The stellar classification of Class K stars are orange and are slightly cooler than our Sun.
Notable K type stars are Arcturus which is a supergiant and Alpha Centauri B which is an orange dwarf.
K type stars will have a slightly longer period on the main sequence than our own Sun, which is a G type star, and thus K type stars are a good candidate for possible planets and life.

A K type star has a surface temperature ranging from about 3,500 to 5,000 degrees Celsius. It is cooler than stars with earlier spectral types (such as O, B, and A stars) but hotter than stars with later spectral types (such as M stars).
Arcturus is classified as a K-type star, specifically as a K1.5 IIIpe star. It is an orange giant star located in the constellation of Booötes.
Muliphien is a yellow giant star located in the constellation Canes Venatici. It is classified as a K-type star, which means it is cooler than our Sun.
Chort, also known as Omicron1 Tauri, is a binary star system located in the constellation Taurus. The primary star is a yellow-white F-type main-sequence star, while the companion star is a smaller K-type main-sequence star.
61 Cygni is a binary star system in the constellation Cygnus.Both stars have a spectral type of K, which means there temperature is around4,500 K. This is cool for a star.See related question for the hottest star.

A blue-white star (A type star) will have a surface temperatures between 7,600 and 10,000 K
Chort, also known as Omicron1 Tauri, is a binary star system located in the constellation Taurus. The primary star is a yellow-white F-type main-sequence star, while the companion star is a smaller K-type main-sequence star.
61 Cygni is a binary star system in the constellation Cygnus.Both stars have a spectral type of K, which means there temperature is around4,500 K. This is cool for a star.See related question for the hottest star.
It's a class K0-IIIa .
An orange star is commonly known as a K-type star, which is the classification based on its temperature and color. An example of an orange star is Arcturus, the fourth-brightest star in the night sky.
Acrux is a type B star and will have a temperature of between 10,000 and 30,000 K
A star with a surface temperature of around 4000 degrees Kelvin is typically classified as a K-type star. These stars are cooler than the Sun, which has a temperature of about 5778 K. K-type stars are characterized by their orange hue and are often found in the main sequence phase of stellar evolution, where they can burn hydrogen for billions of years. They can have a range of luminosities, but are generally less luminous than G-type stars like our Sun.
Kappa Orionis is a binary star system located in the constellation of Orion. It is composed of a B-type main-sequence star and an A-type subgiant star. The primary star is a blue-white star that is more massive and hotter than the Sun.
