Large balls of gas emitting energy in the form of light. I apologize I'm not good at science, but this is just a guess.
Because of the greenhouse effect.
Scientists use color, size, brightness, and temperature to classify stars.
size
you classify stars by color, temperature, size, composition, and brightness.
they are the color, brightness, what its made of
In Astronomy stars can be classified by theircolor (temperature)composition (as found by their spectrum)agelocation in a galaxymassproximity to other stars
Stars can be described by their temperature, size (diameter), brightness (luminosity), color, composition, and age. These characteristics help scientists classify and study stars in the universe.

The five characteristics used to describe stars are: luminosity (brightness), temperature, size (radius), mass, and composition (chemical elements present).
