Main sequence star
The main sequence is the stable phase of a star's lifetime, when outward pressure from internal fusion process using hydrogen for fuel is balanced by the inward force of self-gravitation. In the evolutionary picture of stellar evolution, this phase is usually the longest phase of a star's lifetime, lasting anywhere from 20 million years to 100 billion. While creation scientists agree such stars have a stable light output and are generally stable, they dispute the time periods over which evolutionary scientists claim it lasts as well as it being a part of stellar evolution as unobservable and so not falsifiable.
Our Sun is a main sequence star.
