The surface area of the Moon is 3.793 x 107 km2.
The moon has no atmosphere, therefore there is no liquid water or any climate to speak of. Its surface is rocky, filled with craters, mountains and valleys.
A report was released in September 2009, indicating that an Indian lunar exploration team had indeed found "large quantities of water" on the moon. Furthermore, data collected from the Chandrayaan-1 spacecraft also pointed to the strong possibility that water was still being formed on the moon. See the related link.

∙ 13y agoThe Size of the Moon is:-
The average diameter is 3,475 kilometers (2,159.3 miles)
The average radius is 1,737.10 km (1079.6 Miles)
The equatorial radius is 1,738.14 km (1,080.03 miles)
The polar radius is 1,735.97 km (1,078.68 miles)
A little more than a quarter of that of the Earth.
The polar diameter is 2157.36 miles
The equatorial circumference of 6786.03 miles
and angular diameter of 30 arc minutes 59.61 arc seconds.

It is divided into light areas called the Lunar Highlands and darker areas called Maria(literally, "seas"; the singular is Mare). The Maria are lower in altitude than the Highlands, but there is no water on the Moon so they are not literally seas (Recent evidence from the Clementine spacecraft suggests that there may be some water on the Moon, contrary to previous assumptions). The dark material filling the Maria is actually dark, solidified lava from earlier periods of Lunar volcanism. Both the Maria and the Highlands exhibit large craters that are the result of meteor impacts. There are many more such impact craters in the Highlands.

∙ 11y agoThere are two distinct landscapes on the Moon, these are the Highlands and the Maria.
The Maria consists of 20% of the Moons surface. They are the dark areas which were formed by lava flows millions of years ago. There is no longer any volcanic activity on the moon, so no more Maria terrains will be made.
Most of the rocks in Maria terrains are variations of Basalts.
The Highlands (also known as "Terrae") consists of 80% of the surface.
The Highlands are littered with craters, large and small, caused by meteoroid impacts. Most rocks found in the highlands are anorthosite rocks, which are mainly formed of calcium.
The Moon, mostly the Highlands, is layered with powdery, rocky soil, scattered with rocks, dust and globules. This loose layer is called Regolith.
These loose layers actually cause problems for Astronauts because it can clog space suits and equipment. If it is breathed through the lungs, it can cause silicosis (most likely to be breathed through the lungs on Earth, when samples are brought back for analysis, since it's impossible to breathe normally on the Moon).
It's not yet known what lies underneath the dusty Regolith layer. Removing the layers to analyse the solid surface of the Moon would be a daunting task, not just because the negative effects of the dust to suits and equipment, but because gravity will simply just refill the hole or cause hazardous dust to float around the excavation site.
There are also many natural mountains on the Moon, not just those caused by meteoroids.
Many of these mountains were also volcanoes. But the volcanic activity on the moon died out millions of years ago. Which also means no new mountains will be formed.
It has also been discovered that the surface of the moon contains ice. Mostly hidden in dark, cold craters where the sun cannot reach.
Believe it or not, you can actually get a look at the surface of the Moon yourself. No telescope needed. Thanks to a partnership between NASA and Google.

∙ 14y agoAlmost none. The force of gravity decreases by the square of the distance. The Earth's radius is about 4,000 miles. The Moon's surface is about 225,000 miles away, or about 58 times further. 58 squared is 3364, so the Earth's gravity at the Moon's surface is 1/3364th of the Earth's gravity at the surface of the Earth.

∙ 11y agothe surface of the moon is full of craters it is rough though when an astronaut sets step on the moon he doesnt feel any of the roughness or does not fall into any crater .

∙ 13y agook in my text book i have the exact same question and heres the awnser according to some research and my teacher: 1.61N. Hope that helps :D

Why is the gravitational field strength of earth and moon are different?
Mainly, the Earth and the Moon have different masses.
How does the gravitational pool of the moon compare to that of earth?
An object on the surface of the moon weighs about 1/6 as muchas it weighs on the surface of the Earth.
Is the moon too small to have a gravitational pull on another object?
No, the moon's gravitational pull on the earth is the dominate cause of tides in the oceans. When the Apollo moon missions were going on, the moon's gravity both kept the command module in orbit and the lander and astronauts on its surface. Nothing is too small to have a gravitational pull on another object.
What is believed to have happened to most of the Moon's volatile elements?
As the Moon has a relatively small gravitational field, lower density elements will escape into space.
The Moon has the gravity of the Earth?
The gravitational force of attraction between the moon and an objecton or near its surface is 0.165 of the force between the Earth and thesame object on or near Earth's surface.
Why there will be a point between the earth and the moon at which the gravitational field strength will be zero?
There is a point where the gravitational field strength of both planet or object is equal, hence they cancel off each other, resulting in zero net gravitational field strength.
Why is the gravitational field strength of earth and moon are different?
Mainly, the Earth and the Moon have different masses.
What is g on the moon?
The gravitational field at the Moon's surface is 1.622 meters/second square = 1.622 newton/kilogram. That is about 1/6 of Earth's gravitational field.
What is Moon's gravitational field strength?
I think it's 1.61 Newtons per kilogram,.
How much would a 10kg suitcase weigh on the surface of the moon?
16kg as Weight = Mass x Gravitational Field Strength therefore ? = 10 x 1.6, so its 16.
Which is stronger the gravity on earth or the moon?
The gravitational field strength (how strong gravity is) on the Earth is 6 times stronger than on the moon.
Why can you only see one side of the moon from the earths surface?
because of the earth and moon's magnetic field and gravitational pull
Why does earth excert o stronger gravitational force than the moon?
It exerts a stronger force on us (when we are on it's surface) for two reasons: 1. It has a larger mass (gravitational field strength increases with mass). 2. It is closer (gravitational force is inversely proportional to the square of the distance from the object's centre of gravity).
How do astronauts stay on the Moon's surface?
the moon's gravitational pull.
How mass and weight differs on the earth and the moon?
Mass is the same but weight is about six times less on the moon. This is because the gravitational field strength of the moon is about six times less than that of earth.
Why is the gravitational field strength on the moon less than on the earth?
The gravitational potential energy is [ m g h ]. m = the object's mass g = the acceleration of gravity where the object is h = the object's height above the surface 'm' and 'h' are the same on the moon, but 'g' on the moon is only about 0.16 of what it is on earth. So [ m g h ] is also only about 0.16 of what it is on earth.
What effect does distance have on the strength of a gravitational?
There are quiet a few factors that will affect the strength of gravitational force, mass or weight of two bodies and their distance.You can use this formula to calculate the force or gravitational strength in different circumstances, which was discovered by Isaac newton .M1is usually the bigger mass that has its own gravitational field like sun, earth or moon and the second m2 is usually the smaller mass compared to m1, like satellite revolving around a bigger mass.The strength is massively effected by an object's mass, like we can imagine the gravitational force when we do sky diving, we are just pulled towards the ground. But when a satellite is revolving above the surface of the earth the gravitational strength is not so great.
