Why do stars have different brightness?
When we look up at the starry sky, we will discover that, among countless stars, there is a light, a dark one, their brightness is very different.
Explain the cause of glowing stars
There are two factors that determine how bright the stars are, both to see how strong their luminescence is, to see how far they are from the Earth .
Astronomers have divided the luminescence capacity of stars into 25 stellar states, the luminescence power is 10 billion times stronger than the weakest luminescent capacity. However, no matter how powerful a star has a luminescence capacity, if it is too far away from Earth, its brightness is not equal to that of stars with poor luminescence.
For example, there is a planet named Tu Tu Nhi , 220 million times more massive than the Sun , its luminous capacity is about 50,000 times higher than the Sun, but about 410 light-years from Earth, because The distance is too great, so when you look at it, it is just a star flashing red light. But if the star Tu Tu Nhi is transferred to the position of the Sun, all things on earth will be destroyed by it.
