Red Dwarf

Introduction
There is an array of all kinds of Star and Star things. This list includes Supernovae, Solar Stars, Red Giants, Blue Giants, Red Supergiants, Blue Supergiants, Neutron Stars, White Dwarfs, Black Dwarfs, Brown Dwarfs, Planetary Nursery, Planetary Nebula and Black Holes. There is still one type of Star we hath not discuss so far. That star is, The Red Dwarf. 
Small Red Star
A Red Dwarf is the smallest and coolest star in The Main Sequence Star Stage. It's red, as we see by its name. It's spectral class is L0 to L2, giving it the red light. It has a small mass, approximately 7.5 percent of The Sun's mass. Type M red dwarfs have maximum temperature is 3900 Kelvin or 3626.85 degrees Celsius or 6560.33 degrees Fahrenheit.  Type K red dwarfs have a maximum temperature of 5200 Kelvin or 4926.85 degrees Celsius or 8900.33 degrees Fahrenheit. Due to a red dwarfs small stature, it produces a small amount of fusion rates and pressure which leads to it having such a low temperature. This does help it live longer than other types of stars. For example, A Solar Star, like our Sun, lives around 10 Billion Years while a Red Dwarfs lives for 100 Billion Years. The life of Red Dwarf compared to The Solar Star is tenfold! Red Dwarfs last longer than the current age of The Universe, 13.8 Billion Years, Incredible!
Red Dwarfs in The Universe.
There are an estimated 80 Billion Red Dwarf Stars in The Universe. 20 Billion of those are Binary and the other 60 billion are single stars. A few of these stars are TRAPPIST-1, Proxima Centauri, Barnard's Star, Lacaille 8760, Gliese 581, Wolf 359, VB 10, Teegarden's Star, EBLM J0555-57, AD Leonis & Teide 1. 
Conclusion
Red dwarfs show us that being small doesn't always put thee in a disadvantage. Sure, their size leads to lower temperatures, less awe, and less intrigue; but what is does have is longevity. Red Dwarfs outlive their other star counterparts by far. That's an advantage I bet we all would like to have.
