Question

which is the king planet of solar system why

Answer 1

Yo!
Here's your answer,bud,
Jupiter is the largest planet in our solar system. This gargantuan object dwarfs the earth—indeed, over 1,300 Earth-sized objects could fit inside Jupiter. And its mass is 2.5 times that of all the other planets combined.That's why it is called the "king" of all the planets in the Solar System.
I hope that this helps ya!
