Every planet you know is a rounding error.
Every planet you know — every moon, every asteroid, every comet ever spotted — adds up to just 0.2% of our solar system's total mass. The other 99.8%? A single star.
The Sun is so dominant that Jupiter, the largest planet, is an afterthought by comparison. About 1.3 million Earths could fit inside the Sun by volume, and it burns through roughly 600 million tonnes of hydrogen every second just to keep its balance.
That colossal weight is also what keeps everything in line. The Sun's gravity reaches out across billions of kilometres and holds every orbit together — from Mercury skimming past at close range to distant icy objects barely crawling through the dark.
We don't orbit a star. We orbit almost everything there is.
