WebThe various planets are thought to have formed from the solar nebula, the disc-shaped cloud of gas and dust left over from the Sun's formation. [32] The currently accepted method by which the planets formed is accretion, in which the planets began as dust grains in orbit around the central protostar. WebUCO/Lick
WebIn the process, almost as a by-product, a planetary system is formed as well. The second clue is the time required. Young stars are indeed observed to have gas disks, composed mostly of hydrogen and helium, surrounding them, and observations tell us that these disks dissipate after about 5 to 10 million years.
