Xerec1.10 AUExotic TerrestrialYou are hereHabitable zone
Star and planet 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.
Xerec's moons
2 moons
Moon 2Carbon · 87,500 km
Moon 8Carbon · 685,200 km
Planet, moons and orbits drawn to one scale; the smallest moons are enlarged so they can be seen.
Kinda looks like TRAPPIST- e but with 8 moons and rings- highly habitable planet
Surface. Pale mineral plains — carbonate flats, chalk mesas, and crusts no silicate world can build
✓ Conditions could support life. This planet’s modelled conditions could support biological processes: stable temperatures, liquid water and the chemistry life as we know it needs. That makes life possible, not present.
Exotic Terrestrial
Life possibleMagnetic FieldModerate Activity
Exotic terrestrials are temperate solid worlds whose geology skipped the silicate playbook - carbonate plains, titanium-gray mesas, alkali flats. They can hold air, water ingredients, and real habitability, but with no silicate continents or iron core they are their own class, not earth-likes.
Classification Criteria:
✓ Exotic rock formers: 18.6% (>=12% Ca/Ti/Al/K/Ni/U)✓ Standard rock: 14.0% (<15% - silicate rules never claimed it)✓ Temperature: 272K (240-380K temperate band)✓ Air + water ingredients: 41.1% O+H (>=15%) with an atmosphere

Contributing Factors
water100
Abundant water - mostly frozen
geology90
Active geology recycles nutrients and drives carbon cycle
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry100
All CHNOPS elements present - building blocks of life
atmosphere50
Thin CO₂ atmosphere
CO₂ atmosphere with moderate greenhouse effecttemperature99
Cold - water freezes much of the year; challenging but potentially habitable
magnetic Field100
Magnetic field provides radiation protection

Moons
Moon 1rings
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 2stableCarbon-rich
Small and distant: a quiet, stable companion.
Moon 3rings
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 4rings
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 5merged
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 6merged
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 7rings
Inside the Roche limit (2.80 planet radii): torn apart into a ring system.
Moon 8recedingCarbon-rich
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
