  • 1. Comets, Asteroids, Meteors, and Moons By: Alex Rogowski
  • 2. Comets
    • Comets are Small, balls of ice, gas, and dust that orbit around the Sun.
    • Comets are made up of four parts the Nucleus, the Coma, the Hydrogen Envelope, and the tail.
  • 3. Asteroids
    • Large remains of rocks left from the formation of the Solar system
    • Orbit around the sun
    • Most asteroids are found in the Asteroid belt between Mars and Jupiter.
  • 4. Asteroids
    • Asteroids are not considered planets, but can have moons.
    • One Example of this is the asteroid Ida and its moon Dactyl.
  • 5. The Moon
    • Earth Has one Moon that is believed to have been created from an impact with an asteroid
    • The average distance between the Earth and Moon is 238,855 miles(384,400 Km)
  • 6. Phases of The Moon
    • The Moon has eight phases that it goes through
    • The first phase of the moon is the New Moon, this occurs when the moon is between the earth and the sun
  • 7. Phases of The Moon
    • The Gibbous occur when the sunlight is slightly more than half or slightly less than half
    • The Quarter phases happen when the Moon is in line that the sun only reflect off half of the moon
  • 8. Phases of The Moon
    • Lastly there is the Full Moon, this occurs when the Sun, the Earth, and the Moon are in perfect alignment giving it its fully illuminated glow
  • 9. The Moons Orbit
    • The Moon Revolves Around the Earth Once a month
    • The Moons orbit effect the tides in oceans and the motion and orbit of the earth.
  • 10. What If the Earth had Two Moons?
    • The Tides would be effected and it would cause constant Tsunamis and flooding
    • Also I believe it would effect the orbit of earth and possibly changing the seasons
