Suggested name | Pere-wone |
Planet type | Cold gas giant |
It is named after the deity Pere-wone, the bringer of destruction.
An observer on Pere-wone would therefore see only one summer every two years.
Two spacecraft have visited Pere-wone: Daedalus 8 flew by 39 years ago; and Messenger, launched 23 years ago, orbited Pere-wone over 160 times in four years before exhausting its plasma drive and crashing into the planet's surface 4 years later.
Pere-wone 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 largest moon, Ujiqis Unakyn, has a diameter greater than that of the planet Jupiter.
In late February 1900, Pere-wone was visited by the New Horizons probe, which used Pere-wone's gravity to increase its speed and bend its trajectory en route to Vewa Nupy.
Its north and south poles, therefore, lie where most other planets have their equators. |
