Science Solar System

• a real or imaginary line that a spinning object turns around
• (ex. Earth's north and south pole)

when the part of the Moon you see gets smaller (slowly goes away)

to show or compare one thing to another

to spin in place (ex. earth takes 24 hours to cause day and night)

a flattend circle shape (ex. the orbit of Earth)

a hollow area, or pit, in the ground

the path a revolving object moves along

the move in a circular or nearly circular path

different shapes of the Moon

when the part of the Moon you see grows larger (gets shinier like when you wax a car)

a hot, glowing sphere of gases that gives off energy

an area between the inner and outer planets

made up of the sun, 8 planets, moons, and other objects in space

an object that moves in orbit around another, larger object

(God-made = moons Man-made = metal ones)

chunks of rock or metal that orbit the sun

a pattern or picture outlined by stars; used by farmers for planting and sailors for direction

mostly chunks of ice mixed with bits of rock and dust; tails are formed as the sun melts part of it (ex. Halley's)

small pieces of ice, rock or metal that have broken off colliding comets or asteroids

a meteor that gets through Earth's atmosphere

sphere shaped satellites of the sun; they cannot make their own light
