Fact 1 :- Pluto is known as dwarf planet.
In the last blog I mentioned that pluto and other some planets named and considered as dwarf planet and not as a planet according to the definition of planet given by International Astronomical Union (IUA).
According to IUA definition of planet is :-
a) It is orbiting around the sun.
b) It must be big enough to have enough gravity to force it into a spherical shape.
c) It must be big enough that it’s gravity cleared away any other objects of similar size near its orbit around the sun.
Pluto follows point a and b but not c that’s why it is considered as dwarf planet and not as a planet.
I hope so that now it is cleared to you if you have any doubt regarding previous blog.
