It's impossible to answer "how big are the little stars" without more context. Here's why:

* "Little" is subjective: What seems small to us might be huge compared to other objects in the universe.

* Stars come in different sizes: Stars vary greatly in size, from tiny red dwarfs to massive blue giants.

To answer your question, we need to know:

1. What type of stars are you referring to? Are you thinking of the faint stars we see in the night sky? Or are you thinking of stars in a specific category like red dwarfs or white dwarfs?

2. What are you comparing their size to? Are you curious about their diameter compared to our Sun? Or are you interested in their volume compared to other celestial bodies?

Here are some examples:

* The smallest stars: Red dwarfs are the smallest and coolest type of stars. They can be as small as 10% the size of our Sun.

* Our Sun: Our Sun is considered a medium-sized star.

* Giant stars: Red giants and blue giants are much larger than our Sun, some even hundreds of times bigger.

* Supergiants: These are the largest stars known, sometimes even thousands of times bigger than our Sun.
