* Sun: It takes light from the Sun approximately 8 minutes and 20 seconds to reach Earth.

* Stars: The time it takes light from stars to reach us depends on their distance. Here are some examples:

* Nearest star (Proxima Centauri): About 4.24 years

* Sirius (brightest star in the night sky): About 8.6 years

* Polaris (North Star): About 433 years

* Andromeda Galaxy (closest major galaxy): About 2.5 million years

Why does it take so long?

Light travels incredibly fast, at approximately 299,792 kilometers per second (186,282 miles per second). However, the vast distances involved in space mean that even light takes a significant amount of time to travel from distant objects to Earth.

Think of it this way: Imagine you're shining a flashlight across a large room. It takes a tiny fraction of a second for the light to reach the other side. Now imagine that room is the size of our solar system, or even larger – the distances become immense, and the time it takes for the light to travel increases drastically.
