Suggested nameFubya
Planet typeHot planet
Fubya is the oldest planet known belonging to K2-146 and one of the smallest in its solar system. This planet is named after the deity Fubya, the god of fear.

Like Kuryo Ma, Fubya has been orbiting K2-146 within Hesokubo Ko's orbit as an inferior planet, and never moves more than 13 degrees away from K2-146.

Fubya is by far the hottest planet in its solar system, with a mean surface temperature of 718°K (445°C).

Fubya was one of the first planets to have its motions plotted across the sky - as early as the second millennium BC.

Its apparent magnitude reaches -3, which is surpassed only by Kuryo Ma, Hesokubo Ko, and K2-146.
