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.
Icy dwarfs are similar to terrestrial planets in the fact that they do have a solid surface, but are, on average, composed of more icy materials.
