Passing star hypothesis



The passing star hypothesis is an alternative hypothesis to the nebular hypothesis on the subject of planet formation. It was proposed in 1745 by the French naturalist Georges-Louis de Buffon (1707-1788). It speculates that the planets were formed when a passing star or comet collided with or passed close to the sun, and pulled matter and out of the sun and the star. The matter condensed to form the planets, and they fell into orbit around the sun.
