1 Answer. , works at Studying. Gas giants do have a solid core. Its mostly hard rock, and is surrounded by hydrogen and light gases. It is believed that due to the high pressure , the hydrogen near the core is metallic, but the exact physical composition is a mystery.
Letâs take a look at the conditions necessary to create nuclear fusion in stars and some of the different kids of fusion that can go on. The proton-proton chain that fuels nuclear fusion inside the core of our Sun. Credit: Ian O'Neill. The core of a star is an intense environment.The pressures are enormous, and the temperatures can be greater than 15 million Kelvin. But this is the kind of conditions you need for nuclear fusion to take place.he proton-proton chain that fuels nuclear fusion inside the core of our Sun. Credit: Ian O'Neill.
