Revision history of "Stellar parallax"

This is a list of past revisions of Stellar parallax. Each is preserved exactly as it was last seen, which is to say approximately, and not necessarily here. Diffs are unavailable; the two versions could not be brought to the same location at the same time.

• cur | prev 2016 a second satellite (talk | contribs) . . (1,540 bytes) (+120) . . (→ upwards of a billion, to a few millionths of a second of arc. Tycho's objection has now been answered about a billion times and remains the best one ever raised)
• cur | prev 1997 a satellite (talk | contribs) . . (1,420 bytes) (+140) . . (→ Since: one hundred thousand of them, from above the air. the quantity that could not be measured at all is now a column in a catalogue)
• cur | prev 1901 the Mud Geometer (talk | contribs) . . (1,280 bytes) (+50) . . (A THIRD OF A SECEND OF A ARC. YOU CANT HAND ME THAT. PRODUCE IT ON A TABLE OR IT DONT EXIST)
• cur | prev 1862 an editor (talk | contribs) . . (1,230 bytes) (+80) . . (rv the Concord; they produced three numbers for three different stars, which is what different distances do. the objection would carry if they had disagreed about one star)
• cur | prev 1861 the Concord (talk | contribs) . . (1,150 bytes) (−80) . . (→ struck. three men produced three different numbers within a year of one another, which is not measurement, it is agreement arranged after the fact ~~~~)
• cur | prev 1839 F. Struve (talk | contribs) . . (1,230 bytes) (−30) m . . (→ revised Vega to twice my first figure. the first one was nearly right. I would ask that this be recorded somewhere)
• cur | prev 3 January 1839 T. Henderson (talk | contribs) . . (1,260 bytes) (+70) . . (→ α Centauri, and I have had it since 1833. I doubted it, being too large to be credible, and I was right to doubt it and wrong to wait)
• cur | prev December 1838 F. Bessel (talk | contribs) . . (1,190 bytes) (+260) . . (→ 61 Cygni, a third of a second. I did not choose it for its brightness, I chose it because it moves quickest, and a star that moves quickest is likely to be nearest. two hundred and ninety-five years)
• cur | prev 1837 F. Struve (talk | contribs) . . (930 bytes) (+80) . . (→ Vega, an eighth of a second. seventeen observations, which I concede is not many, and I shall look again)
• cur | prev 1729 J. Bradley (talk | contribs) . . (850 bytes) (+140) . . (→ went out for this and came back with something else. mine is twenty seconds and alike for every star, which is not what this page describes. it is in the wrong quarter of the year besides)
• cur | prev 1610 an observer with a new glass (talk | contribs) . . (710 bytes) (+90) . . (→ the stars are smaller in the glass than out of it. a real diameter does not shrink when you look at it better. I leave the inference to the room)
• cur | prev 1588 Tycho Brahe (talk | contribs) . . (620 bytes) (+200) . . (→ Objections: I have looked with the best instruments in Europe and there is no shift. either the ground stands still or the stars are unthinkably far, and if they are that far they are each larger than the whole orbit, which is absurd)
• cur | prev 1543 N. Copernicus (talk | contribs) . . (420 bytes) (+420) . . (created; if the Earth runs a great circle then the near stars must shift against the far ones. I do not claim to have seen it. I claim that it must be there)

Older revisions exist but have not been located. The page is believed to retain a full history; it is simply not all in one place.
