Our Sun is 150,000,000 km (93,000,000 miles) away from Earth. Seems like a lot, right?


The Sun is down right close compared to other objects in space. Even the Andromeda Galaxy, our closest large neighbor, is a whopping 15,000,000,000,000,000,000 miles away. That’s 15 quintillion miles!

To cope with these unimaginably long distances, astronomers use other measurements — like AUs and light years — in their studies. If you want to learn how this all works, take a look at this video made by Astronomy Magazine:
