- Thanks for your question about the moon. As far as we know, from the moon missions and from very special meteorites that are actually pieces of the moon that have fallen to Earth, the moon is made up mostly of four minerals: plagioclase, pyroxene, olivine and ilmenite.

Moon The Moon is thought to have formed about 4.51 billion years ago, not long after Earth. There are several hypotheses for its origin; the most widely accepted explanation is that the Moon formed from the debris left over after a giant impact between Earth and a Mars-sized body called Theia.

Where Does the Moon Come From? Earth smashed into Planet Theia. Known as the giant impact hypothesis, the reigning lunar origin theory holds that the moon formed when Earth collided with a planet half its size—roughly as big as Mars—some 4.5 billion years ago.arth ensnared a drifting moon. According to the capture theory, the moon formed elsewhere in the solar system and happened to hurtle past Earth at just the right moment. As a result, Earth’s gravitational field “captured” the moon and brought it into orbit.

- play The Moon's birth. A possible explanation of the Moon's origin emerges. In the early 1970s, Dr William K Hartmann proposed that the early Earth collided with a planet the size of Mars, sending debris into the battered Earth's orbit. He theorised that the Moon formed from this debris. This clip refers to the Moon as being dry.

- The moon was formed ~4.5 billion years ago, about 30–50 million years after the origin of the Solar System, out of debris thrown into orbit by a massive collision between a smaller proto-Earth and another planetoid, about the size of Mars.

What is the Moon Made Of? The surface of the moon. 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. The moon's surface is covered with dead volcanoes, impact craters, and lava flows, some visible to the unaided stargazer.

- Moonquakes of very low energy are caused by land tides produced by the pull of Earth's gravity, and, from analysis of moonquake data, scientists believe the Moon has two layers: a crust, from the surface to 65 kilometers depth, and an inner, more dense mantle from the crust to the center at 3,700 kilometers.

Moons Other moons are asteroids captured into orbit by a larger body's gravity. Only the dwarf planet Pluto's moon Charon is thought to have formed from a collision like the one that gave rise to Earth's moon. No matter how they form, the moons are many. Only Mercury and Venus are moonless. Earth has one, Mars two. Neptune has 13 and Uranus 27. The gas giant Jupiter has 63 known moons. Saturn has at least 60—and 42 of those have been discovered since 1997.

How did the Earth form? The moon, the main satellite of the Earth is believed to have formed about 4.5 billion years ago when an object that roughly was the size of Mars collided with the Earth causing a significant blow to the Earth.

- One of the biggest misconceptions about the Moon is that its phases are caused by the Earth's shadow. The Earth's shadow causes eclipses, but it has nothing to do with phases.Rather, the phases of the Moon are produced by the alignment of the Moon and the Sun in the sky.ne of the biggest misconceptions about the Moon is that its phases are caused by the Earth's shadow.

What makes the harvest moon orange? Confidence votes 188. It is caused when the sunlight the moon is reflecting passes so close earth that it actually passes through earths atmosphere were blue get absorbed, reflected, and/or bent and a orangish-red light is what makes it through this is caused by wave differentiation of light. The orangish-red light then reflects back off the moon.

Moon The Moon's gravitational influence produces the ocean tides, body tides, and the slight lengthening of the day. The Moon's current orbital distance is about thirty times the diameter of Earth, causing it to have an apparent size in the sky almost the same as that of the Sun.This allows the Moon to cover the Sun nearly precisely in total solar eclipse. This matching of apparent visual size is a coincidence.he principal modern English adjective pertaining to the Moon is lunar, derived from the Latin Luna. A less common adjective is selenic, derived from the Ancient Greek Selene (σελήνη), from which the prefix seleno- (as in selenography) is derived.

Phases of The moon The moon's phases are caused by the changing angles of the earth's shadows and reflected sunlight as the moon revolves around the Earth over the course of about 1 month (28 days). An imaginary line where the Earth is tilted. The earth completes one revolution around the sun every 365 days.

Lunar Geology Lunar Geology. Dark regions on the Moon are called maria, which is Latin for seas. So Mare Tranquilatis is the Sea of Tranquility. Apollo astronauts discovered that these regions are smooth, low-lying plains with relatively few craters. Maria get their color from a type of rock (called basalts) similar to the dark colored rocks formed by lava from volcanoes here on Earth. Basalts are composed of relatively heavy elements such as iron, manganese, and titanium. Tests showed these lunar rocks are between 3.1 and 3.8 billion years old.

About the Moon Earth's moon has a core, mantle and crust. The moon’s core is proportionally smaller than other terrestrial bodies' cores. The solid, iron-rich inner core is 149 miles (240 kilometers) in radius. It is surrounded by a liquid iron shell 56 miles (90 kilometers) thick.

What Color is the Moon? The photographs of the Moon, taken from space are the best true-color views of the Moon. That gray color you see comes from the surface of the Moon which is mostly oxygen, silicon, magnesium, iron, calcium and aluminum.

What causes the craters on the moon? The face of the moon is pitted with some 300,000 craters more than a mile wide, plus countless smaller ones. Surely so many meteors could not hit the moon and miss the earth, On earth, most volcanic craters are on the tops of mountains, The moon has a few such craters, but most of them are pits below the level of the surrounding landscape,

What is the grace period for an expired California driver's license? In California there is no grace period for an expired driver's license. You must apply for a renewal of your driver's license at least 60 days before it expires because the DMV will take 60 days to mail you the new license. You cannot drive a vehicle if your driver's license has expired. You can apply for a new one if it has expired.

Where did the Moon come from? One idea put forward was accretion theory. This posits that the Earth and Moon formed together from a giant spinning disk of matter, which surrounded a black hole. This theory died a quick death. It couldn't explain the speed with which the Moon orbits the Earth.

Where did the Moon come from? The chemist Harold Urey proposed instead that the Moon came from another part of the galaxy, and was pulled in by the Earth's gravity as it passed by. The capture theory gets a lot right. The Moon is large compared to the Earth, unusually so for a satellite, but if it formed elsewhere that suddenly makes sense.

What Makes the Moon Look Orange? For example, sometimes the Moon appears white, while at other times it's more yellow or even orange. If it was made of cheese, you could explain these different colors by types of cheese: mozzarella for white, American for yellow, and cheddar for orange! Rest assured. The Moon is NOT made of cheese.

The day the earth exploded: Scientist claims moon was created by massive nuclear blast which tore apart our planet four billion years ago A Dutch scientist has claimed that the moon was created by massive nuclear blast which tore apart our planet four billion years ago. The scientist, from VU University in Amsterdam, told New Scientist magazine that previous explanations about how the moon came to be simply do not add up.

What Do Crabs Eat in the Ocean? The crabs live up to 20 years with only the male crabs caught for commercial use. Snow crabs feed on bottom-dwelling sea life, including bivalves, brittle stars and crustaceans, including their own species. They also eat worms, gastropods and several varieties of small fish.

Universe Today Space and astronomy news Size, Mass and Orbit: With a mean radius of 1737 km and a mass of 7.3477 x 10²² kg, the Moon is 0.273 times the size of Earth and 0.0123 as massive. Its size, relative to Earth, makes it quite large for a satellite – second only to Charon‘s size relative to Pluto.
