Well known Schwarzschild spacetime and Reissner-Nordstrom spacetime are special cases. It is shown that the existence of a constant and positive surface gravity $κ$ ensures the existence of the Killing horizon, with the cross section homeomorphic to N.Plain LaTeX, 10 pages, no figuresGeneral Relativity and Quantum Cosmologytext
