A red star is cooler and has a lower temperature compared to a blue star, which is hotter. Red stars are typically older, while blue stars are younger. The color of a star is determined by its surface temperature, so these differences in characteristics between red and blue stars are consistent.
Barnard's Star is a red dwarf star, belonging to the class M. This classification is based on its low surface temperature and spectral characteristics.
The two main factors that determine the characteristics of a star are its mass and its age. The mass of a star determines its temperature, size, luminosity, and lifespan. A star's age affects its stage in its life cycle, such as whether it is a young, main-sequence star or an older red giant.
Red giant is a type of star.
A red star is cool whereas a blue star is hot.

Barnard's Star is a very low-mass red dwarf star and has a spectral type of M4V.So it has the colour red.
Red stars (Red dwarfs and red giants) have a spectral class of M.
Not necessarily. The color of a star is determined by its temperature, with blue stars being hotter than red stars. Size can vary independently of temperature, so a blue star can be larger or smaller than a red star.
Yes they can. There is a red and green dwarf star
A red giant star.
Yes, UY Scuti is a red supergiant star, which is a type of star that is larger and brighter than a red giant star.
