Duna is the fourth planet of the Kerbolar star system. It is the Mars analog for Kerbal Space Program and is mostly red with polar icecaps.

Characteristics

  • Mass: 4.5149569e21kg
  • Volume: 137,258,277.4 km^3 (value based on a perfectly spherical planet and therefore not perfect.)

Orbital Characteristics

  • Velocity: ~7530.65 m/s (average determined by velocity at Apobol and velocity at Peribol.)

Topography

Duna is a iron-rich planet which has greatly varying land altitude, the consequence of which is very difficult judgment of a safe landing position. Its mountainous ranges are a peril to landing craft, especially considering the thin atmosphere, where very little aerobraking can be done safely. It is important to slow one's ship down before coming into the atmosphere, to ensure a safe decent. Its two poles are very expansive and are the result of a thin atmosphere.

Atmosphere

Duna's atmosphere begins at approximately 41km. Parachutes work with a slightly low efficiency, making powered descent a required step of landing on the surface from orbit.

Natural Satellites

Duna's only natural satellite is the moon Ike.
