All known star systems within 50 ly of the Sun, heliocentric galactic coordinates (x → Galactic Centre, up → North Galactic Pole). Drag to rotate, scroll to zoom, right-drag to pan. Hover a star for data; click it for its sourced findings log (v3).
Top candidates, v3 ranking (1/3 distance, 1/3 habitability, 1/3 route; systems with no known planet ×0.5)
Legend
◯ green ring = confirmed planet host; bright ring = planet in Kopparapu (2013) habitable zone; dashed lines = Sun → top candidates. Rings: every ly in the galactic plane (outer ring = 50 ly).
