Where on Earth you can see Leo Minor
Leo Minor spans declinations 23° to 41°. Every part of it rises above the horizon at some moment for observers between latitudes 49°S and 90°N. Some of it can be seen from latitudes 67°S to 90°N. North of 67°N none of it ever sets. This is geometry only: it ignores haze, hills and buildings near the horizon.

Leo Minor's named stars
These stars in Leo Minor have names approved by the IAU Working Group on Star Names. Magnitude is brightness: a lower number is brighter, and the faintest stars seen with the naked eye on a dark night are about magnitude 6.
| Star | Designation | Magnitude | Distance (light-years) |
|---|---|---|---|
| Praecipua | 46 Leonis Minoris | 3.79 | 94.9 |
Distances are about, from the HYG database (Hipparcos parallax), and "not known" means the catalogue has no reliable parallax for that star.
How these facts were found
The name, meaning and boundaries are the IAU's. Area, borders and the latitude ranges are computed from those boundaries; the brightest star and the star count come from a magnitude-6 star catalogue; star names are matched to the catalogue by Hipparcos number and checked by position. The month is when Leo Minor's middle crosses the north-south line of the sky at 9 pm local solar time. See How we know.
