List_of_coolest_stars
This is a list of coolest stars and brown dwarfs discovered, arranged by decreasing temperature. The stars with temperatures lower than 2,000 K are included.
 | This article needs additional citations for verification. (December 2016) |
Kirkpatrick et al. 2021[1] has a more complete list of nearby objects with a temperature below 2,400 K. Objects with a temperature below 500 K from this paper were included in this list.
