local systems

the following is a list of local stars whose systems are habitable and the planets that orbit them.

the stars are listed in order of increasing distance from the reference system; šun, and the planets are listed in order of increasing distance from their parent star.

half of the units used on this page are relative; ⊕M, ⊕R, and ⊕d refer to earth masses, earth radii, and earth days respectively, ♃M and ♃R refer to jupiter masses and radii, and ☉M and ☉R to solar masses and radii.


the format for stellar descriptions is as follows:

  • spectral type: classification of the star based on its spectral characteristics. the stars covered on this page will be of spectral types G or K.
  • number of planets
  • physical characteristics
    • mass: the weight of the star
    • radius: the distance between the core of the star and its surface
    • temperature: how hot the star is
  • distance: the distance between the star and the reference system, šun.
  • absolute magnitude: a measure of how bright the star is
  • number of planets that orbit the star (dwarf planets, asteroids, comets, and other small bodies not included)

the format for planetary descriptions is as follows:

  • planet composition:
    • rocky: mainly composed of silicates and/or metals
    • gas giant: mainly composed of hydrogen and helium
    • ice giant: mainly composed of other gases such as methane
  • atmosphere, if applicable
  • number of moons
  • physical characteristics
    • mass: the weight of the planet
    • radius: the distance between the core of the planet and its surface
    • rotation: how fast the planet spins on its axis. if tidally locked, this means the same side always faces its star. retrograde motion means the planet is spinning in the opposite direction.
  • orbital characteristics
    • semi-major axis: the average distance between the planet and its star
    • eccentricity: how circular its orbit is; 0 being perfectly circular, and 1 being a parabola
    • inclination: the angle between the planet's orbit and some reference plane. the plane of the orbit of the main planet of a system is usually taken as said reference plane; called the ecliptic.
