However, it's important to note:
* This is an estimate. Astronomers are constantly refining their measurements of the galaxy's size and our position within it.
* We're not at the exact center. Earth is located in one of the galaxy's spiral arms, about two-thirds of the way out from the center.
To give you a better sense of scale, a light-year is the distance light travels in one year. That's about 5.88 trillion miles (9.46 trillion kilometers). So, the distance to the galactic center is a truly mind-boggling number!
