1. Understand the Units:

* Kilometers (km): A unit of distance in the metric system.

* Light-years (ly): The distance light travels in one year.

2. Key Conversion:

* One light-year is approximately equal to 9.461 trillion kilometers (9.461 x 10^12 km).

3. Calculation:

* Divide the distance in kilometers by the number of kilometers in a light-year:

33.11 trillion km / 9.461 trillion km/ly = 3.50 light-years (approximately)

Therefore, a star 33.11 trillion kilometers away is about 3.50 light-years away.
