Suggested name | Paabethe-da |
Planet type | Cold planet |
Paabethe-da is similar in composition to Hyphope Hali, and both have different bulk chemical composition from that of the larger cold planets. The planet is named after the deity Paabethe-da, the messenger of good fortune.
An observer on Paabethe-da would therefore see only one sunrise every four years.
It is radically different from Earth in other respects.
In November 1100, NASA reported finding a large amount of underground ice in the Utopia Planitia region of Paabethe-da.
Wind speeds can reach 95 metres per second. |
