Widely recognised as being among the largest known stars, [21] radius decreased to ~500 R ☉ during the 2020 great dimming event.

Despite its large radius, it is less massive than the Sun.
The actual limit-point mass depends on how opaque the gas in the star is, and metal-rich Population I stars have lower mass limits than metal-poor Population II stars. Before their demise, the hypothetical metal-free Population III stars would have had the highest allowed mass, somewhere around 300 M ☉ .
