* Light years measure distance, not time. A light year is the distance light travels in one year.

* The Sun is not a destination you travel to. The Sun is the star at the center of our solar system, and we are already orbiting it.

So, the answer is that you can't reach the Sun in "light years" because you're already within the solar system.

If you were to ask how far away the Sun is, the answer is about 93 million miles or 150 million kilometers. That's a very short distance compared to the vast distances measured in light years.
