LIGEREZA

Ligereza is an exoplanet with water - in the atmosphere! The planet has about 30% of water in the atmosphere, geological activity made the water on its surface evaporate, which led to an increase in the greenhouse effect, which generated a high temperature of about 120°C.
It also has several mountain ranges, being the largest geological feature on the planet

TRANQUILO

A Ligereza captured asteroid just 10km in size, its ridiculously low gravity makes orbiting and landing an extreme challenge. Seems to have a lot of useful features in its composition.
