for the inner planets.

How cute !, a newbie in this newsgroup is as rare as a supernova. The general run of things is that newbies don't hang around but others come and go while exercising their higher reasoning which comes with this type of astronomy.

To be fair to you, the original Sun-centred astronomers thought that the faster moving Venus and Mercury also demonstrated illusory loops like the slower moving planets and their wider circumferences -

"Now what is said here of Jupiter is to be understood of Saturn and Mars also. In Saturn these retrogressions are somewhat more frequent than in Jupiter, because its motion is slower than Jupiter's, so that the Earth overtakes it in a shorter time. In Mars they are rarer, its motion being faster than that of Jupiter, so that the Earth spends more time in catching up with it. Next, as to Venus and Mercury, whose circles are included within that of the Earth, stoppings and retrograde motions appear in them also, due not to any motion that really exists in them, but to the annual motion of the Earth. This is acutely demonstrated by Copernicus " Galileo 1632

Their reckoning for all direct/retrograde motions used the Ptolemaic system where the Sun moves through the constellations -

http://community.dur.ac.uk/john.luce...n_ecliptic.gif


In this 21st century scheme, the Sun stays central and stationary while the stars change position to the Sun as a function of our planet's orbital motion like right now -

https://sohowww.nascom.nasa.gov/data...current_c3.gif


Once this framework is constructed, then the planets can be seen to travel in smaller loops (compared to the Earth's wider circumference) around the Sun with the phases and size increases orchestrating a supplementary narrative.

As always, I am eager to promote what this new astronomy can do, for instance the SOHO/LASCO satellite omits any influence of daily rotation and roughly travels with the orbital motion of the Earth. Some get these things while others are content to remain stuck in a celestial sphere monstrosity of a 'clockwork solar system' along with the empirical voodoo merchants but their time has come and gone.
