In order to understand how long an individual star will live, you need to take into account a large number of indicators. TO
According to science, the lifespan of a starlinked to two important points. This is the mass and speed of the star's consumption of energy (that is, nuclear fuel). It is also believed that the smaller the star, the longer it can live.
The largest stars die after a few million years. But stars like the Sun can survive for about 10 billion years.
If the star itself is young and if its massless than 1/10 of the mass of the Sun, then it can live several hundred billion years. And this is longer than the existence of the Universe: it is now – 13.7 billion years.
But at the same time to understand the age of a particular stardifficult. To do this, astronomers measure the mass, brightness of the star, the speed of its movement compared to other stars. After that, they recreate everything using computer simulations.
When we look at the night sky, we mostlywe see stars that have a greater mass than the Sun, and are brighter than it. Therefore, such stars quickly die. Many stars that are older than the Sun are not as bright, so they can only be seen through a telescope.
