THE EARTH, THE MOON AND THE SUN







THE EARTH


The EarthDuring the day earth receives light from The Sun directly and at night the light of the sun is directed towards The Earth through The Moon.  Earth interacts with other objects in space, especially the Sun and the Moon. During one orbit around the sun, the Earth rotates about its own axis 366.26 times, creating 365.26 solar days, or one sidereal year. The Earth's axis of rotation is tilted 23.4° away from the perpendicular of its orbital plane, producing seasonal variations on the planet's surface with a period of one tropical year (365.24 solar days).













THE MOON

The MoonWe see the Moon because of sunlight that is reflected by it.  It is the brightest object in the sky after the Sun, although its surface is actually very dark. The Moon's current orbital distance, about thirty times the diameter of the Earth, causes it to appear almost the same size in the sky as the Sun.













THE SUN

The Sun.   It  has “burned” for more than 4.5 billion years. It warms our planet every day and provides the light by which we see all the beautiful things around us. Sunlight is necessary for life on Earth.  The Sun is currently traveling through the Local Interstellar Cloud in the Local Bubble zone, within the inner rim of the Orion Arm of the Milky Way galaxy. The Sun orbits the center of the Milky Way at a distance of approximately 24000-26000 light-years from the galactic center, completing one clockwise orbit, as viewed from the galactic north pole, in about 225–250 million years.








EXTRA INFORMATION FOR THE EARTH, 

THE MOON AND THE SUN

















PHASES OF THE MOON



  • The New moon is when the moon is all dark. None of the moon that we can see is lit up during the new moon.
  • Crescent moon is when the moon is between the new and quarter moon stages. It looks like a "C" shape.
  • The Quarter moon is when half of the moon is visible. If the moon is waxing, it is called the first quarter, if the moon is waning, it is the last quarter
  • Gibbous moon is between the quarter and full moon stages. More than half of the moon can be seen, but not all of it.
  • The Full moon is when the moon is all lit up. All of the moon that we can see is lit up by the Sun during the full moon.
  • A second full moon in one calendar month is usually called a blue moon. The saying "Once in a blue moon" refers to something that does not happen often - like a blue moon.
