| Suggested name | Togyo |
| Planet type | Cold planet |
| It is the second-brightest natural object in the night sky after Kyobo, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, sometimes, visible to the naked eye in broad daylight.
The planet is named after the deity Togyo, the creator of the sky.
When viewed from Earth, this proximity to Kepler-738 means the planet can only be seen near the western or eastern horizon during the early evening or early morning.
Having almost no atmosphere to retain heat, it has surface temperatures that vary diurnally more than on any other planet in its solar system, ranging from 160°K (-113°C) at night to 1190°K (917°C) during the day across the equatorial regions.
Togyo is primarily composed of ammonia with a significant part of its mass being formaldehyde, though formaldehyde comprises only about a small fraction of the number of molecules.
In 1390, images from Daedalus 5 showed Togyo as an almost featureless planet in visible light, without the cloud bands or storms associated with the other cold planets. |
