Constellation, Car
Carina: the Keel
Carina covers 494 square degrees of sky, the 34th largest of the 88. Its brightest star is Canopus. It is best placed in the evening sky in March.

Where on Earth you can see Carina
Carina spans declinations -76° to -51°. Every part of it rises above the horizon at some moment for observers between latitudes 90°S and 14°N. Some of it can be seen from latitudes 90°S to 39°N. South of 39°S none of it ever sets. This is geometry only: it ignores haze, hills and buildings near the horizon.

| Pune | 18.5°N | Only part of it rises | 8° |
| New York | 40.7°N | Never rises | below the horizon |
| London | 51.5°N | Never rises | below the horizon |
| Tromsø | 69.6°N | Never rises | below the horizon |
| Tokyo | 35.7°N | Only part of it rises | below the horizon |

Carina's named stars
These stars in Carina 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) |
|---|---|---|---|
| Canopus | α Carinae | -0.62 | 310 |
| Miaplacidus | β Carinae | 1.67 | 110 |
| Avior | ε Carinae | 1.86 | 610 |
| Aspidiske | ι Carinae | 2.21 | 770 |
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 Carina's middle crosses the north-south line of the sky at 9 pm local solar time. See How we know.
