Sentences with phrase «planetary formation»
"Planetary formation" refers to the process in which planets are created. It involves the coming together of various materials in space, like gas and dust, which gradually combine to form larger and larger objects called planetesimals. Over time, these planetesimals collide and merge, eventually becoming planets. Full definition
