‘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%!
On Thursday, July 1, scientist Jonathan Cirtain from NASA’s Marshall Space Flight Center will answer your questions about our fascinating solar system. Joining the chat is easy. Simply visit this page on Thursday, July 1 from 3-4 p.m. EDT. The chat window will open at the bottom of this page starting at 2:30 p.m. EDT. You can log in and be ready to ask questions at 3:00.
