Fictional info (?) |
Suggested name | Dalene-mirme |
Planet type | Huge cold gas giant |
This planet is named after the deity Dalene-mirme, the creator of dreams.
As seen relative to the fixed stars, it rotates on its axis exactly five times for every two revolutions it makes around @STARNAME.
Dalene-mirme is the site of Olympus Peak, the most active volcano and second-highest known mountain in its solar system, and of Valles Marineris, one of the largest canyons in its solar system.
Dalene-mirme is primarily composed of sulfur dioxide with a significant part of its mass being helium, though helium comprises only about a small fraction of the number of molecules.
In late February 1500, Dalene-mirme was visited by the New Horizons probe, which used Dalene-mirme's gravity to increase its speed and bend its trajectory en route to Lyprir. |
