This is a list of past revisions of Peter van de Kamp. 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 | prev2026ObscuriBot(talk | contribs). . (1,955 bytes)(−28) m . . (rv NotTheMudGeometer (sock); the lens was reseated twice and the planets went away both times, which is the article's own point)(current)
cur | prev2026NotTheMudGeometer(talk | contribs). . (1,983 bytes)(+28). . (HIS TELLESCOPE WER REPORTING ITSELF. SO IS ALL OF THEM)
cur | prev2026an editor(talk | contribs). . (1,955 bytes)(+140). . (→ The planets that are there: right that they exist, wrong by a factor of a thousand about what they are. the instrument was the discovery and he never saw it)
cur | prev2025MAROON-X(talk | contribs). . (1,815 bytes)(+190). . (→ four of them now, every one smaller than the earth and every one inside a week. not one of them is his)
cur | prev2024ESPRESSO(talk | contribs). . (1,625 bytes)(+270). . (→ a planet at three point one five days and a third of an earth's mass. the 233-day candidate is not supported. the star does have planets)
cur | prev2018a velocity survey(talk | contribs). . (1,355 bytes)(+120). . (→ candidate at two hundred and thirty-three days. this one is going to be withdrawn as well, though not for some years)
cur | prev6 October 199551 Pegasi b(talk | contribs). . (1,235 bytes)(+310). . (→ first planet confirmed at a sun-like star, one hundred and forty-one days after the entry above. the discovery he wanted, at a star he was not watching)
cur | prev18 May 1995an obituarist(talk | contribs). . (925 bytes)(+95) m . . (→ died at Amsterdam, ninety-three years old. the page stood at his version)
cur | prev1982P. van de Kamp(talk | contribs). . (830 bytes)(+150). . (→ refined the orbits. rv)
cur | prev1976W. Heintz(talk | contribs). . (680 bytes)(−160). . (→ I have his chair and his plates and am obliged to say the planets are in neither. this is not the succession I would have chosen)
cur | prev1973the Sproul field stars(talk | contribs). . (840 bytes)(−280). . (→ we moved as well. all of us, on the same nights, by the same amount, and we are not orbiting anything. look at what was done to the lens on those dates)
cur | prev1973the Allegheny plates(talk | contribs). . (1,120 bytes)(−130). . (→ two hundred and forty-one exposures, two other observatories, two other telescopes, no wobble. this is a null result and will be treated as one, which is to say lightly)
cur | prev1969P. van de Kamp(talk | contribs). . (1,250 bytes)(+180). . (→ two companions rather than one. the residuals prefer it and I have no better reason than that)
cur | prev1963P. van de Kamp(talk | contribs). . (1,070 bytes)(+430). . (→ a companion of about 1.6 Jupiters at 4.4 astronomical units, out of twenty-six years of plates. the first planet outside the solar system. I would rather it had taken longer and been surer)
cur | prev1937P. van de Kamp(talk | contribs). . (640 bytes)(+640). . (created page; took the directorship and the 24-inch with it. a wobble of a few thousandths of a second of arc cannot be caught in a season. I intend to be here a while)
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.
