TIL: Moons Larger than planets

IMAGE SOURCE

Today I saw the article by @logic, https://steemit.com/til/@logic/today-i-learned-about-the-largest-known-lake
In his post he was talking about the largest lake. I replied asking about why the moon was only called a moon and not a planet since he did say it was larger than Mercury. His reply was that "Because it doesn't orbit the star but the planet." So I decided to see what a planet definition was and found on

That a planet must orbit the star and not another object. I did not realize that before, I just had assumed that it was based on the size of the object.

Thank you for reading. I hope you also learned something new as well.
