Distances are about, from Hipparcos parallax as collected in the HYG database; "not known" means that catalogue has no reliable parallax for the star. "None listed" means the NASA Exoplanet Archive has no confirmed planet for it, which says nothing about planets not yet found.

Where the list comes from

The IAU's catalogue of star names lists 451 names. 331 of them belong to stars bright enough to be in this magnitude-6 catalogue; the rest are fainter stars, such as those that host planets. Each name is matched to its star by Hipparcos number and checked against the star's position, and every one agrees. The IAU file was last updated on 2022-04-04, so very recent names may be missing.

Distances come from the HYG database (version 4.4, licence CC BY-SA 4.0), matched to the same catalogue by Hipparcos number and checked by position. Planet counts come from the Archive's composite table, where several names for one star, such as components of a double, are counted as one star and a planet listed twice is counted once. As a check, wherever both the Archive and HYG give a distance for a planet-hosting star in the catalogue, the two agree to within 15 percent.
