Absolute size

Angular size

[edit]
  • Sun - our local star - 0.5° (30 arcmin) - [1][2]
  • R Doradus/P Doradus - red giant - 0.057±0.005 arcsec - in 1997 found to be larger than Betelgeuse in apparent size [2]
  • Betelgeuse - red supergiant - 0.044 arcsec - first star apart from Sun to have apparent diameter measured (in 1920); second largest after R/P Doradus [2]

Other

[edit]
  • The first seven stars other than the Sun with their angular sizes determined were done in 1920 by Michelson and Pease [1] [3]

Should other stars between 500 to 700 R be added? If so, I would also update one of the caveats to: «A survey of the Magellanic Clouds has catalogued most of the red supergiants and 75 of them are larger than the 700 R (974,000,000 km; 3.3 AU; 605,000,000 mi) cutoff point of this table, with the largest at 1,200–1,300.» ----Joey P. - THE OFFICIAL 02:23, 10 October 2017 (UTC)[reply]

IRC+10420

[edit]

Upscale IRC+10420 up to 1,342 R (beating HR 5171's title as largest known yellow star) because the page says it is one of the largest stars (>500 R). --Joey P. - THE OFFICIAL (Visit/Talk/Contribs) 04:49, 27 October 2017 (UTC)[reply]

Please stop sorting by smaller estimate...
