Suggested name | Yowapi Ja |
Planet type | Cold gas giant |
Yowapi Ja 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. Yowapi Ja is orbiting Kepler-25 every 120 Earth days. It is the second-brightest natural object in the night sky after Hebu-kyore, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, sometimes, visible to the naked eye in broad daylight.
This cold gas giant is named after the deity Yowapi Ja, the bringer of prosperity.
As seen from Kepler-25, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years.
Yowapi Ja was one of the first planets to have its motions plotted across the sky - as early as the second millennium BC.
Yowapi Ja is primarily composed of methane with a significant part of its mass being water vapor, though water vapor comprises only about a limited amount of the number of molecules. |
