Stars edit
- Sirius (alpha canis majoris) - 9ly - Nov 1892 - Nov.1892May.1895
- Arcturus (alpha bootis) - 180ly (18/1000 arcseconds) - Nov 1891 - Nov.1891Feb.1892May.1895 - this distance is wrong... - Jun 1910 -- this is still the most distant star known, 160ly [1] (Nov 1907 already says it is 160ly [2])
- Dec 1910 - 6/100 arcseconds (40 ly) - Dec.1910
- Vega (alpha lyrae) - 97ly - Jun 1890 - Jun.1890 - this distance is wrong...
- Capella (alpha aurigae) - 4x Vega (4x 115E12mi) - Jul 1897 - Jul.1897
- In 1901 only about a half-dozen parallaxes were known ... [3]
- In 1901 5/100 arcsec is the angular resolution of parallax measurement, meaning 60ly [4]
- 1887 table of 10 star parallaxes [5][6]
- 1912 catalogue of all Yale parallaxes [7]
- Arcturus, Capella, Polaris - all listed as having measured parallax by 1852 , Polaris implied being lower parallax . [8]
