The lifetimes of stars vary tremendously depending on their mass. Here's a general overview:

* Smallest Stars (Red Dwarfs): These stars have the longest lifespans, lasting trillions of years. They burn their fuel very slowly.

* Sun-like Stars (Yellow Dwarfs): Stars like our Sun have lifespans of about 10 billion years.

* Larger Stars (Blue Giants): These stars burn their fuel much faster and have much shorter lifespans, lasting only a few million years.

Here's a more detailed breakdown:

| Star Type | Mass (Solar Masses) | Lifetime (Years) |

|---|---|---|

| Red Dwarf | 0.08 - 0.5 | Trillions |

| Yellow Dwarf | 0.8 - 1.4 | 10 Billion |

| Orange Dwarf | 1.4 - 1.8 | 3 Billion |

| Red Giant | 1.8 - 2.5 | 1 Billion |

| Blue Giant | 2.5 - 8 | 10 Million - 100 Million |

| Supergiant | 8 - 20 | 1 Million - 10 Million |

| Hypergiant | >20 | < 1 Million |

Key Takeaways:

* Smaller Stars: Live much longer than larger stars.

* Larger Stars: Burn fuel rapidly and have short lifespans.

* Lifespan is inversely proportional to mass: The more massive a star is, the shorter its lifespan.

Remember, these are just general estimations. The actual lifespan of a star can be affected by various factors like its composition and rotation speed.
