What does the temperature and brightness of star indicate?

Answer 1

Its temperature, its mass, and its luminosity.

Its size, nor distance have nothing to do with the colour of a star, bar maybe diffusion through additional materials when viewed from Earth.

Answer 2

Astronomers classify stars based on their age, color, and brightness. These characteristics help them identify and understand the different kind OS stars. A stars surface temperature determines the amount of visible light given off its brightness and the color we perceive the star to be.

Answer 3

Temperature indicates a star's size. Provided the star is on the main sequence (isn't going through a red giant phase or going nova) hotter stars are larger stars. The brightness, or magnitude, of the star is actually reliant on its temperature. Hotter stars have a higher (compared to less-hot stars) absolute magnitude - that is, the brightness as seen from an established distance - the benchmark being Earth's distance from the Sun. . As you move further from any light source, it will seem less and less bright, this is relative magnitude.

Answer 4

The color of a star is an indicator of its surface temperature. In order of increasing temperature the colors are: red, orange, yellow, white, blue.

Answer 5

the color of the star tells you where in the sky it belongs.

Answer 6

the star is so bright so thats why we can see it

Answer 7

Basically, at different surface temperatures, stars have different colors. For example, a blue star is hotter than a yellow star, which in turn is hotter than a red star.

Answer 8

It can give you a rough idea of the star's surface temperature.

Answer 9

It can tell you its temperature and composition.
