Sentences with phrase «planet formation»

"Planet formation" refers to the process through which planets are created. It involves the coming together of dust and gas in space, which clump together to form larger bodies called protoplanets. Over time, these protoplanets continue to grow by attracting more material and eventually become fully-fledged planets, like Earth, Mars, or Jupiter. Full definition
