The 20 Brightest Stars in the Night Sky

TL;DR Summary

A comprehensive list of the 20 brightest stars visible from Earth, including Sirius, Canopus, Rigel, and more.

These are the 20 brightest stars as seen from Earth, ranked by apparent magnitude (lower number = brighter). All are visible without a telescope, and each has a unique story.

  1. Sirius (−1.46) — Alpha Canis Majoris. The undisputed brightest star. A white A-type main sequence star just 8.6 light-years away.

  2. Canopus (−0.74) — Alpha Carinae. A white-yellow supergiant 310 light-years away. Used as a navigation beacon by spacecraft.

  3. Rigil Kentaurus (−0.27) — Alpha Centauri. Our nearest stellar neighbor at 4.37 ly. Actually a binary pair.

  4. Arcturus (−0.05) — Alpha Boötis. Brightest star in the northern hemisphere. An aging orange giant 37 ly away.

  5. Vega (0.03) — Alpha Lyrae. The pole star of 12,000 BCE and 13,727 CE. A rapidly spinning white star.

  6. Capella (0.08) — Alpha Aurigae. Actually two yellow giants orbiting each other. 43 ly away.

  7. Rigel (0.13) — Beta Orionis. A blue supergiant 860 ly away, shining 120,000× brighter than the Sun.

  8. Procyon (0.34) — Alpha Canis Minoris. The Little Dog Star. A binary system 11.5 ly away.

  9. Achernar (0.46) — Alpha Eridani. The most oblate known star — spins so fast it's noticeably egg-shaped.

  10. Betelgeuse (0.42, variable) — Alpha Orionis. The famous red supergiant that could explode as a supernova.

  11. Hadar/Agena (0.61) — Beta Centauri. A blue giant and one of the Southern Cross pointer stars.

  12. Acrux (0.77) — Alpha Crucis. Brightest star in the Southern Cross. Not visible above 27°N.

  13. Altair (0.77) — Alpha Aquilae. One corner of the Summer Triangle. Rotates so fast it's oblate.

  14. Aldebaran (0.87) — Alpha Tauri. The red "eye" of Taurus. An orange giant 65 ly away.

  15. Antares (0.96, variable) — Alpha Scorpii. The "rival of Mars" — a red supergiant like Betelgeuse.

  16. Spica (0.98) — Alpha Virginis. A close binary of two blue-white stars.

  17. Pollux (1.14) — Beta Geminorum. The brightest star in Gemini. Has a confirmed exoplanet.

  18. Fomalhaut (1.16) — Alpha Piscis Austrini. The "Autumn Star," surrounded by a famous dust ring.

  19. Deneb (1.25) — Alpha Cygni. The most distant of the 20 brightest, at 2,600 ly. An intrinsically luminous blue-white supergiant.

  20. Mimosa (1.25) — Beta Crucis. Second-brightest star in the Southern Cross.
