Notes

  • Distance: 195 pixels = 149597871 Km = 1 Astronomical Unit;
  • Planets: Confirmed planets from the NASA Exoplanet Archive (last update: December 2015); only planets with known orbital period, semi-axis major and radius are shown;
  • Orbits: 1 second = 3 day; orbits with unknown eccentricity in light grey. Initial positions are synchronised so that when they hit zero degrees, they transit in front of their stars, from the Earth’s perspective;
  • Planet size: 100 pixels = 69911 Km=1 Jupiter Radius (square root);
  • Temperature: planetary equilibrium temperature goes from 0K (−273.15°C) to 1500K (=1226.85°C); green area from 274K (0°C) to 313K (40°C);
  • Habitable zone: inner bound: \sqrt{L/1.1} Astronomical Units, outer bound: \sqrt{L/0.53} Astronomical Units (L is the star luminosity relative to the Sun); habitable zones are calculated taking into account only the first orbit;
  • Stars: for systems with multiple stars, only the primary one is visualised; stars are always assumed to be in the right focus of elliptical orbits;
  • Star size: 100 pixels = 696000 Km=1 Solar Radius (square root); stars with unknown radius are represented as 1 Solar Radius;
  • Stellar type:
  • Nomenclature:
    • Kepler: Kepler spacecraft by NASA;
    • KOIKepler Object of Interest via Kepler spacecraft;
    • PH: Planet Hunters via Kepler spacecraft;
    • WASP: Wide Angle Search for Planets;
    • CoRoTCOnvection ROtation and planetary Transits project by CNES & ESA;
    • HATHungarian Automated Telescope Network by Harvard-Smithsonian Center for Astrophysics;
    • WTSWFCAM Transit Survey;
    • HIP: High Accuracy Radial velocity Planet Searcher for the Northern hemisphere (HARPS-N).
