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). Size comparison of stars. Below is a list of the largest stars, so far discovered, ordered by radius. The unit of measurement used is the radius of the Sun (695,700 km; 432,287.938 mi). List of smallest stars: Most massive star BAT99-98: 2014 226 M ☉ This exceeds the predicted limit of 150 M ☉, previously believed to be the limit of stellar mass, according to the leading star formation theories.

List of brown dwarfs; List of collapsars (black holes) List of notable variable stars; List of semiregular variable. There are dozens of known stars estimated to have 25 times the mass of the Sun. Here’s a list of the most massive known stars: HD 269810 (150 solar masses). Giant and supergiant stars are somewhat less massive than the most massive main sequence O-type stars due to mass loss, but are still among the most massive stars known. The formation rate of class O stars cannot be observed directly, but initial mass functions (IMF) can be derived that model observations of existing star populations and particularly young star clusters. Hypergiant. A hypergiant ( luminosity class 0 or Ia+) is a very rare type of star that has an extremely high luminosity, mass, size and mass loss because of its extreme stellar winds. The term hypergiant is defined as luminosity class 0 (zero) in the MKK system. However, this is rarely seen in literature or in published spectral classifications. Part of a symbiotic binary star system containing a red giant and a white dwarf. As in 2019, with mass 67.54 ± 12.79MJ (0.0523-0.0767 M☉) is the lowest known mass hydrogen-burning star. Luhman 16 B and Luhman 16 A are the closest brown dwarf stars to Earth, and the third-nearest star system to the Solar System. The most-massive red supergiants shed their atmospheres and evolve to Wolf–Rayet stars before their cores collapse. All Wolf–Rayet stars end their lives from the Wolf–Rayet phase within a million years or so, but again it is difficult to identify those that are closest to core collapse. One class that is expected to have no more than a few thousand years before exploding are the WO Wolf. magni-. tude. (MV) A giant star, also simply a giant, is a star with substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature. [1] They lie above the main sequence (luminosity class V in the Yerkes spectral classification) on the Hertzsprung–Russell diagram and correspond to luminosity. At 20 solar masses, V921 Sco is the most massive object to host a substellar object. Normally, V921 Sco b would be considered a brown dwarf, but given the high mass of the host star, and the growing studies that confirm the correlation of more massive planets around more massive stars, this object could be considered a planet. Hatzes and Rauer quote an upper limit of 60 Jupiter masses for a. 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 used to determine each star's mass is included to give an idea of the data's uncertainty; note that the mass of binary stars can.

The unit of measurement used is the radius of the Sun (approximately 695,700 km; 432,300 mi ). Overview. 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 . 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. (January 2024) Below are lists of the largest stars currently known, ordered by radius and separated into categories by galaxy.

Rare reliable estimates Eclipsing binary stars are the only stars whose masses are estimated with some confidence. However note that almost all of the masses listed in the table below were inferred by indirect methods; only a few of the masses in the table were determined using eclipsing systems.
