These are the other members of the solar system
Asteroids, meteoroids, and comets
These are found in our solar system
Asteroids, meteoroids, and comets
What is the acronym for NASA?
National Aeronautics and Space Administration
These have an outer layer of ice surrounding their core material
Comets
The outer layer of ______ turns to gas as it nears the sun, creating the coma and the tail
Comet
It produces light in comets
Tail
It is the one to produce speed in comets
Coma
These have highly elliptical orbits, allowing them extended periods away from the sun
Comets
These are mostly irregularly-shaped chunks of rocks, with sizes ranging from a few tens of meters to hundreds of kilometers
Asteroids
Most asteroids come from the ________ ____
Asteroid belt
Another name for it is the Asteroid Belt
Solar Junkyard
Where is the Asteroid belt located?
Between Mars and Jupiter
They sometimes collide with each other, resulting in dents or them breaking off into smaller pieces
Asteroids
These are the so-called parents of meteors
Asteroids
These are meteoroids that burn up as they enter Earth’s atmosphere, producing a streak of light
Meteors
We often call these as shooting stars
Meteors
These are pieces that break off from asteroids or debris left behind by comets
Meteoroids

These are the three types of meteoroids
Stony, Rich in Iron, and magnetic
It is what we call meteors that shine brighter than Venus
Fireballs
These are meteors that follow a particular path through Earth’s atmosphere, then back out again
Grazing Fireballs
These are the amount of asteroids in the solar system

These are the amount of meteors that land on Earth’s surface every year
500
These are the amount of meteors that reach scientists every year
5-6

When are asteroids, meteoroids, and comets formed?
The same time as our solar system
_________ have minimal to no impact on Earth’s surface
Meteorites
Larger _________, can potentially have significant and drastic effects on Earth

When do meteor showers happen?
When meteors passes through a comet’s path with rich debris from its disintegration
It usually occurs every year
Meteor Showers
