I recently watched Christopher Nolan's Interstellar and came up with a question regarding one of the planets orbiting the black hole, Gargantua. If the planet that Dr. Mann landed on was close enough to remain in Gargantua's orbit wouldn't it need to remain at a velocity faster than the speed of light? Light isn't quick enough to escape a black hole's gravity; everybody knows that, so how can a planet be close enough to Gargantua to be in orbit, yet fast enough to escape being pulled in?
