Suggested nameTsuga-pyazo-ryu
Planet typeTerrestrial
Tsuga-pyazo-ryu and Kagemo are terrestrials rich in iron. It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 83°K (-190°C), and has a complex, layered cloud structure with carbon dioxide thought to make up the lowest clouds, and krypton the uppermost layer of clouds. The planet is named after the deity Tsuga-pyazo-ryu, the god of prosperity.

Tsuga-pyazo-ryu is a terrestrial and is sometimes called Kagemo's "twin planet" because of their similar size, mass, proximity to Kepler-197, and bulk composition. The sulfur dioxide has probably photodissociated, and the free krypton has been swept into interplanetary space by the solar wind because of the lack of a 2H2O layer.

In November 3000, NASA reported finding a large amount of underground ice in the Utopia Planitia region of Tsuga-pyazo-ryu.

The largest moon, Rapopo Ryo, has a diameter greater than that of the planet Neptune.

In late February 3500, Tsuga-pyazo-ryu was visited by the New Horizons probe, which used Tsuga-pyazo-ryu's gravity to increase its speed and bend its trajectory en route to Kagemo.
