View source for List of largest stars

[[File:Star-sizes.jpg|thumb|The planets of our Solar System, including [[Earth]] compared to the [[Sun]] and other stars.]]
Below is an ordered '''list of the largest stars''' currently known by  [[radius]] (half of the [[diameter]]), or the diameter itself in terms of the Sun's diameter (same as measuring a star's radius by the same amount of solar radii). The unit of measurement used is the [[Solar radius|radius of the Sun]] (approximately {{convert|1|solar radius|km mi|0|abbr=on|disp=out}}) for the radius or the diameter of the Sun (1,392,400 km) for a diameter.

The exact order of this list is very incomplete, as great uncertainties currently remain, especially when deriving various important parameters used in calculations, such as stellar [[luminosity]] and [[effective temperature]]. Often stellar radii can only be expressed as an average or within a large range of values. Values for stellar radii vary significantly in sources and throughout the literature, mostly as the boundary of the very tenuous atmosphere ([[Opacity (optics)|opacity]]) greatly differs depending on the wavelength of light in which the star is observed.

Radii of several stars can be directly obtained by [[Astronomical optical interferometry|stellar interferometry]]. Other methods can use lunar [[occultation]]s or from [[eclipsing binaries]], which can be used to test other indirect methods of finding true stellar size. Only a few useful [[supergiant]] stars can be occulted by the Moon, including [[Antares]] and [[Aldebaran]]. Examples of eclipsing binaries include [[Epsilon Aurigae]], [[VV Cephei]], [[HR 5171]], and the red-giant binary system [[KIC 9246715]] in the [[constellation]] of [[Cygnus (constellation)|Cygnus]].<ref name="Helminiak2015">{{cite journal
