It is composed of about ¾ hydrogen and ¼ helium, with a small percentage of other, heavier elements. On the outside is a rocky layer called the Earth's crust. The mantle is hot and represents about 68 percent of Earth’s mass. The earth’s distance from the sun is conducive to life. By atomic composition, the most abundant element found on the Moon is oxygen. Core, mantle, and crust are divisions based on composition. Earth's Moon is the only place beyond Earth where humans have set foot, so far.. Earth's only natural satellite is simply called "the Moon" because people didn't know other moons existed until Galileo Galilei discovered four moons orbiting Jupiter in 1610. Composition of the Earth The Earth is composed of a number of layers. Six of them landed astronauts safely on the surface, the only times humans have visited another world. The core makes up about 31% of the Earth. Deep in its core, the sun is extremely dense and hot, with temperature reaching over 15 million degrees Kelvin. It composes 60% of the Moon's crust by weight, followed by 16-17% silicon, 6-10% aluminum, 4-6% calcium, 3-6% magnesium, 2-5% iron, and 1-2% titanium. To more fully understand this, it helps to know how the Moon came into existence and the general processes that occurred in its history. All other elements are present in amounts very much smaller than 1% by weight.

On average two or three times a year the Moon happens to be at a point not far above or below the plane of the Earth's orbit during a full moon and a lunar eclipse can be observed from Earth. In fact, 71 percent of earth’s …

Planet Earth is made up of a number of elements. Earth’s Moon.

Looking particularly at the last moon-forming impact scenarios, the scientists assessed the likelihood that Theia and Earth had the same chemical composition.

Despite its size, it is second only to Jupiter’s moon in terms of density. Due to the moon’s synchronous rotation with the Earth, only one side of the moon … The moon is situated 384, 000 km away from the earth. For the Moon to be in position to move into the Earth's shadow, it must be in the full moon position.

Below this is the mantle followed by the outer core and the inner core.

The Origin and Composition of the Moon. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. Find out more about composition of the Sun, Earth and Moon! The Moon is the only natural satellite of Earth and is the 5th largest natural satellite in the solar system with an equatorial radius of 1,738 km.
During the Apollo program of the 1960s and '70s, NASA sent nine missions to the Moon.

Trace amounts of carbon dioxide, water vapor, and other gases are also present.
The earth is situated 149, 668, 992 km (93, 000, 000 miles) from the sun.

"The moon flies through Earth's atmosphere," says Igor Baliukin of Russia's Space Research Institute, lead author of the paper presenting the results. It is important to first understand what the Moon is made of, and how it compares and differs from Earth and asteroids. Finally, the core is mostly iron metal. Sun – The sun is a star about 330,000 times the size of the earth. Though it remains the prevailing hypothesis, the giant impact theory is far from an open-and-shut case.

Also, the moon does not have water, but the earth has water. The Moon was likely formed after a Mars-sized body collided with Earth several billion years ago. The composition of the atmosphere of Earth is 21 percent molecular oxygen, 78 percent molecular nitrogen, and 1 percent argon. The central core of the Earth is …
