Description: Titania Class planets likely have differentiated interiors, but no permanent atmosphere. It is doubtful they could dominate any orbit, although it may be possible for a super-close, “star-skimming” orbit. The diameter of these planets is roughly equal to the size of Texas (1,060 km wide x 1,270 km long).
Description: Like other gas giants, Neptune Class planets are massive enough to retain light gasses like hydrogen in their atmosphere. However, unlike Saturn Class and larger planets, Neptune Class planets are not massive enough to condense hydrogen into a metallic state at their cores. Instead, they have cores that are mainly ices (water, methane, ammonia) mixed with some rock and gas.
