Actually, our solar system is MOSTLY space,
with only a tiny
percentage of its volume taken up by matter like
the sun, planets, and
asteroids. The solar system is flying through
space at around 490,000
mph as it orbits the center of the Milky Way
light-years; or 162,000,000,000,000,000 miles
away). Our solar system
will probably be stuck in orbit around the
center of the galaxy
forever, due to the enormous gravity of the
galaxy. So, we don't have
to worry about being flung into intergalactic
space any time soon!
