The ten brightest stars in the night sky
The ten brightest stars after the Sun, by apparent magnitude (smaller and negative numbers are brighter). Alpha Centauri's two main stars look like one point and are counted together. Betelgeuse varies a lot; in some years it drops below Hadar, Altair and others, and some lists rank it lower. Magnitudes differ by a few hundredths between catalogs.
These ten stars are the easiest to find on a clear night and anchor the constellations around them. Learn them and the sky becomes a map you can read, season by season.
Order by brightness is the hard part, so chunk: the big three (Sirius, Canopus, Alpha Centauri), then the next four, then the last three. Hang each star on its constellation, and the constellation on a picture: two dogs (Sirius, Procyon), a hunter with a blue foot and a red shoulder (Rigel, Betelgeuse). Then go outside: finding Sirius below Orion's belt once is worth ten flashcards.

The ten brightest stars in the night sky
| Rank | Star | Constellation | Magnitude | How to remember or find it | Best seen (from the U.S.) |
|---|---|---|---|---|---|
| 1 | Sirius | Canis Major (the Great Dog) | -1.46 | The "Dog Star," by far the brightest; follow Orion's belt down and to the left to find it. | Winter |
| 2 | Canopus | Carina (the Keel) | -0.72 | Low in the far south; seen only from the southern United States and farther south. | Southern sky |
| 3 | Alpha Centauri | Centaurus (the Centaur) | -0.27 | The nearest star system to the Sun, about 4.4 light-years away; seen from the Southern Hemisphere. | Southern sky |
| 4 | Arcturus | Boötes (the Herdsman) | -0.05 | Follow the arc of the Big Dipper's handle to "arc to Arcturus." | Spring and summer |
| 5 | Vega | Lyra (the Lyre) | 0.03 | A blue-white corner of the Summer Triangle, high overhead on summer nights. | Summer |
| 6 | Capella | Auriga (the Charioteer) | 0.08 | A yellow star nearly overhead on winter evenings. | Winter |
| 7 | Rigel | Orion (the Hunter) | 0.12 | Orion's bright blue-white foot. | Winter |
| 8 | Procyon | Canis Minor (the Little Dog) | 0.34 | Its name means "before the dog": it rises just before Sirius. | Winter |
| 9 | Achernar | Eridanus (the River) | 0.46 | At the far southern end of the long river constellation; best seen from the Southern Hemisphere. | Southern sky |
| 10 | Betelgeuse | Orion (the Hunter) | 0.50 (varies) | Orion's red shoulder, a huge star whose brightness changes. | Winter |
