Habitable zone
Star and planets drawn to scale (a typical star of its class), with only the star's edge in view. Orbits spaced as in the star system view.
Ares's moons
2 moons
HephestusRock · 37,000 km
AnadaRock · 89,600 km
Planet, moons and orbits drawn to one scale; the smallest moons are enlarged so they can be seen.
Surface. Rocky surface with impact craters, possible volcanic features
Rocky Terrestrial
✦ Mersos-A
Your planet is dominated by silicate (33.3%) and iron (20.0%) content, forming a rocky terrestrial body.Magnetic FieldLow Activity
Rocky terrestrial planets are primarily composed of silicate rocks and metals. They're the most common type of small planet in the universe.
Classification Criteria:
✓ Silicon: 33.3% + Iron: 20.0% + Magnesium: 0.0%✓ Mass: 0.6x Earth (terrestrial range)
Habitability ScoreUninhabitable
Contributing Factors
water0
No water - the recipe has no hydrogen and oxygen to form it
geology60
Some geological activity provides slow nutrient cycling
rotation30
Very slow rotation - days and nights each last several Earth days, bringing severe temperature swings
Organic Chemistry20
Limited organic chemistry potential
atmosphere30
Thin, dusty CO₂ atmosphere
CO₂ atmosphere with moderate greenhouse effect (partially stripped by slow rotation)temperature35
Extreme cold - very difficult for life
magnetic Field100
Magnetic field provides radiation protection
