what is the composition of the moon compared to earth?
476052
Surface composition The average composition of the lunar surface by weight is roughly 43 percent oxygen, 20 percent silicon, 19 percent magnesium, 10 percent iron, 3 percent calcium, 3 percent aluminum, 0.42 percent chromium, 0.18 percent titanium and 0.12 percent manganese.

Put another way, Earth weighs 81 times more than the moon. The moon's density is 3.34 grams per cubic centimeter (3.34 g/cm3).

Beneath its thin coating of crushed rock, the Moon has three layers—a crust, a mantle, and a core. As on Earth, the crust is the outermost layer. It averages about 70 kilometers (about 40 mi) thick and contains the least dense type of rock. Beneath the crust is a thick mantle that makes up most of the Moon's volume.

The Sun is made up of hot clouds of gases, but the Earth and the moon are simply made up of rocks. The moon revolves around the Earth, the Earth revolves around the Sun and the Sun revolves around its own axis. The earth is a planet, the Sun is a star and the moon is a natural satellite.

The main difference between the two is that Earth has processes that can erase almost all evidence of past impacts. The Moon does not. Pretty much any tiny dent made on the Moon's surface is going to stay there. Three processes help Earth keep its surface crater free.

The moon orbits the Earth and the Earth orbits the sun . A similarity for all of them is that they are all in the same galaxy, The Milky Way. A similarity for the moon and the sun is that both can't support life. A similarity is that the Earth ,moon ,and the sun are all involved in lunar and solar eclipses.

The distance between the Earth and its moon averages about 238,900 miles (384,000 kilometers). The diameter of the moon is 2,160 miles (3,476 kilometers). The moon's mass—the amount of material that makes up the moon—is about one-eightieth of the Earth's mass.

Renewable Energy on the Moon Resources on the Moon are abundant. Platinum, silicon, iron, titanium, ammonia, mercury, and even water have been proven to exist on the Moon. However, the one resource that is very rare on Earth but abundant on the Moon is helium-3.

Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.

The maria are much less cratered than the highlands, and cover just 17% of the lunar surface, mostly on the side of the Moon that faces Earth (Figure 3b). Today, we know that the maria consist mostly of dark-colored basalt (volcanic lava) laid down in volcanic eruptions billions of years ago.

Earth. Scientists only recently learned that our moon is mostly made of the same basic material as Earth, likely a result of its troubled birth. As our planet was forming, astronomers think it collided with a Mars-sized body they've named Theia. ... could fit between it and Earth.

Pluto is about two-thirds the diameter of Earth's moon and probably has a rocky core surrounded by a mantle of water ice. Interesting ices like methane and nitrogen frost coat its surface.

Surface temp. The Moon is an astronomical body orbiting Earth and is the planet's only natural satellite. It is the fifth-largest satellite in the Solar System, and by far the largest among planetary satellites relative to the size of the planet that it orbits.

Mass, density and gravity The moon's mass is 7.35 x 1022 kg, about 1.2 percent of Earth's mass. Put another way, Earth weighs 81 times more than the moon. The moon's density is 3.34 grams per cubic centimeter (3.34 g/cm3). That is about 60 percent of Earth's density.

The Moon is smaller than the Earth and orbits around the Earth in 27.3 days as the Earth revolves around the Sun. The Moon is held in orbit around the Earth by the force of gravity. In turn the Earth and all the other planets in the solar system are held in orbit around the Sun by the force of gravity.

Earth's atmosphere is composed of air. Air is a mixture of gases, 78% nitrogen and 21% oxygen with traces of water vapor, carbon dioxide, argon, and various other components.

The Moon has no atmosphere at all, except for traces of solar wind gases, that quickly escape into space. Comparison of Mars and Earth orbits shows that Mars' is much more eccentric than the Earth's. ... The average distance between Earth and Mars is over 200 times as far as it is from the Earth to the Moon.
