Other Celestial Objects

Comets

FOSS: Planetary Science pg. 51, 95-96

• Small, loosely packed body of ices, rock, and cosmic dust 

• Core is made of rocky metals, and water ice 

• Tails form when sunlight causes the comet’s solid ice to change into gas (sublimation) 

• Elongated orbits that come close to the Sun to well beyond Pluto. 

• Believed to originate in the Oort Cloud

Asteroids

FOSS: Planetary Science pg. 51, 91

• Small, rocky bodies that revolve around the sun

• Most are located in the asteroid belt between Mars and Jupiter

• Made up of different materials

• Carbon

• Stony or Metallic

• Rich in organic material

Meteoroids, Meteorites, and Meteors 

FOSS: Planetary Science pg. 71, 91

METEOROIDS:

They are dust and debris from comets and asteroids

Most are the size of sand grains, but some are much larger

Meteors: 

Meteoroids that burn up  when entering the Earth’s atmosphere

Meteorites: 

Meteoroids large enough to pass through Earth’s atmosphere and strike the ground

Lunar Phases

FOSS: Planetary Science pg. 44-45

1. Color in the different Moon Phases

2. Label all 8 phases of the moon 

3. Draw and color the Sun

4. Add the blue arrow showing the direction of the moon's orbit.

5. Define waxing and waning 

Waxing: getting bigger      Waning: getting smaller

Eclipses 

FOSS: Planetary Science pg. 45-48
Add bullet points describing both lunar and solar eclipses, label and color the diagrams 

Solar - (Sun, Moon, Earth = SME)

• Sun’s light is blocked by the moon, as it casts a shadow on Earth

Lunar - (Sun, Earth, Moon = SEM)

• Sun’s light is blocked by the Earth, as it casts a shadow on the Moon
