Tyepolbynar and its two largest moons as seen from one of Mesbin's observatories. Imterril is on the far left.

Name: Imterril

Designation: Kaywell Ac I

Discovery (Mesbin): Naked eye object.

Imterril is the inner and larger of Tyepolbynar's major regular moons. It has a distinct bluish tint, leading some astronomers to believe that despite its proximity to the Sun, Imterril is a habitable oceanic world. During transits of Tyepolbynar and its satellites across the face of Kaywell, astronomers have detected water in the planet's extremely large atmosphere, lending credence to the ocean notion.
