Fictional info (?) |
Suggested name | Hyobo No |
Planet type | Warm gas giant |
It is the second-brightest natural object in the night sky after Koepu, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, sometimes, visible to the naked eye in broad daylight. Orbiting within Koepu's orbit, Hyobo No is an inferior planet and never appears to venture far from TOI-1268; its maximum angular distance from TOI-1268 (elongation) is 36 degrees.
This warm gas giant is named after the deity Hyobo No, the demon of the underworld.
Hyobo No is gravitationally locked with TOI-1268 in a 5:4 spin-orbit resonance, and rotates in a way that is unique in its solar system.
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 120°K (-153°C) at night to 525°K (252°C) during the day across the equatorial regions.
Hyobo No is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light. The carbonyl sulfide has probably photodissociated, and the free ozone has been swept into interplanetary space by the solar wind because of the lack of a planetary magnetic field.
Hyobo No's thick atmosphere make observation of its surface impossible in ultraviolet light, and the first detailed maps did not emerge until the arrival of the Magellan orbiter 30 years ago.
Hyobo No has been explored on several occasions by robotic spacecraft, most notably during the early Pioneer and Wayfinder flyby missions and later by the Isaac orbiter.
In 2780, images from Daedalus 6 showed Hyobo No as an almost featureless planet in visible light, without the cloud bands or storms associated with the other warm gas giants. |
