  1. First let make the distinction between weight and mass. Mass has to do with the amount of matter is in some object, and determines how hard it is to push something around. Weight is how big the force of gravity is that is acting on some object. An object has the same mass no-matter where it is, but its weight depends on being close to the earth or some other planet. For example, if you were out in space, far away from any planets, you would have no weight since there is no gravity, but your mass would still be the same as it is here on Earth.

    So, it makes more sense to talk about the mass of the moon than its weight. This mass is about 7.35x10^22 kg. Thats the number 735 followed by 20 zeros! This is pretty massive, about 1/80th the mass of the Earth.


  2. 81 billion tons

    you can see there also!

  3. Heavy.

  4. we would never know,we can't measure it in the universe cuz there's no gravity

  5. Here --- calculate it--

    and this:

  6. 7.35 x 10^22 kg

  7. The weight of an object on the moon's surface is about 1/6 that of the weight of the same object on the Earth's surface.  

    For example, a man weighing 180 pounds on Earth will weigh only 30 pounds on the moon.

  8. i dont know, but its lower than earth and the sun

  9. Zero. It's in freefall.

  10. this is a trick question right?  the weight of the moon is like zero, cause it's in a zero gravity area? or does this only apply to the things on it?  or, how does that work?  Luitenant Dan, I am not a very smart man.

  11. Whether people will admit it or not, Viola is right.  The moon is weightless because it's orbitting the Earth,  just like astronauts on the space shuttle are weightless.

  12. The mass is 7.3477×10^22 kg.  

    Mass isn't the same as weight though.  To find the weight, you have to figure out the gravitational force from the Earth, the Sun, and the galaxy and add them up by vector addition.  The weight changes over time because the vectors change direction.  You have to make classical approximations too, because weight isn't well defined in general relativity.
