Asteroid Belt
Between Jupiter and
Mars
Might have become
planets if not for
Jupiter's gravity
Meteoroids, Meteors, Meteorites
Meteoroid: small
pieces of rock moving
through the solar
system
Meteor: Small piece
of rock as it passes
through the Earths
atmosphere
Meteorite: Rock that
did not burn up and
made it to Earth’s
surface.
