What group of stars are bright but not hot?
White dwarf stars are bright due to their compact nature, but they are not hot in terms of surface temperature compared to other types of stars. They are "dead" stars that have exhausted their nuclear fuel and are slowly cooling off over time.
How does the size temperature age and brightness of the sun compaare to other stars in the milky way galaxy?
our sun compared to other stars falls in the category of pretty average because our sun isn't to small or to big which helps support life on earth, itis also yellow which isn't veryhot because the hottest stars are blue or white. our sun is also in its main sequence ( like 90% of the rest of the stars
What is the stars intrinsic brightness called?
The intrinsic brightness of a star is called its absolute magnitude. This is a measure of how bright a star would appear if it were located at a standard distance of 10 parsecs (32.6 light-years) from Earth.
How are stars ranked according to temperature and brightness?
To do so, astronomers calculate the brightness of stars as they would appear if it were 32.6 light-years, or 10 parsecs from Earth. Another measure of brightness is luminosity, which is the power of a star - the amount of energy (light) that a star emits from its surface.
What can the maximum brightness of a supernova be compared to what?
There aren't really any comparisons to be made to a supernova. Let's try one; a supernova is as much brighter than the Sun is as the Sun is to a flashlight. A supernova will release as much energy in an hour as a regular star does in its entire 10-billion year life.
Is the sun the smallest star compared to others?
No. But the sun is one of the smaller types of star called 'yellow dwarf''. There are smaller and bigger stars also.
What the measure of a stars brightness called?
The measure of a star's brightness is its magnitude. A star's brightness as it appears from Earth is called its Apparent Magnitude.Star's brightness is measured by there magnitude.
Why do the brightest stars in your sky appear so bright compared to other stars in your sky?
The brightest stars appear brighter because they are closer to Earth or intrinsically brighter due to their size, temperature, or luminosity compared to other stars. Their brightness makes them stand out more in the night sky.
Stars that can change their brightness?
the moon can vary its brightness and the pink elephant called aphadophalis
Why does the sun appear larger than other stars in the sky?
The sun appears larger than other stars in the sky because it is much closer to Earth than those stars. This proximity makes the sun's size and brightness more prominent in our view compared to the distant stars.
When compared to other stars red giant stars are what?
When compared to the other stars, the Red Giant Star are very minute. There are other stars that are very large by far as compared to the Red giant stars.
What is the unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
What is the standard unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
What stars level of brightness as viewed by the unaided eye is called?
Apparent magnitude.
What is a stars level of brightness as viewed by the unaided eye called?
Apparent magnitude.
Do stars have the same brightness and sizes?
No. Stars vary greatly in size and brightness.
Is the brightness of a star compared to other stars called its magnitude.?
No; the "magnitude" is how bright the star is. It can either mean:* The apparent magnitude = how bright it seems to us, * The absolute magnitude = how bright the star really is (i.e., how bright it would seem at a standard distance).
