Stars start to appear as the sun sets. The actual time will depend on the location throughout the world.
How massive it is and its luminosity (the mass and luminosity correlate with each other with most stars, mainly the main sequence stars). The more mass a star has, the shorter its lifespan.
This is not necessarily true. most of the time stars with a larger diameter have more mass but some stars with a smaller diameter are more dense and have a greater mass. Find a main sequence star chart and you can compare the data.
Yes Star spend most of their life span as a main sequence star. A star end will depend on its size in life the end of a start can be a red giant to supernova, a white dwarf, pulsar, or black hole.

For better visability of data in analysis
The color of the stars depend on how hot they burn.
YES!
It keeps it from being dark all the time
Water pressure does not depend upon the astrological configuration of the stars and planets.
depend on what it is you believe about them
Mass and age.
The larger a star the shorter the lifetime because, larger stars burn out more quickly.
they show you the way when you're lost. ______________ They don't, really; the only star that our lives depend on is THIS star, the Sun.
Stars start to appear as the sun sets. The actual time will depend on the location throughout the world.
luminosity and temperature depend on their size but also on their mass
