Moon , Lunar Phases, Eclipses
Transcript of Moon , Lunar Phases, Eclipses
240,000 miles or 385,000 kilometers away from earth
Mass of the moon = 1/8 of the mass of the earth Moons in the Solar System There is a total of 166 moons in the solar system
Mercury and Venus are the only planets who doesn't have a moon
Earth has 1 moon
Mars = 2
Neptune = 13
Uranus = 27
Saturn = 60
Jupiter = 63
If pluto was still considered a planet there would be 196 plances; pluto has 3 Phases of the Moon results from moon changing position relative to earth = lunar phase
moon orbits earth = moon encounters earth = happens the phase change
amount of sunlight hitting the moon = changes earth's view of moon
One month = moon changes from a fully lit circle to a thin crescent and back to a circle Lunar & Solar Eclipses lunar eclipse = earth comes between sun and moon = shadow of earth falls on moon
solar eclipse = moon moves between earth and sun, covering the sun from people's eyes in parts of the earth

(don't forget to rotate it while walking). Earth & moon switch places Why does the ocean have waves? Time to Practice
