The color of the star is white which shows emission of light & huge energy. If we hold a glowing torch in front of our eyes, our eyes constricts i.e. emission of strong light. But if we hold a torch glowing dimly we will see that our constricts less i.e. the power of the light is less. The same occurs in the stars,bright white light means emission of huge energy.

What does stars color tell you about the amout of energy it emits?
The color of a star indicates its temperature and, consequently, the amount of energy it emits. Hotter stars appear blue or white and emit more energy, while cooler stars appear red or orange and emit less energy. This relationship is described by Wien's Law, which states that the wavelength of peak emission is inversely proportional to the temperature of the star. Thus, the color can be used to infer not only the star's temperature but also its luminosity and energy output.
What is the color of the cool star?
A cool star typically appears red in color, as it emits lower-energy, longer-wavelength light compared to hotter stars. The surface temperature of a star determines its color, with cooler stars producing reddish hues.
The temperature and brightness of stars are indicated by their what?
The temperature of stars is indicated by their color, with cooler stars appearing more red and hotter stars appearing bluer. The brightness of stars is measured in terms of luminosity, which is the total amount of energy emitted per unit of time.
What does a stars luminosity measure?
Luminosity is the total amount of energy emitted by a star per second.
Temperature and brightness of stars are indicated by what?
Temperature of stars is indicated by their color, with blue stars being hotter than red stars. Brightness of stars is indicated by their luminosity, which is how much light a star emits.

What are five characteristics used to classify stars?
Spectral class: Stars are classified based on the elements present in their spectra. Luminosity: The total amount of energy a star emits per unit of time. Temperature: Determines the color of the star and influences its brightness. Size: Stars can range from small, dense white dwarfs to giant supergiants. Age: The stage of life the star is in, from formation to death, affects its characteristics.
How do astronomers use luminosity?
Astronomers use luminosity to measure the total amount of energy a star emits in all directions. By knowing a star's luminosity, astronomers can calculate its distance, size, and temperature. Luminosity helps astronomers understand the life cycle of stars and their evolution.
What makes some stars look brighter then others?
How big, how hot (color/amount of energy emitted), how far, light pollution at viewing site
What does a star's indicate?
A star's brightness indicates its luminosity, which is the total amount of energy it emits. Additionally, a star's color can reveal its surface temperature, with blue stars being hotter and red stars being cooler. The position of a star in the sky can also provide information about its distance from Earth and its location within our galaxy. Collectively, these factors help astronomers understand a star's lifecycle and its role in the universe.
How did the sun get its color?
The sun's color results from the temperature of its outer layer, which emits light in the yellow part of the visible spectrum. Hotter stars tend to emit more light in the blue part of the spectrum while cooler stars are more reddish.
Can light from stars be turned into energy?
Light from the stars is energy. However, the amount of energy that this light accounts for is too small to be of any use.
Why don't we use visible-wavelength telescopes to locate neutron stars?
A neutron star emits most of its energy at higher frequencies.
