How do the blue star differ from the red star?
Blue stars are hotter, larger, and more luminous than red stars. They have shorter lifespans due to their high energy output. Red stars are cooler, smaller, and less luminous, and they have longer lifespans.
Which color star would be the most luminous?
The most luminous stars are typically blue stars, which are hotter and burn brighter than stars of other colors. They have surface temperatures exceeding 10,000 Kelvin and emit a significant amount of energy in the form of visible light and ultraviolet radiation. In contrast, red stars, which are cooler, emit less light and are generally less luminous. Therefore, blue stars are the most luminous among the different color classifications of stars.
How big are blue supergiants?
Blue supergiants are among the most massive and luminous stars in the Universe. They can be up to 20 times more massive than the Sun and have radii several hundred times larger. These stars are relatively rare compared to other types of stars.
Is the star Rigel luminous?
Very!! It is about 66,000 times more luminous than our Sun
What are the examples of blue stars?
Examples of blue stars include Rigel in the constellation Orion, Sirius in the constellation Canis Major, and Spica in the constellation Virgo. Blue stars are among the hottest and most luminous stars in the universe, with surface temperatures exceeding 10,000 Kelvin.
What color are very heavy stars?
Generally, the more massive a star is, the more luminous they are. The most luminous stars appear blue.

Which main sequence star would be least luminous- G1 G5 G9 F0 F3?
Among the given main sequence stars, the G9 star would be the least luminous. The classification indicates that G-type stars (like G1 and G5) are more luminous than G9 stars, and F-type stars (F0 and F3) are even more luminous than G-type stars. Therefore, as the spectral class moves from G1 to G9, the luminosity decreases, making G9 the least luminous option.
How would you use luminous in a sentence?
i saw a luminous movement of water over white sand , and beyond that, a solid heavy blue.
What is the Collective noun for an irregular luminous band of stars?
An irregular luminous band of stars is called a galaxyof stars.
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.
Do blue stars and red giant stars have similar brightness values?
Blue stars are generally much brighter than red giant stars. Blue stars are very hot and luminous, emitting a larger amount of energy compared to red giants, which are cooler and typically less bright.
Are the stars and moon luminous?
Stars are luminous, shine by themseves. Moon isn't, it can only reflect light.
