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”.


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 -

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.
