‘Summer Science Camp’ Chat: Our Solar System REALLY Gets Around
The sun is the largest and most important object in our solar system, containing 99.8% of the solar system's mass, or quantity of matter. Among that remaining 0.2% are hot planets, icy moons, asteroid belts, chunks of rock, rings of ice, and over 100 worlds -- including our Earth. The "space" in between is a mesmerizing mix of the push-and-pull of gravity, solar winds, particle radiation, and magnetospheres. Not bad for a mere 0.2%!
