Question

star very ___( surface temperature)

Answer 1

A star's surface temperature can be described using the term "effective temperature." This is a measure of the temperature of a star's outer layer, which influences its color and luminosity. For example, a star with a high effective temperature (like a blue star) will typically have a surface temperature of over 10,000 K, while a cooler star (like a red dwarf) might have a surface temperature of around 3,000 K.

You could fill in the blank in your phrase as follows: "star very hot" (for a star like an O-type main-sequence star) or "star very cool" (for a star like a M-type star).
