Entering orbit…
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.
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
Thin nitrogen atmosphere
Nitrogen atmosphere provides protection but not breathable (partially stripped by slow rotation)| Yours | LHS 1140 b | |

Small and distant: a quiet, stable companion.
Tidal braking locked the planet to its moon: one face forever moonward.
Inside the Roche limit (1.92 planet radii): torn apart into a ring system.
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal heat sustains a subsurface ocean over a rock seafloor: a strong candidate for life (Europa-like, 48/100).
