2. Asteroids
● These are the rocky and airless leftovers from
the formation of planets in our solar system.
● They mostly orbit our sun in the asteroid belt
between Mars and Jupiter and range from
the size of cars to dwarf planets.

5. Comets
● Comets are dirty space snowballs of mostly
ice and dust that formed during the birth of
the solar system 4.6 billion years ago.
● Most comets have stable orbits in the outer
reaches of the solar system past the planet
Neptune.

8. Meteors
● Meteoroids are tiny asteroids or the broken-off
crumbs of comets and sometimes planets. They
range in size from a grain of sand to boulders 3 feet
(1 meter) wide.
● When meteoroids collide with a planet's atmosphere,
they become meteors.
● If those meteors survive the atmosphere and hit the
planet's surface, their remains are called meteorites.
