Going to the Moon

It's up in the sky every night but how much do we really know about our little orbiting pal?  Here are some quick facts about the moon.  Next time you are out at night be sure to give the globe in the sky a closer look.

  • The average orbiting speed of the moon is .63 miles per second
  • The moon has only 16% of the gravitational pull as the Earth
  • The moon is thought to have been formed when a Mars sized lump of rock hit the Earth 4.5 billion years ago
  • Mainly, only one side of the moon ever faces the earth
  • There are traces of helium, neon, hydrogen and argon in the Moon's atmosphere.
  • The average surface temperature of the moon is -9.4 degrees Fahrenheit
