We are tiny creatures on a small world, orbiting one ordinary star in an enormous universe. 🌌

And yet, from this little planet, we’ve managed to uncover the laws governing atoms, understand how stars and galaxies evolve, and send robotic spacecraft into interstellar space.

🚀 We’ve looked billions of years into the cosmic past, measured worlds around other stars, and learned that the elements in our bodies were forged by ancient stars.

✨ The universe is unimaginably vast—and somehow, a species on one small planet has learned to understand a piece of it.

Maybe that’s one of the most remarkable things about being human.

What do you think is the greatest discovery humanity has ever made about the universe?

The Sun contains about 99.86% of the total mass of the Solar System, making it overwhelmingly the most massive object in our planetary neighborhood. NASA estimates that the Sun alone accounts for essentially all of the mass, while every planet, moon, asteroid, comet, and other smaller body together make up only about 0.14%.

🪐 Jupiter is the most massive planet, with a mass about 318 times that of Earth. Its share of the Solar System’s total mass is roughly 0.095%, commonly rounded to 0.10%.

🌍 Earth is tiny by comparison. Its mass is about 1/318 that of Jupiter and only around 0.0003% of the Solar System’s total mass.

🔭 This enormous concentration of mass is why the Sun dominates the Solar System’s gravitational structure. Its gravity keeps the planets, dwarf planets, asteroids, comets, and other objects in orbit around it.
