Composition• 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.

Interesting Facts• 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.

Interesting Facts• When a meteor produces enough
light to cast a shadow on the earth it is called a fireball.• More than million meteorites fall to

Definition
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.Click here to KEEP GOING
CompositionAsteroids 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 apartClick here to KEEP GOING
Interesting facts• Majority of asteroids are grouped in
asteroid belt.• Asteroid belt: a loose grouping of many
asteroids positioned between the orbits of Mars and Jupiter.
• Range in size of dust particles to many miles across
Read this passage and see who discovered the FIRST asteroid!!!
Interesting facts• 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

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.Click here to go

CompositionComets 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 carbon-
based or organic compounds. Click here to go

Interesting FactComets can suddenly brighten or
fade from view in a matter of hours.
They can lose their tail or develop multiple tails.
They can split into two or more pieces

Interesting FactThe 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.
