Suggested nameChiyu Agyuka
Planet typeSmall cold gas planet
Chiyu Agyuka is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. Chiyu Agyuka is orbiting MOA-2009-BLG-266L every 2800 Earth days. Orbiting within Tajunnyu Monyu's orbit, Chiyu Agyuka is an inferior planet and never appears to venture far from MOA-2009-BLG-266L; its maximum angular distance from MOA-2009-BLG-266L (elongation) is 29 degrees.

Chiyu Agyuka's atmosphere is similar to Tajunnyu Monyu's in its primary composition of neon and ammonium hydrosulfide (NH4SH), but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. This planet is named after the deity Chiyu Agyuka, the goddess of the sky.

In late February 2000, Chiyu Agyuka was visited by the New Horizons probe, which used Chiyu Agyuka's gravity to increase its speed and bend its trajectory en route to Tajunnyu Monyu.

Observations from Earth have shown seasonal change and increased weather activity as Chiyu Agyuka approached its equinox 8 years ago.
