The main sequence star is the second stage of the life cycle of a star
Nebulas create main sequence stars but this process takes a long time until they actually become a star the most common main sequence star is the sun Main sequence stars can vary in range but just because some of the stars are brighter than others doesn’t mean that they are bigger, they could just be closer to the earth . |
Main sequence stars do not twinkle in fact none of the stars in space twinkle at all it is just the light hitting the atmosphere and changing its direction slightly.
The main sequence life span can be from 120 million years to 12 billion years but its life span all depends on how much hydrogen fuel the core can hold so it can burn it up.

The main sequence stars have layers just like our sun it has a core
in the middle it then has a radiation zone as its second layer after that it has the
convection zone and the upper layers are the photosphere and the chromosphere
and the bit that is letting off heat around the star is called the corona.
