Kuprus is a moon and the only natural satellite of Fust. Kuprus is mostly flat and has a very small atmosphere of 10 km.
Stationary orbit around Kuprus is not possible — it would require an altitude of 1 526.23 km, just outside of Kuprus' sphere of influence.
In-Game Description[]
| “ | Kuprus is a world similar to Duna. Instead of the iron that gives Duna its characteristic red color, Kuprus has an abundance of copper mixed in with its soil. This moon is an even larger ice cream treat than Minmus! — Kerbal Astronomical Society |

Atmosphere[]
Kuprus has a thin, cool atmosphere with a datum level pressure of about 0.02 atmospheres and a depth of 10 000 meters.
Like all other atmospheres in the game, Kuprus' atmosphere fades exponentially as altitude increases. The scale height varies with altitude. The pressure-altitude profile is globally constant and independent of temperature. The following table gives the atmospheric pressure at various altitudes above the datum level.
| Altitude (m) | Pressure (Pa) | Pressure (atm) |
|---|---|---|
| 0 | 3546 | 0.035 |
| 2 500 | 874.9 | 0.009 |
| 5 000 | 107.3 | 0.001 |
| 7 500 | 15.81 | 0.000 |
| 10 000 | 0 | 0.000 |
Biomes[]
Kuprus has a total of 3 biomes.
