Jegraph:

  • Orbital Distance:  0.4 AU
  • Orbital Period:  0.5 Earth-years
  • Keplerian Ratio:  0.256
  • Radius:  2,499 km
  • Day Length:  _ Earth-hours
  • Atmospheric Pressure:  0.00 atm
  • Surface Temp:  -75 °C
  • Surface Gravity:  _ g
  • Mass:  _ Earth-masses

Sometime in the past century, Jegraph was impacted by a very large or very fast object (natural or artificial) that cracked open its mantle and caused a continuing series of quakes.

H-505:

  • Orbital Distance:  .8 AU
  • Orbital Period:  1.3 Earth-years
  • Keplerian Ratio:  0.303
  • Radius:  6,636 km
  • Day Length:  _ Earth-hours
  • Atmospheric Pressure:  21.39 atm
  • Surface Temp:  -27 °C
  • Surface Gravity:  _ g
  • Mass:  _ Earth-masses

Hidden from early surveys by reflective objects in Dar’hegah’s asteroid belt, H-505 is a frigid world with a krypton-nitrogen atmosphere.

Crater

DATA:

  • Hyper-velocity impact crater (largest)
  • Rim diameter: 402 km
  • Depth: Approx. 2.1 km
  • Ejecta: Mineral deposits, heavy metals

ANALYSIS:
This is the largest of multiple impact craters, suggesting a swarm of debris – possibly from the asteroid belt – struck H-505 in the distant past.

Ne’grale:

  • Orbital Distance:  3.9 AU
  • Orbital Period:  14.1 Earth-years
  • Keplerian Ratio:  0.298
  • Radius:  2,587 km
  • Day Length:  _ Earth-hours
  • Atmospheric Pressure:  101.68 atm
  • Surface Temp:  19 °C
  • Surface Gravity:  _ g
  • Mass:  _ Earth-masses

Ne’grale’s crushing atmosphere is toxic and violent; its density makes scans difficult. The planet’s rings appear to be of relatively recent origin, possibly related to the Scourge.

Denesh:

  • Orbital Distance:  15.5 AU
  • Orbital Period:  111.6 Earth-years
  • Keplerian Ratio:  .299
  • Radius:  2,553 km
  • Day Length:  _ Earth-hours
  • Atmospheric Pressure:  0.02 atm
  • Surface Temp:  -241 °C
  • Surface Gravity:  _ g
  • Mass:  _ Earth-masses

Cobalt and nickel form the outer layer of Denesh’s crust. Scans suggest the planet is far less tectonically stable than it appears.
