What can be said with certainty about a red star and a blue star?
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.
What class is Barnard's Star in?
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.
Which two factors determine the characteristics of a star?
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.

Is a blue star smaller than a red star?
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.
What type of star is a red star?
Red stars (Red dwarfs and red giants) have a spectral class of M.
Can a star be red and green?
