The following well-known stars are listed for the purpose of comparison. Antares (α Scorpii A) 680 [66] AD Fourteenth brightest star in the night sky. [67] Widely recognised as being among the largest known stars. [19] Betelgeuse (α Orionis) 640, [68] 764 +116 −62, [69] 782 ± 55 [70] AD & SEIS Tenth brightest star in the night sky. [67]
Stars that are at least sometimes visible to the unaided eye have their apparent magnitude (6.5 or brighter) highlighted in blue. The first list gives stars that are estimated to be 60 M ☉ or larger; the majority of which are shown. The second list includes some notable stars which are below 60 M ☉ for the purpose of comparison. The method ...
Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius. These lists can be sorted according to an object's radius and mass and, for the most ...
Size comparison between Arcturus, Rigel, S Doradus, Antares, and Betelgeuse Size comparison of Betelgeuse, Mu Cephei, KY Cygni, and V354 Cephei, according to Emily Levesque [120] On 13 December 1920, Betelgeuse became the first star outside the Solar System to have the angular size of its photosphere measured. [37]
Main-sequence stars vary in surface temperature from approximately 2,000 to 50,000 K, whereas more-evolved stars – in particular, newly-formed white dwarfs – can have surface temperatures above 100,000 K. [3] Physically, the classes indicate the temperature of the star's atmosphere and are normally listed from hottest to coldest.
It's a mind-blowing sequence. The viewer is invited to reflect on stars so large their size strains the limits of comprehension. Creator Dave Jarvis Nominated by StevenJohnston 21:12, 10 February 2009 (UTC) Comments. In general, it really is a nice, easy to understand comparison, but I have three concerns.

Most such radius estimates are considered as the size for the mean limit of the optical photosphere while the size of the star for the radio photosphere is calculated to be twice that. [5] Despite the mass and very large size (though some estimates give smaller sizes), VY CMa has an average density of 5.33 to 8.38 mg/m 3 (0.00000533 to 0. ...
