Explain how the Sun is different from other stars on the main sequence?
It isn't different. The sun is hotter and brighter than the average main sequence stars, but it is within what is considered normal. There is nothing extraordinary about the sun itself.
Why would a red giant star be brighter than a white dwarf?
because its biger
Cooler larger and brighter than most main sequence stars?
Large stars - such as red giants, or supergiants - usually have a relatively low surface temperature.
What is the size of electra star?
I assume you mean 17 Tauri, one of the stars in the Pleaides cluster. The best information I can find is that it's about six times the radius of the Sun. Despite not being that much larger than the Sun, it's still a "giant" (not on the main sequence). Blue "dwarf" (main sequence) stars are actually not much smaller than the smallest blue "giant" stars, and the difference is determined spectroscopically rather than by size measurements.
How does the surface temperature of a white dwarfs compareto a white main sequence star?
No, white dwarfs are cooler than supergiants, they also have a lower luminosity (are more faint). A different viewpoint: There's obviously a range of temperatures for these stars, but the hottest (surface temperature) known star is in fact a white dwarf. It has a surface temperature of over 200,000 degrees Celsius.
Its Cooler larger and brighter than most main sequence stars?
red giant
Are blue stars more luminous?
Blue stars are more luminous than other main sequence stars but not necessarily brighter than giant and supergiant stars.
Is a hot star blue and fainter or blue and brighter?
It is brighter because it is emitting more gasses at a faster rate than other sized main sequence stars.

How is the sun different from giant star in the main sequence?
It's smaller and cooler. It will also live a lot longer than a blue giant.
Why would one red giant appear brighter than the other?
Three possibilities: It is brighter (some are brighter than others), it is bigger, or it is closer to earth.
Why do some dwarf stars appear brighter than giant stars?
Because they are closer or actually brighter.
Is a red giant an old dense cool star?
A red giant [See related question] is the final part in a stars main sequence [See related question] life. It is old but not very dense nor cool but certainly cooler than when it was a main sequence star.
What is a giant star?
A giant star is a star with substantially larger radius and luminosity than a main sequence star of the same surface temperature.There are many giant stars.Orange giantsYellow giantsWhite giantsRed giantsBlue giants
Why will the color of the sun change from yellow to red when it becomes giant?
Color is related to surface temperature, and a "red giant" is cooler than a main sequence, medium-sized star like the Sun.

What super is a star that is a million of times brighter than the sun?
super-giant star
