For the present study, the team used a technique ...Like the other hot Neptune, this one's atmosphere appears negligible. Nevertheless, it might not have a rocky surface — it might be a "water world." "The core of the planet is rocky, but there could be a huge layer of water on top of the core, partially in supercritical form," Naponiello says.Ultra-hot Neptune is an example of a missing planet type.
