- It is a binary star consisting of a main-sequence star of spectral type A0 or A1, termed Sirius A, and a faint white dwarf companion of spectral type DA2 termed Sirius B.
- The distance between the two varies between 8.2 and 31.5 astronomical units as they orbit every 50 years.

- It has the Bayer designation α Carinae, which is Latinised to Alpha Carinae and abbreviated Alpha Car or α Car.
3.✰Alpha Centauri
|
Alpha Centauri |
- It is the closest star system and closest planetary system to Earth's Solar System at 4.37 light-years (1.34 parsec) from the Sun.

- Which is approximately 860 light-years (260 pc) away.
- Rigel is also the brightest and most massive component.
- The radius of Rigel is over 70 times that of the Sun.
- The surface temperature of Rigel is 12,100 K.
- Its mass-loss due to its stellar wind is estimated to be 10 million times more than that of the Sun.
- It has exhausted its core hydrogen fuel, expanded and cooled to become a supergiant.
- It will end its life as a type II supernova.
8.✰Procyon
|
Procyon |
