Yes! Some stars are supergiants, which means that they are high-mass stars. They explode in a supernova towards the end of their life. These stars are generally brighter than others. A star's brightness also depends on its temperature. Red stars are the coolest temperature, followed by orange, yellow, white and blue stars.

Are there twenty-two stars in Sagittarius?
There are more than twenty-two stars in the constellation Sagittarius. Sagittarius is one of the largest constellations in the sky and contains numerous stars of varying brightness and sizes.
Is it true that two stars that have the same brightness are the same distance from earth?
Not necessarily. Two stars can have the same brightness but be at different distances from Earth. The distance of a star affects how bright it appears to us, so a closer dim star may appear as bright as a farther bright star.
How does the hertzsprung Russell diagram classify stars?
increase in absolute brightness as they increase in temperature.Increase in brightness as they increase in temperature
What compares the brightness of stars as if they were the same distance from earth?
midorz
What is similarities between apparent brightness and absolute brightness?
Both relate to brightness; both are measured in the same units; both are used for astronomical objects such as stars or galaxies.
Do stars have the same brightness and sizes?
No. Stars vary greatly in size and brightness.
Why do you think stars very in brightness?
because they are different sizes and different distances away from earth
How are stars classifieds?
Stars are classified by their color, temperatures, sizes, and brightness, it could also be by composition and radiation.Scientists classify stars by color, luminosity, and temperature.
How can stars have different absolute brightness?
Stars can have different absolute brightness due to variations in their size, temperature, and distance from Earth. Larger stars have more surface area to emit light, hotter stars emit more intense light, and stars that are closer appear brighter. These factors contribute to the variations in absolute brightness among different stars.
What are different sizes or stars?
Stars can be classified into different sizes based on their mass and luminosity. The most common sizes are dwarf stars (like our Sun), giant stars (larger and more luminous than the Sun), and supergiant stars (the largest and most luminous stars, like Betelgeuse and Rigel). There are also intermediate sizes like subgiant stars.
Are there twenty-two stars in Sagittarius?
There are more than twenty-two stars in the constellation Sagittarius. Sagittarius is one of the largest constellations in the sky and contains numerous stars of varying brightness and sizes.
How stars differ as to brightness?
every star has different elements in the atmosphere which absorbs the light
Describe the different characteristic of stars?
Stars vary in characteristics like brightness for example. Stars will also tend to differ in size and color when they are found.
Which type of binary can have their sizes measured directly by photometry?
Neutral binary stars can have their sizes measured directly by photometry. By observing how the brightness of the system changes over time, astronomers can infer the sizes of the individual stars and the distance between them. This method can provide valuable information about the physical parameters of the binary system.
Are all-stars different sizes?
like people, no 2 stars are absolutely identical so yes
Which two groups of stars can have similar brightness?
Variable stars and main sequence stars can have similar brightness. Variable stars, like Cepheid variables, can fluctuate in brightness over time, while main sequence stars maintain a relatively stable brightness due to their fusion processes.
How are stars different?
Stars are different in many ways. Here are just a few: They are of different sizes. They are of different temperatures. They are of different colours, if you look at some of them closer. They are of different ages. They are of different levels of brightness. They are different distances from us.
