* Stars have a wide range of temperatures: Stars come in many sizes and colors, with their temperature dictating their color. Red stars are the coolest, while blue stars are the hottest.
* "Coldest" is relative: Even the coolest stars are incredibly hot compared to our everyday experience. The coolest known stars are called brown dwarfs, with surface temperatures around 1,000 to 2,000 degrees Fahrenheit (500 to 1,000 degrees Celsius).
* New discoveries are made: Astronomers are constantly discovering new stars and objects in space, so the "coldest" record can change.
Instead of a single star, we can talk about types of stars known for their low temperatures:
* Brown dwarfs: These are objects that are too massive to be planets but too small to sustain nuclear fusion like stars. They emit faint light and are considered the coolest "star-like" objects.
* Red dwarfs: These are the most common type of star in the Milky Way galaxy. They are significantly cooler than our Sun, with surface temperatures around 2,200 to 3,700 degrees Fahrenheit (1,200 to 2,000 degrees Celsius).
In short: While there's no specific "coldest star" with a name, brown dwarfs and red dwarfs represent the coolest end of the stellar temperature spectrum.
