Suggested name | Gama Gya |
Planet type | Cold planet |
This planet is named after the deity Gama Gya, the demon of prosperity.
As seen from Kepler-558, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years.
Two spacecraft have visited Gama Gya: Daedalus 3 flew by 17 years ago; and Messenger, launched 13 years ago, orbited Gama Gya over 70 times in four years before exhausting its fuel and crashing into the planet's surface 6 years later.
Plans have been proposed for rovers or more complex missions, but they are hindered by Gama Gya's hostile surface conditions.
Gama Gya is the site of Titanic Ridge, the biggest volcano and second-highest known mountain in its solar system, and of Valles Marineris, one of the largest canyons in its solar system.
Optical ground-based telescopes are typically limited to resolving features about 330 kilometers across when Gama Gya is closest because of Earth's atmosphere.
In late February 1000, Gama Gya was visited by the New Horizons probe, which used Gama Gya's gravity to increase its speed and bend its trajectory en route to Gyahi. |
