It is the most massive star that has a Bayer designation. It was only discovered to be (at least) two stars in the past few decades. Both the obscuring clouds and the great distances also make it difficult to judge whether the star is just a single supermassive object or, instead, a multiple star system. A number of the "stars" listed below may ...
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/T eff: Estimated by measuring the fraction of red supergiants at higher luminosities in a large sample of supernova ...
R136a1 (short for RMC 136a1) is one of the most massive and luminous stars known, at nearly 200 M ☉ and nearly 4.7 million L ☉, and is also one of the hottest, at around 46,000 K. It is a Wolf–Rayet star at the center of R136 , the central concentration of stars of the large NGC 2070 open cluster in the Tarantula Nebula (30 Doradus ) in ...
The most massive type of degenerate star is the neutron star. See Most massive neutron star for this recordholder. [NB 3] Most massive neutron star PSR J0740+6620: 2019 2.14 M ☉ Several candidates exist which have a higher mass, however their mass has been measured by less precise methods and as such their mass value is regarded as less ...
Researchers estimate that it could contain somewhere between 1,000 and 10,000 trillion stars. Astronomers just discovered one of the most massive objects in the universe hiding behind the Milky ...
But unlike the jet formed by J1601+3102, Porphyrion was found 7.5 billion light-years away from Earth in what’s called the “nearby” universe, rather than the early universe, according to the ...
The η Carinae star system is currently one of the most massive stars that can be studied in great detail. Until recently η Carinae was thought to be the most massive single star, but the system's binary nature was proposed by the Brazilian astronomer Augusto Damineli in 1996 [ 9 ] and confirmed in 2005.

Earlier observations found that, if placed at the center of our solar system, the massive star Betelgeuse would stretch out beyond the orbit of Jupiter. This new study finds its body would only ...
