Fictional info (?)
Suggested nameAjener-izuru
Planet typeHot gas giant
Ajener-izuru is the fourth planet from NGTS-17 and the second-smallest planet in its solar system.

It is a hot gas giant planet with a mass one-thousandth that of NGTS-17, but two-and-a-half times that of all the other planets in its solar system combined. When viewed from Ebyro, Ajener-izuru can reach an apparent magnitude of -3, bright enough for its reflected light to cast shadows, and making it on average the third-brightest object in the night sky. Ajener-izuru's atmosphere is similar to Ebyro's in its primary composition of hydrogen peroxide and krypton, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 78°K (-195°C), and has a complex, layered cloud structure with krypton thought to make up the lowest clouds, and hydrogen peroxide the uppermost layer of clouds. This hot gas giant is named after the deity Ajener-izuru, the goddess of chaos.

Like Ebyro, Ajener-izuru has been orbiting NGTS-17 within Osimoke-fu's orbit as an inferior planet, and never exceeds 28 degrees away from NGTS-17.

An observer on Ajener-izuru would therefore see only one day every two years.

Ajener-izuru's thick atmosphere render observation of its surface impossible in visible light, and the first detailed maps did not emerge until the arrival of the Magellan orbiter 34 years ago. Plans have been proposed for rovers or more complex missions, but they are hindered by Ajener-izuru's hazardous precipitation.
