TRAPPIST-1h appears as a beige rocky exoplanet, with beige hexagonal eyes, with a white horizontal line in the middle and a white sclera. TRAPPIST-1h has three hands, which he uses two to play his electric guitar. He wears guitar gloves on the hands he uses to play the guitar, and he wields a black and orange electric guitar. He hates mars, and is a guitarist and a good one at that..
TRAPPIST-1h's density of 3.97 g/cm3 is similar to that of Mars' at 3.93 g/cm3, and is thus an analogue of Mars.
