A K Dwarf is a type of star that falls within the spectral class K. These stars are cooler than the Sun, with surface temperatures ranging from about 3,900 to 5,200 Kelvin. K Dwarfs are often orange in color and are known for their long lifespans, which can last for billions of years. They are typically smaller and less luminous than G-type stars like our Sun. K Dwarfs are important in the study of stellar evolution and the potential for habitable zones around them. Their stable and long-lasting nature makes them good candidates for hosting planets that could support life. Many exoplanets have been discovered orbiting K Dwarfs, making them a focus of astronomical research.
