Modern thought has it that a body about the size of Mars, and given the name of Theia, collided gently with the Earth, and the debris from the collision resulted in the formation of the Moon.
Thus much of its rocks are similar to those of Earth, but it is mineral deficient. Earth's core was likely not involved in the collision.
The Moon obviously has an uneven distribution of mass, and that is why the Moon presents one face to Earth all the time. It probably had significant spin at some time, but tidal drag with the Earth has canceled this out.
1 earth mass = 81.78 moon mass (rounded)
1 moon mass = 0.01223 earth mass = 1.223% of earth mass (rounded)
What else can I help you with?
Why moon has less g value then earth?
The moons gravity is less than that of the earth, since the earths mass is greater than the moons mass. Gravity is related to mass and distance from that mass. The greater the mass, the greater the gravitational field it has.
What is the solar system made of?
Mercury's mass = 3.30 x 1023kg or 0.055 x Earths Venus' mass = 4.87 x 1024kg or 0.815 x Earths Earth's mass = 5.97 x 1024kg or 1 x Earths Mars' mass = 6.42 x 1023kg or 0.1075 x Earths Jupiter's mass = 1.90 x 1027kg or 317.8 x Earths Saturn's mass = 5.69 x 1026kg or 95.152 x Earths Uranus' mass = 8.68 x 1025kg or 14.536 x Earths Neptune's mass = 1.02 x 1026kg or 17.147 x Earths
Which planet has a greater mass than the combined mass of all the remaining planets and their moons?

Jupiter has a greater mass than the combined mass of all the other planets and their moons in our solar system.
Which planet is most like earth in size and mass?
Venus is closest to the Earths size and mass - often referred to as Earths sister or twin planet. Venus' Mass is around 82% of Earths, while its diameter is a little smaller than Earths at around 95% of Earths diameter.

Are you closer to the earths core or moons surface when standing at sea level?
Earth's core
How would your weight change if you went from the Earth to the moon?
Your would weigh 1/6th as much as you do here on mother Earth. The how is our moons' mass, and therefore its' gravity, is about 1/6 as much as the Earths'. Its' gravity well is not as deep as the Earths.
What is responsible for the earths moons phases?
Controlling the earth's tides.
