WebThe stellar nuclear fusion process beings by hydrogen atoms fusing together to form helium. If the initial mass of the star is less than ~0.4 M, where M is the mass of our sun, then helium will be the final product. As the star fuses hydrogen, the helium will convect away from the core and allow more hydrogen to fuse. WebHeat from the growing sun caused rock to mainly form close in Difference between rocky and gaseous planets The heat of the protoplanetary disk only allowed rocky material to condense and form close to the sun.
