* Massive Stars: These stars (8 or more times the mass of our Sun) burn through their fuel quickly and have a relatively short lifespan, lasting only a few million years.
* Medium-Sized Stars: Our Sun is an example of a medium-sized star, and they have lifespans of around 10 billion years.
* Small Stars (Red Dwarfs): These stars are much smaller and cooler than our Sun, and they burn their fuel extremely slowly. Their lifespans can reach trillions of years, far exceeding the current age of the universe.
Here's a simplified way to think about it:
* Bigger stars = shorter lives
* Smaller stars = longer lives
Important Note: These are just general estimates. The exact lifespan of a star can also be influenced by other factors, such as its chemical composition and the presence of other stars nearby.
