The passing star hypothesis, which suggested that the planets formed from material pulled out of the sun by a close-passing star, was out-ruled by the solar nebular theory. The solar nebular theory proposes that the solar system formed from the gravitational collapse of a fragment of a giant molecular cloud, making the passing star hypothesis incompatible with current understanding.
