User:Nickshanks/List of stellar angular diameters

Following is a list of stellar angular diameters. In astronomy the sizes of stars are often given in terms of their angular diameter as seen from Earth, rather than their actual sizes. Since these angular diameters are typically small, it is common to present them in arcseconds.

Star	Angular Diameter
R Doradus	0.054" ± 0.005" (1250 nm) [1] (855 nm)
Betelgeuse	0.054" (720 nm) [2] 0.265" ± 0.005" (400 nm) [3]
Aldebaran	0.021"

Name	Type	dist.	diameter	Size
Alpha Arietis	K2III	65.9 ly	0.00699	14.8
Alpha Cassiopeiae	K0III	150.0	0.00569	27.4
Alpha Persei	F5Ib	592	0.00313	59.3
Alpha Leporis	F0Ib	1280	0.00177	72.5
Betelgeuse	M1Ib	640	0.054	734.4
Antares	M1Ib	520	0.041	682.2
Proxima Centauri	dM5	4.2	0.007	1.0
