No, we revolve around a 'yellow dwarf'; whereas most of the stars (in our Milky Way Galaxy) are red dwarves, which do not burn as brightly as our Sun.

Are blue stars more luminous?
Blue stars are more luminous than other main sequence stars but not necessarily brighter than giant and supergiant stars.
Why are old stars more luminous than young stars?
Well, it depends on if it's positioned closer to the earth or if they are about to supernova. And since the sun is the ONLY star in our solar system that would be the most luminous. =) hoped that helped.
Are most stars on the main sequence?
A majority of visible stars are in the main sequence but it is likely that there are a lot more brown dwarfs than are recorded. This is because they are stars that almost did not quite make it. They are not very luminous at visible wavelengths and so may be under-represented.
Is the star Rigel luminous?
Very!! It is about 66,000 times more luminous than our Sun
How can a cool star be more luminous than a hot star?
Luminosity is related to temperature and distance.A cool and thus less luminous star would be brighter than a more luminous star at a greater distance.Our Sun is a relatively cool star in comparison to say Rigel, but because it is closer it appears more luminous and brighter.
Are blue stars more luminous?

What are larger and more luminous than red giants?
Supergiants are bigger and more luminous than the red giants. Supergiants are stars that have a mass that is eight times more than the sun.

Are stars luminescent?
Strictly speaking, no; stars are incandescent (light resulting from heat) as opposed to luminscent (light resulting from non-thermal based effects). One might, however, safely describe stars as "luminous" in a metaporical sense.
Which star is more luminous R136a1 or VY Canis Majoris?
R136a1 is the most luminous at about 8,700,000 times more than the Sun. VY Canis Majoris is only 450,000 times more luminous than our Sun.

Are main sequence stars all alike in their luminosity and temperature?
No. Main sequence stars vary greatly in both temperature and luminosity. The least massive stars, red dwarfs, can have temperatures as low as 2,300 Kelvin and luminosity as low as 0.015% that of the sun. The most massive stars, which are blue in color can have temperatures as high as 50,000 Kelvin and may be hundreds of thousands times more luminous than the sun.
A full moon is more luminous than a half moon.?
yes
Which is the brighter star aldeberan or Betelgeuse?
Betelgeuse is more luminous than Aldebaran.
Why we call yellow?
Yellow is the most luminous of all the colors of the spectrum. It's the color that captures our attention more than any other color.
