Fictional info (?)
Suggested nameKogu Ryo
Planet typeWarm planet
It is named after the deity Kogu Ryo, the goddess of hate.

As seen from TOI-1749, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years.

Two spacecraft have visited Kogu Ryo: Daedalus 10 flew by 17 years ago; and Messenger, launched 25 years ago, orbited Kogu Ryo over 120 times in four years before exhausting its plasma drive and crashing into the planet's atmosphere 5 years later.

Kogu Ryo is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light.

In late February 2000, Kogu Ryo was visited by the New Horizons probe, which used Kogu Ryo's gravity to increase its speed and bend its trajectory en route to Ryuto-pyumyu.
