In our solar system , we have many dwarf planets.
I am talking about a celestial body which was once called planet but now it is a dwarf planet.
It is none other than Pluto !!!
Though Pluto is a dwarf planet, it has 5 moons !!!
Largest of them is Charon.
The same surfaces of Pluto and Charon always face each other.
This is called mutual tidal locking.
These two are the double dwarf planets.
