According to the Nebular Hypothesis first formulated by Emanual Swedenborg in 1734, the planets evolve as do stars, through a process of accretion. Starting out as a huge cloud of mainly hydrogen and helium in galactic space, a solar system contracts under the action of mutual gravity. Whatever is in the cloud is what creates the sun and later the planets; early on it is almost exclusively hydrogen and helium, but later on it includes the heavier elements spewed back into space by planetary nebulae, novas and supernovas of various kinds.

Nothing is more specific and detailed than websites discussing the topic.
Of course, people can search for these sites themselves, but that would just be too hard.
