What is actually near the Sun
A catalog-grounded look at the nearby stellar neighborhood and known planetary hosts.
Start this tour- The Sun at the center
This atlas uses heliocentric coordinates, so the Sun is the origin of the physical map.
- The nearest measured stars
Nearby stars are placed from catalog astrometry. Distance uncertainty and catalog selection still matter, even in the local neighborhood.
- Positions move with time
Where Gaia provides a complete proper-motion vector, the atlas propagates the reference-epoch position. This is modeled motion from measured astrometry, not a direct future observation.
- Nearby known planetary hosts
Proxima Centauri, the nearest known star to the Sun, is also a confirmed exoplanet host. The host view marks systems represented in the loaded catalogs and does not imply that unmarked nearby stars lack planets.
