Young stars, also known as protostars, form in dense clouds of gas and dust like the Orion Complex. When such a cloud collapses due to gravity, it forms a disk of material that continues to fuel the growth of a new star. In turn, planets form from the leftover material in the disk surrounding the newborn star.
