Moon Facts

  • Moon


    After the sun the moon is the second brightest object in the sky, it orbits the Earth once every month. As it orbits we can see the different changes known as phases, this is caused by the alignment on the sun and moon, as the moon orbits the Earth we can see the bright parts lit up by the reflection of the sun at different angles. There are eight different phases, new moon, waxing crescent, first quarter, waxing gibbous, full, waning gibbous, last quarter and waning crescent.  The moon orbits near the equator so people in the northern hemisphere will see a different angle (upside down) than those in the southern hemisphere. The moon is in synchronous rotation with Earth so this means the same side of the moon always faces Earth.

    The Moon effects the tides on Earth, tides are the rise and fall of our sea levels, these are affected by the gravitational pull of the moon, the sun and the rotation of Earth.




    An eclipse is when the moon, sun or Earth line up with each other and one of them block the light from another. There are two different types of eclipse, solar and lunar. A solar eclipse is when the moon moves between the sun and Earth blocking the sun from us where as a lunar eclipse is when the Earth blocks the suns light from hitting the moon making it dark.
