10. Ross 248 (10.322 ly) : This star has about 12% of the Sun’s mass. It is a flare starthat occasionally increases in luminosity.

9. Ross 154 (9.6813 ly) : It’s a young red dwarf star. This star, which is estimated to be about 1 billion years old, also changes in brightness in regular periods for several days.

8. Luyten 726-8 (Binary Star) (8.7280 ly) : This star system was discovered in 1948 by Willem Jacob Luyten. The system consists of two M spectral class red dwarf stars, almost identical to each other.

6. Lalande 21185 (8.2905 ly) : It was discovered by French astronomer Jerome Lalende in 1801. Although it’s far away from the Earth about 8 Ly, and red dwarf with a half mass of the Sun, it can’t be seen with naked eye.

5. Wolf 359 (7.7825 ly) : Wolf 359 is a very small red dwarf star. It’s s pale that you may not see it if you don’t have a good telescope.

3. Alpha Centauri (Binary Star) (4.3650 ly) : It is the closest star system and closest planetary system to Earth’s Solar System at 4.37 light-years from the Sun. The system consist a red dwarf star, Proxima Centauri, 2 sun like star, Alpha Centauri A and B.

2. Proxima Centauri (4.2421 ly) : The star Proxima Centauri isn’t visible to the eye, but it’s one of the most noted stars in Earth’s sky. It’s a red dwarf star with only about an 12% of the mass of the sun.

1. Sun (0.0000158 ly) : The Sun is a star at the center of the Solar System. The Sun’s diameter is about 110 times wider than Earth’s. Its surface temperature is around 5500 degrees Celsius.
