Definition 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. Keep Going

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. Keep Going

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. Keep Going

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 earth everyday, some are too small to cause any harm. Go back to Sub-menu

Asteroid 1 Definition Composition Interesting Facts 2 3

Click here to KEEP GOING 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

Click here to KEEP GOING Composition 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 Click here to KEEP GOING

Read this passage and see who discovered the FIRST asteroid!!! 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!!! Record voice saying what was the name of the finder, name of the asteroid , and where is it located

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

Comet Definition Composition Interesting Fact 1 2 3

Definition 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 on

Composition 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 carbon-based or organic compounds. Click here to go on

Follow the link to discover what the different parts of a comet are FIRST Interesting Fact Comets 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 Click here to go on

Interesting Fact 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.

Meteor Test What are the three types of meteor? stony, iron, stony-iron ice, stone, metal What is a meteor called when it produces enough light to be seen from earth? shooting star fire ball Keep Going

Asteroid Test What are the three types of Asteroids? iron, gold, magnesium stone, iron-nickel, mixture of both What Asteroid was discovered on August 23, 2001? Halley’s Asteroid Asteroid 2001 KX76 Keep Going

Comet Test Comets have a nucleus. True False Comets are made up of ice, dust, and gas. Click here to Finish
