what is the surface of the moon made of
The Moon is an astronomical body orbiting Earth as its only natural satellite. There are also trace elements like titanium, uranium, thorium, potassium and hydrogen.Want to compare the Moon to other objects in the Solar System? Earth and the moon aren't made of exactly the same stuff. When exposed to solar radiation, water quickly decomposes through a process known as In years since, signatures of water have been found to exist on the lunar surface.Analysis of the findings of the Moon Mineralogy Mapper (M3) revealed in August 2018 for the first time "definitive evidence" for water-ice on the lunar surface.The Moon makes a complete orbit around Earth with respect to the fixed stars about once every 27.3 daysThe Moon is an exceptionally large natural satellite relative to Earth: Its diameter is more than a quarter and its mass is 1/81 of Earth's.The Earth revolves around the Earth-Moon barycentre once a sidereal month, with 1/81 the speed of the Moon, or about 12.5 metres (41 ft) per second. It suggests that instead of being spun out of the Earth, the material that would become the Moon was instead ejected from the Earth during a massive impact.An object roughly the size of Mars, which planetary scientists have called Theia, is thought to have collided with the infant Earth early in its evolution (which is why we don't see much evidence of the impact in our terrain). Don't come to our conference unless you have something to say about the Moon's birth."

Or, at least, not fast enough to hurl a baby Moon out to space. People have also questioned what makes up our Children's fairytales tell us that the moon is made of cheese, but like all bodies in the solar system, rock is the more realistic ingredient. Earth and the moon aren't made of exactly the same stuff. In the case of the Moon, further studies of rocks from various places on and beneath the surface will help fill in the tale of our neighbor satellite's formation and evolution.The Sun and planets formed in a cloud of gas and dust called a protoplanetary disk some 4.5 billion years ago. This would have melted the outer shell of Earth, and thus formed a magma ocean.While the giant impact hypothesis might explain many lines of evidence, some questions are still unresolved, most of which involve the Moon's composition.In 2001, a team at the Carnegie Institute of Washington reported the most precise measurement of the Crystallization of this magma ocean would have created a Consistent with this perspective, geochemical mapping made from orbit suggests the crust of mostly The Moon is the second-densest satellite in the Solar System, after The dark and relatively featureless lunar plains, clearly seen with the naked eye, are called Almost all maria are on the near side of the Moon, and cover 31% of the surface of the near side,The lighter-colored regions of the Moon are called The concentration of maria on the Near Side likely reflects the substantially thicker crust of the highlands of the Far Side, which may have formed in a slow-velocity impact of a second moon of Earth a few tens of millions of years after their formation.The other major geologic process that has affected the Moon's surface is Comparison of high-resolution images obtained by the Lunar Reconnaissance Orbiter has shown a contemporary crater-production rate significantly higher than previously estimated. This results in elevated sea levels called While gravitation causes acceleration and movement of the Earth's fluid oceans, gravitational coupling between the Moon and Earth's solid body is mostly elastic and plastic. China has landed two rovers on the surface, including the first-ever landing on Moon's far side in 2019. Here on Earth, erosion can alter and cover formations over time. Here is a table from Wikipedia (Moon - Wikipedia) giving the chemical composition of the lunar crust. The crust, the Moon’s outer shell, is covered by lunar soil, also called regolith: a blanket of fine rock particles, varying between three and 20 metres (10–65 feet) deep. The composition of the Moon is a bit of a mystery. This motion is superimposed on the much larger revolution of the Earth around the Sun at a speed of about 30 kilometres (19 mi) per second. Larger planets tend to have more satellites, both large and small, than smaller planets.Brooks, A.S. and Smith, C.C.
