Every planet you know is basically a rounding error.
Every planet you know — every moon, every asteroid, every comet ever charted — all of it together makes up just 0.2% of the solar system's mass. The Sun owns the other 99.8%. That's not a margin. That's almost everything. By volume, about 1.3 million Earths could fit inside it. And it isn't sitting still — every second, the Sun fuses around 600 million tonnes of hydrogen into helium. That constant burning is what generates the gravity keeping every planet locked in orbit. Without it, the solar system isn't a solar system. It's just scattered debris drifting through darkness. Eight planets, hundreds of moons, millions of smaller bodies — all of them circling one enormous object that barely notices they're there.
