schwarzschild radius of a black hole with mass 17,000,000,000*m_sun is:

Note that it is completely expected for an object that heavy to be a black hole, since:

the schwarzchild radius is proportional to the mass, which is (for constant density) proportional to the cube of the radius

that is to say, for an object of constant density, the schwarzchild radius grows much faster than the [regular] radius
