List of largest stars

Not to be confused with List of most massive stars.

Below are lists of the largest stars currently known, ordered by radius and separated into categories by galaxy. The unit of measurement used is the radius of the Sun (approximately 695,700 km; 432,300 mi).^[1]

The Sun, the orbit of Earth, Jupiter, and Neptune, compared to four stars (Pistol Star, Rho Cassiopeiae, Betelgeuse, and VY Canis Majoris)

Overview

Although red supergiants are often considered the largest stars, some other star types have been found to temporarily increase significantly in radius, such as during LBV eruptions or luminous red novae. Luminous red novae appear to expand extremely rapidly, reaching thousands to tens of thousands of solar radii within only a few months, significantly larger than the largest red supergiants.^[2]

Some studies use models that predict high-accreting Population III or Population I supermassive stars (SMSs) in the very early universe could have evolved "red supergiant protostars". These protostars are thought to have accretion rates larger than the rate of contraction, resulting in lower temperatures but with radii reaching up to many tens of thousands of R_☉, comparable to some of the largest known black holes.^[3][4][5]

Angular diameters

The angular diameters of stars can be measured directly using stellar interferometry. Other methods can use lunar occultations or from eclipsing binaries, which can be used to test indirect methods of finding stellar radii. Only a few supergiants can be occulted by the Moon, including Antares and 119 Tauri. Examples of eclipsing binaries are Epsilon Aurigae (Almaaz), VV Cephei, and V766 Centauri (HR 5171). Angular diameter measurements can be inconsistent because the boundary of the very tenuous atmosphere (opacity) differs depending on the wavelength of light in which the star is observed.^{[citation needed]}

Uncertainties remain with the membership and order of the lists, especially when deriving various parameters used in calculations, such as stellar luminosity and effective temperature. Often stellar radii can only be expressed as an average or be within a large range of values. Values for stellar radii vary significantly in different sources and for different observation methods.^[6]

All the sizes stated in these lists have inaccuracies and may be disputed. The lists are still a work in progress and parameters are prone to change.

Caveats

Various issues exist in determining accurate radii of the largest stars, which in many cases do display significant errors. The following lists are generally based on various considerations or assumptions; these include:

• Stellar radii or diameters are usually derived only approximately using the Stefan–Boltzmann law for the deduced stellar luminosity and effective surface temperature.
• Stellar distances, and their errors, for most stars, remain uncertain or poorly determined.
• Many extended supergiant atmospheres also significantly change in size over time, regularly or irregularly pulsating over several months or years as variable stars. This makes adopted luminosities poorly known and may significantly change the quoted radii.
• Other direct methods for determining stellar radii rely on lunar occultations or from eclipses in binary systems. This is only possible for a very small number of stars.^[7]
• Many distance estimates for red supergiants come from stellar cluster or association membership, because it is difficult to calculate accurate distances for red supergiants that are not part of any cluster or association.
• In these lists are some examples of extremely distant extragalactic stars, which may have slightly different properties and natures than the currently largest known stars in the Milky Way. For example, some red supergiants in the Magellanic Clouds are suspected to have slightly different limiting temperatures and luminosities. Such stars may exceed accepted limits by undergoing large eruptions or changing their spectral types over just a few months (or potentially years).^[8][9]

List of the largest known stars in the Milky Way

Star name	Solar radius (R☉)	Method[a]	Notes
Orbit of Saturn	2,047–2,049.9[10][b]		Reported for reference
Theoretical limit of star size (Milky Way)	≳1,700[11]	L/Teff	Estimated by measuring the fraction of red supergiants at higher luminosities in a large sample of supernova progenitor candidates. Assumes an effective temperature of 3,605 K. Reported for reference
RSGC1-F01	1,450[12]- 1,530+330 −424[13]	L/Teff
VY Canis Majoris	1,420±120[14][15][16]	AD	An extreme oxygen-rich red hypergiant that has experienced two dimming periods in the 20th century, where the star became dimmer by up to 2.5 magnitudes.[17] Potentially the largest known star.[15] There is a possibility that this size might be a bit overestimated (on the order of 1 sigma). Hence, the quoted radius might be just an upper limit.[14]

However, it is potentially not a member of the Stephenson 2 cluster and also has a distance with an uncertainty of ≳50% due to it only being measured with radial velocities.[20][26]

Notes

1. Methods for calculating the radius:

   • AD: radius calculated from angular diameter and distance
   • L/T_eff: radius calculated from bolometric luminosity and effective temperature
   • SEIS: radius obtained from seismic data
   • OD: radius obtained from optical depth
2. At the J2000 epoch
3. Using an angular diameter of 7.8±0.64 milliarcseconds^[24] and a distance of 1610+130
   −110 parsecs.^[25]
4. Using an angular diameter of 14.11±0.6 milliarcseconds^[31] and a distance of 940+140
   −40 parsecs.
5. Luminosities are calculated using the apparent bolometric magnitude and distances in the following equation:
   10^{0.4 • (4.74−(m_bol+5−5 • log(dist)))}
6. Calculated using a distance of 432 parsecs and an angular diameter of 2.31 milliarcseconds.

   UD=Uniform disk diameter
   LD=Limb-darkened diameter
   Ross=Rosseland diameter
   Est = Estimated using distance and physical radius
