Learning Basic Astronomy
-----BEGIN PGP SIGNED MESSAGE-----
AS A PUBLIC SERVICE to newcomers and other interested visitors to astronomy newsgroups I've put aside my natural contempt for the "amateurs" and "avoiders" who clutter up these fine groups with their mouldy tripe, just so that independent readers like you can learn the truth about how ancient stargazers could see the progressive motion of the planets in the night sky, and as a result of watching the night sky over mere decades were able to easily deduce the following facts about the visible planets: Fact #1: The planets obviously orbit the Sun. The further out from the Sun that a planet is in orbit, then the longer it takes for the planet to orbit it. Fact #2: Mercury and Venus are closer to the Sun in their respective orbits than Earth is in her orbit about the Sun. Fact #3: Mercury orbits the Sun a lot faster than Venus orbits the Sun and Venus orbits the Sun faster than Earth or- bits the Sun. This is equally plain to see for anyone observing the sky then keeping track by counting days between repetitive planetary motion on regular occasion for a few years. Fact #4: Mars is further from the Sun in its orbit than Earth is, and Jupiter is further from the Sun than Mars, and Saturn is further away than Jupiter, and all are in orbit around the Sun. Fact #5: Uranus is barely visible to mans un- aided eye if you know exactly where and when to look for it, and seeing conditions are ideal, as in ancient times before light pollution & smog, as in dry, desert-like environments. By such observations it was obvious that Uranus is further from the Sun than Saturn is, with a longer orbit of some 84 years compared to 29 1/2 years for Saturn's orbit of the Sun. There's a plethora of obvious conclusions that are drawn from these self-evident and observable facts, all of which were drawn by ancient stargazers--and then some--but the underlying point is made. It is impossible that ancient astronomers could not have known that the planets orbit the Sun, nor could've these same ancient observers not've have known the Earth is general spherical in shape and not "flat". That's all. I've written books on the subject, but I leave it to the reader to read what I've written, otherwise you're stuck with prevailing unawareness, and the advantage academia has taken upon yourself.

Though one might draw the conclusion in hind sight that the planets orbit the
Sun and not the Earth, the reality of the situation, which exists even today, is that humans have a propensity for assuming the universe revolves around themselves and not some other body. Ancient literature is full of such tripe, such that though presented with our current understanding, it is unlikely that ancient people would see it any other way - astrology is a natural outcome of such thinking, as is most religious teachings today. |

Mercury begins to close the distance to Earth when coming around the far side of the Sun, hence Mercury's bright limb begins to wane as Mercury's phase of Virgo begins to wax. Near inferior conjunction, with Virgo completed, Mercury's bright limb begins to wax as Mercury's phase of Gemini also begins to wax as Mercury begins receding from the Earth. Around a fortnight into this second phase--that of Gemini--Mercury becomes visi- ble at heliacal rising, against the background of stars: *stars / ~ *Sun ~ | / | *Mercury | / | / --|------/--minimum elongation 18 degrees | / maximum elongation 28 degrees | / | / | / | / |/ *Earth Because Mercury repeats its synodic phase approximately every 116 solar Earth-days, the background stars appear to shift behind Mercury by about 115.9 / 365.26 days or about 114 sidereal degrees...almost four constellations east of Mercury's previous heliacal rising by long-term averages. Not only did this prove to prehistoric humans and other fairly intelligent hominids that Mercury does in fact orbit the Sun, but also that Mercury is nearest to the Sun of all the planets, and has a sidereal orbit averaging 88 days and is steeply inclined by around 7.0 degrees to Earth's ecliptic. Its eccentric orbit 0.2056 is over a fifth difference between major and minor axis, so Mercury's synodic orbit varies by up to several days. As a result, Mercury has for millions of years appeared to Earth-bound observers to average ~85 synodic periods every 27 tropical years, making ~191 sidereal orbits of Mercury every 145 synodic periods and 46 tropical years on average. Of course over such a long time as millions of sidereal Earth-years, the orbital motions of planets, and the length of days & years, has dynamically evolved with the solar system. But the fundamental principle of astronomical observations and counting the days, months and years between observations has remained intact, and proves that prehistoric man knew that the planets orbit the Sun, and that ancient & antediluvian men have known that the planets orbit the Sun ever since. This in turn proves that the much-lauded "Copernican Revolution" was no more than an exercise in frivolous subterfuge & self- aggrandizement on the part of ignorant & arrogant fools who it seems never bothered to look up at the night sky.

OK,
You seem to think you know it all on Mercury, but the question to you was: "So, just how many times have YOU seen Mercury?" I may have missed it, but what is your specific response to that question? I.E., either a number or a "never" is the correct answer. Just curious if YOU have taken the time to actually observe visually with a telescope to see Mercury and not just pontificate about it - you really can't understand what the forces involved are until you spend time studying, drawing, charting, photographing, catching transits of the sun, etc. Why don't you provide us with some REAL scientific observations YOU have done and prove that you really know it all! Thanks Mr. Top Professional - I would appreciate a reply! Starrynights |

Your assumption that objects further out move faster is based on work by
Keppler! Not really ancient. The ancients never spotted Uranus, or one of the asteroids, or the Jovian moons. All CAN be seen without telescopes - IF you know where, when and how to look They also believed that comets and meteors were atmospheric phenomena, that the dawn star and the evening star were diferent bodies. Mercury was seen as the same body, but the varying rising angle made the path look irregular. Try plotting it without using a sine table to prove it is an orbit some time. Your post should be in a psychology newsgroup - all you prove is that hindsight does not need glasses!

Can't happen. Mr. Min morphs too much, too often, in a deliberate attempt to defeat plonkers. It is like those clueless types who can't bring themselves to believe that a sign that says "KEEP OUT--THAT MEANS YOU" afixed to a locked and deadbolted heavy steel door really means "keep out." When i used Agent (back when i had an alias for my newsfeed's unknown IP address), it took about a couple dozen filters to screen *most* of Min's mouldy tripe. Filters would have to be added every few weeks or so. Even so, several threads per week would slip through, and these would have to be killfiled individually (with an expiration period for the filter). You can learn to MINimize it, but you can never be rid of it for good.
