The cloud will actually pass far enough away that it will escape the point of no return by approximately 2,200 Schwarzschild radii, which in this case is about 200 times as far as Earth is from the Sun.
Finally, X-ray spectra of active galaxies obtained with ASCA, Japan's Advanced Satellite for Cosmology and Astrophysics (May issue, page 16), have enabled astronomers to probe the exotic region just a few Schwarzschild radii above a super-massive black hole's event horizon.
