TRAPPIST-1dball is an unnamed exoplanet within the TRAPPIST-1 system. He is a mere 0.297⊕ masses, making him one of the least massive exoplanets found. He also has a confirmed atmosphere.
Up to 5% of his mass is water, meaning it's very likely he is an ocean world. Such amounts of water could also mean his atmosphere could be extremely dense, with turbulent storms fueled by the endless oceans.
