How Does The Largest Star in the Universe – Size Comparison Work?

The largest star in the universe is so big it could swallow our whole solar system like a snack.

What Makes a Star Big?

Imagine you have a giant balloon, that's like a regular star. Now, picture a balloon the size of a football stadium, that’s Uyenshura, one of the largest known stars. It’s so big, if it were in our solar system, it would stretch from Earth to almost Mars!

How Big Is That?

Think about your favorite toy car, small and cute. Now imagine stacking 10 million of them on top of each other. That’s how wide Uyenshura is! If you put all the planets in our solar system next to it, they would look like tiny marbles.

Even though it's super big, Uyenshura isn’t that far away, just a little more than 4,500 light-years from us. That’s like having a giant friend who lives in another town, and you can still see them clearly through your telescope!
