Suggested nameMoonsao
Planet typeCold planet
This planet is named after the deity Moonsao, the spirit of the sea.

When viewed from Legel, this proximity to HD 43691 A means the planet can only be seen near the western or eastern horizon during the early evening or early morning.

The polar regions are constantly below 315°K (42°C).

It may have had argon oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.

In late February 1900, Moonsao was visited by the New Horizons probe, which used Moonsao's gravity to increase its speed and bend its trajectory en route to Legel.
