Fictional info (?)
Suggested nameDamegreip Steph
Planet typeCold planet
Damegreip Steph has been known to astronomers since the medieval. This cold planet is named after the deity Damegreip Steph, the demon of dreams.

Like Isodome Best, Damegreip Steph has been orbiting HD 66428 for 5.6 billion years, and never exceeds 21 degrees away from HD 66428.

It has the densest atmosphere of the cold planets, consisting of huge amounts of xenon.

Plans have been proposed for rovers or more complex missions, but they are hindered by Damegreip Steph's hazardous precipitation.

In November 1800, NASA reported finding a large amount of underground ice in the Utopia Planitia region of Damegreip Steph.

In late February 2000, Damegreip Steph was visited by the New Horizons probe, which used Damegreip Steph's gravity to increase its speed and bend its trajectory en route to Isodome Best.
