The Sun Owns 99.86% of the Solar System's Mass
Imagine the entire Solar System as a huge cake. If you were to cut that cake, the Sun would take the whole thing, leaving only a tiny crumb for everyone else. That is how heavy the Sun really is!
A Giant Among Tiny Marbles
The Sun holds 99.86% of the total mass of our Solar System. This means that if you put the Sun on one side of a giant scale and all the planets (like Jupiter and Earth), all the moons, all the asteroids, and all the comets on the other side, the Sun would barely move. The rest of the Solar System - including us - makes up only 0.14% of the weight!
Jupiter and the Others
Out of that tiny 0.14% left over, the giant planet Jupiter takes most of it. If you don't count the Sun, Jupiter is twice as heavy as all the other planets combined. This makes Earth look like a tiny speck of dust compared to the Sun. In fact, you could fit about 1.3 million Earths inside the Sun!
Why This Matters
Because the Sun is so heavy, it has a super strong pull called gravity. This gravity is like an invisible leash that keeps all the planets from floating away into deep space. It holds everything together in a perfect circle, making sure the Earth stays exactly where it needs to be for us to live.
In Short
The Sun is the undisputed heavyweight champion. It contains 99.86% of all the matter in our Solar System. Everything else - from the biggest planet to the smallest grain of sand in space - is just a tiny bit of leftover material spinning around a giant star.
