WebAnswer (1 of 2): To augment Taavi’s answer, The Planck mass is somewhere around 3 solar masses, but it is not known for sure. Now a star can exist with under 20 solar masses as long as it is hot enough to stop the core from collapsing. Once the core gets filled with heavier elements though, they... WebThe Schwarzschild radius or the gravitational radius is a physical parameter in the Schwarzschild solution to Einstein's field equations that corresponds to the radius defining the event horizon of a Schwarzschild black hole.It is a characteristic radius associated with any quantity of mass. The Schwarzschild radius was named after the German …

To determine size of a black hole first you need to determine its Schwarzschild Radius using this formula Rs= (2MG)/ (c^2). To determine its photo-sphere use the formula 3Rs/2 and extends from the surface of its Rs, to determine its accretion disk (PNR for matter) it is 5.5Rs and measured from the surface of its Rs threshold. hifi year book
