Interesting facts about the moon  
  • Rotation of moon
    The same side of the Moon always faces the Earth. The Moon's rotation period is synchronous with its revolution period around the Earth.
     
  • Change of distance
    Because of a loss of orbital energy to gravity from the Earth, the Moon is very gradually moving away from the Earth. In the very early history of the Earth, the Moon looked about 3 times larger in apparent size in the sky, because it was closer to the Earth.
     
  • Lunar atmosphere
    The Moon has almost no atmosphere, because of its weak gravity. All types of gas will escape from its surface.
    Without an atmosphere, there is no wind or water erosion. The Moon's surface is about the same now as it was 3 billion years ago. The astronauts' footprints remain unchanged on the Moon's surface. The footprints should last at least 10 million years.
     
  • Temperatures on the moon
    The surface temperature fluctuates from roughly +300? F during the 2-week daytime to -270 F during the 2-week night. This is because there is not enough atmosphere to keep the Moon warm at night, nor protect it from the Sun's rays in the daytime.
     
  • The Apollo 11 mission to the moon
    Just twenty seconds' worth of fuel remained when Apollo 11's lunar module landed on the moon.
    The multi-layered space suit worn by astronauts on the Apollo moon landings weighed 180 pounds on Earth and 30 pounds on the Moon with the reduced lunar gravity.
    The average desktop computer contains 5-10 times more computing power than was used to land a man on the moon.

    The surface speed record on the Moon is 10.56 miles per hour. It was set in an Apollo lunar rover.
     
  • Size comparison
    The volume of the Earth's moon is the same as the volume of the Pacific Ocean.
     
  • Lunar magnetic field
    The Moon has no global magnetic field. You cannot use a compass to find your direction.
     
  • Strange Mathematics: 1/2 equals 1/4
    A quarter moon and a half moon are the same thing. The quarter refers to the fraction of the lunar month which has passed, whilst the half describes the portion of the Moon's disc which is visible.
     
  • Calculation of the Easter date
    Easter is the first Sunday after the first Saturday after the first full moon after the equinox. (The equinox is quite often March 21, but can also occur on the March 20 or 22.)
     
  • Tides and the moon
    The moon causes many of the tides in the Earth's oceans. This is because of the gravity force between the Earth and Moon. At full Moon and new Moon, the Sun, Earth and Moon are lined up, producing the higher than normal tides (called spring tides, for the way they spring up). When the Moon is at first or last quarter, smaller neap tides form.
     
  • Sun and Moon Eclipses
    An eclipse of the Sun can occur only at New Moon, while an eclipse of the Moon can occur only at Full Moon.

 

 

  • Moon Ingredients
    The moon is not made of cheese.

¤ This is by far the very best screen saver one can find. Lost hard drives etc....I will reinstall each and every time. Have had since 98 and wouldn't change it for one second. Who can ask for more than the 'moon and stars'?

? I am into Computers for almost 10 years now. I have seen all kinds of programs. But your little program here is so nice and so beautiful, I have never experienced something like this before. Your lullaby-music is so tender and caring, giving peace and rest. I would like to thank you very much for this little helper, you have given me so much peace and comfort.
