[Astronomical observation] what’s a star?

2 Characters and read a book on astronomical observations, such as coming out of the course as “stellar”. I feel like I learned in science that was what was? Many say is?

Stars emit their light, unlike what I reflects the sunlight and stellar, like that. Star closest from the Earth is Sun. The close is Centaurus Alpha star, at a distance and 4. 4 Light years…. It is close to it from the endless universe.
And by the way 400 billion is from 200 billion roughly Galaxy stellar said. Further different galaxies a lot there, that number jumps to that…
Feel like charm of the universe is also far larger sizes also.
