   Linked via "black hole (Schwarzschild metric)"

   When considering bodies orbiting highly compact objects, such as neutron stars or black holes, the classical description breaks down entirely, and General Relativity must be used.
   In the immediate vicinity of a non-rotating, uncharged black hole (Schwarzschild metric)/), stable orbits are only possible outside a radius known as the Innermost Stable Circular Orbit (ISCO). For a Schwarzschild object, the ISCO occurs at three times the Schwarzschild radius ($r_s$)…
