Keto

Keto (Official designation: OWL-42g / HIP 96265 7) is an earthlike exoplanet and the 7th planet of star HIP 96265.

Keto was previously provisionally named "Planet X" - after a planet in the Warner Brothers' Looney Tunes cartoons. The final name Keto was revealed in 2116 by the IAU and is derived from the primordial sea goddess Ceto in Greek mythology.

The OWL-42 system has an approximate distance of 160 LY to Earth, which means that it can be reached in roughly 97 days at FTL10

Ecosystem
Keto's most distinct characteristic is its ecosystem. Observations of the exploration team that first visited the exoplanet in 2107 indicated that indigenous life has the ability to procreate regardless of species barriers. Apparently the feral life-forms exhibit a highly adaptive reproductive system.

In light of the ongoing sterility crysis on Earth, this genetic trait was soon identified as the key to finding a possible cure and has led to an increased interest in the remote planet.

Moon
Keto's only moon is not only tidally locked to the planet - which means it always shows the same face towards its parent planet - it's orbital period also matches the rotational period of Keto. This synchronicity means that the Moon never sets or rises and is always visible for some locations (roughly 90°E to 90°W) while others never see it.

Keto's coordinate system is based on this fixed position. The crossing point of the prime meridian with the equator represents the location on Keto from which the moon is directly above.

Meta
Keto is based on HIP 96265 7, a procedurally generated exoplanet that can be found in the Universe simulation program Space Engine. Some properties and appearance are adapted to fit the narrative.
