| Mass (1024 kg) | 0.07346 | 0.0123 |
| Volume (1010 km3) | 2.1968 | 0.0203 |

Also to know is, can gravity be changed?
The only thing we know that affects a body’s gravity is the amount of mass it contains. So to change Earth’s gravity we would need to add or remove mass from our planet. But to make a noticeable change, we would need to move vast amounts of material. Another factor is the rate at which our planet rotates.
Similarly one may ask, is the moon a solid mass?
At the center is the Moon’s dense, metallic core. The core is largely composed of iron and some nickel. The inner core is a solid mass about 480 km in diameter. Surrounding the solid inner core is a fluid outer core, that brings the total diameter of the core to about 660 km.
Is the Moon older than Earth?
The moon, researchers now say, likely formed about 50 million years after the solar system did, which is much earlier than the previous estimate of 150 million years after solar-system formation.
Is there gravity in space?
Some people think that there is no gravity in space. In fact, a small amount of gravity can be found everywhere in space. Gravity is what holds the moon in orbit around Earth. Gravity causes Earth to orbit the sun.
What is the mass of moon Class 9?
The mass of the moon is 7.35×1022Kg. Thus, the value of g on moon is g=1.625 m/s2.

Why is the moon’s mass so small?
The diameter of the Moon is only about 1/4 the diameter of the Earth, so it might seem like the mass of the Moon is strangely low. And you would be right. The key is the Moon’s low density. It has a density of only 3.3 g/cm3.
