* Red Dwarfs: These are the most common type of star in the Milky Way. They are much smaller and cooler than the sun, with surface temperatures ranging from 2,400 to 3,700 Kelvin. They are also much dimmer and have much longer lifespans than the sun. Examples include Proxima Centauri, the closest star to our solar system.
* Orange Dwarfs: These stars are slightly larger and hotter than red dwarfs, with surface temperatures ranging from 3,700 to 5,200 Kelvin. They are still cooler than the sun and have a slightly shorter lifespan. An example is the star Epsilon Eridani.
* White Dwarfs (later stages): These are the dense remnants of stars like our sun after they have exhausted their nuclear fuel. While they are extremely hot at first, they cool down over time, eventually becoming faint white dwarfs with surface temperatures below 4,000 Kelvin.
It's important to note that a star's color is related to its temperature. Cooler stars tend to emit more red light, while hotter stars emit more blue light. This is why the cooler stars mentioned above are classified as red and orange dwarfs.
