Moon Facts

THE MOON IS EARTH'S CLOSEST NEIGHBOR IN SPACE, BUT IT IS STILL FAR AWAY. The Earth-moon distance is about 250,000 miles (actually 239,000 miles).


TRAVELING TO THE MOON BY CAR at 55 miles per hour for 12 hours a day would require one year’s worth of time to complete the trip. Of course, one would have to return which would require an identical amount of time. A student could miss two full years of school on a round trip to the moon.



IF AN ASTRONAUT, WHILE ON THE MOON, FILLED A BALLOON WITH HELIUM GAS, WOULD THE BALLOON RISE, FALL, OR STAY EXACTLY WHERE THE ASTRONAUT LEFT IT?

The balloon rises on Earth because it is lighter than the air. It will fall on the moon because there is no air on the moon, so the balloon cannot be lighter than the air.
