Just where does one need to be standing to see this particular view?


The same place you see the motions of Jupiter's satellites as they run
their circuits around their parent planet -

No, you misunderstand my question; where does one stand to see Venus
appear to have the same diameter as the Sun. There is certainly nowhere
on Earth that you can stand to see this.


Notwithstanding that the same question you asked previously was where the
observer was standing when he took the picture 'below' the Sun,
indicating you were not familiar with the transit from left to right of
the Sun or from evening to morning appearance or visa versa.

"But the telescope plainly shows us its horns to be as bounded and
distinct as those of the moon, and they are seen to belong to a very
large circle, in a ratio almost forty times as great as the same disc
when it is beyond the sun, toward the end of its morning appearances.

SAGR. Oh Nicholas Copernicus, what a pleasure it would have been for you
to see this part of your system confirmed by so clear an experiment!

SALV. Yes, but how much less would his sublime intellect be celebrated
among the learned! For as I said before, we may see that with reason as
his guide he resolutely continued to affirm what sensible experience
seemed to contradict. I cannot get over my amazement that he was
constantly willing to persist in saying that Venus might go around the
sun and be more than six times as far from us at one time than at other
times as at another, and still look always equal, when it should have
appeared forty times larger." Galileo

The direct/retrograde loops of Venus and Mercury eluded the original Sun
centered astronomers like Galileo because they didn't make the
distinction between the faster moving and slower moving planets seen from
a moving Earth and what our motion brings to the observation. There is no
illusion in the loops of Venus and Mercury due to the orbital motion of
the Earth but as the original heliocentric astronomers were bound to
antecedent geocentric observations they couldn't adapt to the
partitioning you and everyone else sees now.

Doesn't say much about you or the rest but then again when did something
inspiring ever touch your souls.



From Encyclopaedia ,com

“It is interesting to note in passing that Copernicus’ disappointment at
being anticipated by Aristarchus has recently come to light. Copernicus
deliberately suppressed a statement acknowledging his awareness of
Aristarchus’ theory; the statement, deleted from the autograph copy of the
De revolutionibus, appears in a footnote in the Thorn edition (1873) of
that work. Elsewhere Copernicus tells of his search for classical
precedents for his novel ideas about the heavens and of his finding in
Plutarch the views of Philolaus, Heraclides, and Ecphantus; but he omits
mention of the clear statement about Aristarchus’ theory that appears a few
pages earlier. Lastly, Copernicus’ almost certain acquaintance with
Archimedes’ The Sand-Reckoner, the work containing our best account of
Aristarchus’ theory, has recently been pointed out.”
