White dwarf stars are hot , but not very bright, because they are so small.
An example is "Sirius B", the companion of "Sirius A", the brightest star in the sky.
A star is a ball of gas that is very hot and very bright.
Arcturus is the brightest star that can be seen during the summer. Vega is also visible during the summer and would also be very bright, but not as bright as Arcturus.
Venus is a planet. It is nearer to the sun than we are, and when we can see it, it looks like a very bright star.
For example, galaxies are very large, very massive, very bright, and (most of them) very far away from us.
Venus is sometimes called "the evening star", although it is a planet. This because it is very bright and always appears close to the Sun in the sky. So, sometimes it appears in the evening as the Sun sets, looking like a very bright star.
How bright a star appears depends on both its actual brightness and how far away it is. The farther away a star is, the dimmer it appears. A bright but very distant star many therefore appear dimmer than a less bright star that is closer to us.
Canopus is a very bright star. It is in the southern constellation of Carina.
Your not very bright are you
VERY hot and bright.
A star is a ball of gas that is very hot and very bright.
The brightness of a star depends on its temperature, size and distance from the earth. The measure of a star's brightness is called its magnitude. Bright stars are first magnitude stars. Second magnitude stars are dimmer. The larger the magnitude number, the dimmer is the star.The magnitude of stars may be apparent or absolute.
This could be a white dwarf. Its essentially a `dead star` as nuclear reactions no longer take place, but it remains very hot for millions of years from residue heat. They are very small though, compared with other stars or the size they used to be. If a hot bright star is very very far from earth then this also will appear dim from earth. It may have a low apparent magnitude (but a high absolute magnitude).
They are very brittle and they can get up to a very bright temperature
a star
We cannot say for certain, but it if was very bright and visible shortly before sunrise then it was probably not a star but the planet Venus.
Arcturus is the brightest star that can be seen during the summer. Vega is also visible during the summer and would also be very bright, but not as bright as Arcturus.
The 3 factors that affect a star's brightness as viewed from earth, are: The star's age, distance from earth, and actual magnitude (scale a star's brightness is measured in).
