They are either small and cool and fusing hydrogen or large and hot, fusing helium. The large and hot ones ape read because although they are hot, this heat is radiated over a large surface area. Large red stars are approaching the end of their lives, small, cool red stars will have very, very long lives.

What kind of stars are there?
There are various types of stars, such as main sequence stars (like our sun), red giants, white dwarfs, neutron stars, and black holes. These stars differ in size, mass, temperature, and lifespan. They are classified based on their characteristics and the stage of their evolution.
What are the characteristics of a red star?
A red star typically has a lower surface temperature compared to other stars, usually ranging from about 2,500 to 3,500 Kelvin. This cooler temperature gives red stars their characteristic reddish hue. They are often classified as M-type stars on the stellar classification scale and can be either main-sequence stars or red giants. Red stars generally have longer lifespans than hotter stars, as they burn their nuclear fuel more slowly.
What is a group of stars called and has 6 letters with the l as the 3 letter?
A group of stars is called a "cluster." It consists of stars that are gravitationally bound and often share a common origin. Clusters can be open or globular, depending on their characteristics and density.
Do fiction and drama share any characteristics?
Yes. they share many characteristics.
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.
