^{Objects made of ice, gas and dust and orbit our sun are called:}

• Asteroids

• Comets

• Meteroids

• Meteors

One similarity between asteroids, comets and meteoroids is that they all:

• are made of rock

• come from the Asteroid Belt

• come from the Oort Cloud

• orbit the sun

Planets that have no solid surface and are made of gases such as hydrogen and helium are called:

• Gas Giants

• Terrestrial Planets

The outer four plants, which are larger and have rings are called:

• Gas Giants

• Terrestrial Planets

We often see these objects appear as "shooting stars" or streak of light in the sky. They are "smaller" pieces of rock that are burning in our atmosphere.
