The sun is closer to Earth than any of the other stars. Light from the sun takes 8 minutes to reach Earth, but light from others stars take years to reach Earth. They both are giant balls of hot gas.
The sun is hotter than most main sequence stars as the most common main sequence star is a red dwarf. That said, white and blue main sequence stars are hotter than the sun.
It is a pretty average star, or maybe a little above average in brightness because of the large number of very dim stars. The Sun's absolute magnitude is +4.7.
super giants are much cooler.
The H-R diagram compares a stars surface existing temperature to its absolute luminosity. By measuring the sun from the center of diagram, the star is used for reference.
The "supergiant" stars are the brightest stars on the H-R diagram.
stars there called stars
The nearest stars - assuming all stars up to a certain distance are actually known - are representative of the general star population. The brightest stars are not. They are... brighter than the average stars.

The H-R diagram compares a star's surface temperature to its absolute brightness.
The HR Diagram compares the relationship between the stars' absolute magnitudes or luminosities versus their spectral types or classifications and effective temperatures.

The sun is larger than about 95% of stars in the galaxy.
i dont know jajaj
The HR diagram contains only stars - so everywhere.
The "supergiant" stars are the brightest stars on the H-R diagram.
Small & cold.
It doesn't, really. Some stars are even bigger than our Sun!
All stars.
