Earth and Space

Rotation

• A rocky object that orbits a planet; a natural satellite.

• The spinning of Earth on its axis

• any of numerous small celestial bodies composed of rock and metal that move around the sun (mainly between the orbits of Mars and Jupiter)

• The name of our galaxy

Revolution

• Gigantic spheres of burning gas like our sun but these are very far away!

• Pluto

• Earth's revolution takes this long

• The movement of an object around another object

sun

• A meteoroid that has hit earth's surface.

• The sun and moon appear to move across the sky

• The star at the center of our solar system

• Earth's rotation takes about

asteroid

• The movement of an object around another object

comet

• A loose collection of ice and dust that orbits the sun, typically in a long, narrow orbit.

• a relatively small, rocky body that travels through space

• Earth's rotation on its axis

meteor

• A force of attraction between objects that is due to their masses.
