a meteoroid that has entered the
earth's atmosphere; a fleeting fiery
streak in the sky produced by a
meteoroid passing through the
earth's atmosphere; a shooting star
or bolide.

• Stony meteors: made of rocks and
dust. The most common type.
• Iron meteors: made of iron.
• Stony-Iron meteors: made of rocks
and metals. The least common type.
Keep
Going
• Meteor Showers: multiple meteors
or meteorites swarm earth's
atmosphere and fall through the
atmosphere
• The meteor shower at the moment is
called Orionids it has been going on since
October 2 and it will end on November 7.
Keep
Going
• When a meteor produces enough
light to cast a shadow on the earth it
is called a fireball.
• More than million meteorites fall to
earth everyday, some are too small
to cause any harm.

Asteroid

a rocky object in space that can
be a few feet wide to several
hundred miles wide. Most
asteroids in the solar system
orbit in a belt between Mars
and Jupiter.

Asteroids are made of rock and metal; grouped
into three categories:
Stony: 92.8% are stony, and are made of Silicates
Iron-Nickel: 5.7% are iron-nickel
Mixture of the two: The balance are formed of
the mixture if iron-nickel and stone (silicate)
Also formed from other asteroids as they collide
and break apart

• Majority of asteroids are grouped in
asteroid belt.
• Asteroid belt: a loose grouping of many
asteroids positioned between the orbits of
Mars and Jupiter.
Read this passage and see who discovered the FIRST asteroid!!!
• Range in size of dust particles to many
miles across
• Several asteroids have been observed to
have moons of their own
• First to be observed with a moon was 243
IDA
• Asteroid 2001 KX76: discovered on August
23,2001 known to be the largest Asteroid in
the solar system
Comet

a small object made up of
ice, dust and gas that orbits
the sun. Jets of gas and dust
form long tails that can be
seen from Earth.

Comets are made mostly of ice (water
ice, as well as carbon dioxide, or "dry"
ice, and several other types), and rock.
The rock is in the form of small dust or
sand grains. In addition, comets
possess small amounts of carbonbased or organic compounds.

Comets can suddenly brighten or
fade from view in a matter of
hours.
They can lose their tail or develop
multiple tails.
They

The black crust of the nucleus helps
the comet absorb heat, which in turn
causes some of the ices under the
crust to turn to a gas.
The tails can be several million miles
long each, and the longest have been
observed to be over 93 million miles
long.
