The crust of the Moon is composed mostly of oxygen, silicon, magnesium, iron, calcium, and aluminum. There are also trace elements like titanium, uranium, thorium, potassium and hydrogen. Want to compare the Moon to other objects in the Solar System? Here’s what the Earth is made of, and here’s what Mars is made of.
Also question is, what is the surface features of the moon?
Probably the most well-known features of the moon are craters. Craters are very round basins that can be one inch or hundreds of miles across. The majority of the moon’s craters are impact craters, which formed when meteoroids, asteroids, or comets collided with the moon’s surface.
What materials are found on the moon?
Elements known to be present on the lunar surface include, among others, oxygen (O), silicon (Si), iron (Fe), magnesium (Mg), calcium (Ca), aluminium (Al), manganese (Mn) and titanium (Ti). Among the more abundant are oxygen, iron and silicon.
What is the composition of the moon’s surface?
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.
What would you find on the surface of the moon?
The moon’s surface is covered with dead volcanoes, impact craters, and lava flows, some visible to the unaided stargazer. Early scientists thought the dark stretches of the moon might be oceans, and so named such features mare, which is Latin for “seas” (maria when there are more than one).
How hot is the surface of the moon?
Daytime on one side of the moon lasts about 13 and a half days, followed by 13 and a half nights of darkness. When sunlight hits the moon’s surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 C).
Can you live on the moon?
First, yes, it makes sense to want to colonize Mars, because it is more similar to Earth than the Moon. Sure, we may not ever be able to live there—Mars might be better for that—but we can at least build a lunar base that serves as a research center and hub for star-skimming travel.
What are the three main features of the moon?
While the craters, highlands and maria are the moon’s three main landforms, the moon’s surface has a number of other highly visible features. For example, some impact craters have bright rays that shoot outward from the center. Also, the moon has a number of rilles, which are long, thin tunnels or trenches.
How big is the surface of the moon?
“If Earth were the size of a nickel, the moon would be about as big as a coffee bean,” according to NASA. The moon’s surface area is about 14.6 million square miles (38 million square kilometers), which is less than the total surface area of the continent of Asia (17.2 million square miles or 44.5 million square km).
What is older than the moon?
The moon is a very old soul, it turns out. A new analysis of lunar rocks brought to Earth by Apollo astronauts suggests that the moon formed 4.51 billion years ago — just 60 million years after the solar system itself took shape.
What is the main gas on the moon?
The Apollo 17 mission deployed an instrument called the Lunar Atmospheric Composition Experiment (LACE) on the moon’s surface. It detected small amounts of a number of atoms and molecules including helium, argon, and possibly neon, ammonia, methane and carbon dioxide.
What is the definition of a moon?
moon. A natural satellite of a planet; an object that revolves around a planet. The planets vary in the number of their moons; for example, Mercury and Venus have none, the Earth has one, and Jupiter has seventeen or more. The planets’ moons, like the planets themselves, shine by reflected light.
Why is the moon so cratered?
Craters on the Moon are caused by asteroids and meteorites colliding with the lunar surface. The Moon’s surface is covered with thousands of craters. Why does the Moon have so many craters compared to the Earth? Unlike the Earth, the Moon has no atmosphere to protect itself from impacting bodies.
How did the moon form?
The giant-impact hypothesis, sometimes called the Big Splash, or the Theia Impact suggests that the Moon formed out of the debris left over from a collision between Earth and an astronomical body the size of Mars, approximately 4.5 billion years ago, in the Hadean eon; about 20 to 100 million years after the solar
How does the moon travel?
The Motion of the Moon. The Moon moves around the Earth in an approximately circular orbit, going once around us in approximately 27.3 days, or one sidereal period of revolution. As it does this its position changes, relative to the stars.
What kind of rock is on the moon?
The composition of the rocks on the moon based on samples of lunar rocks are volcanic in origin. The rocks are basalts, similar to the kind of volcanic rock found on Earth. The lunar basalts are rich in iron and magnesium, and they also contain glassy structures that are indicative of rapid cooling.
What are moon rocks made of?
Moon rocks are not exactly a type of marijuana strain, but more of a cannabis experiment. Typically, they’re are nuggets of the marijuana strain Girl Scout Cookies, dipped in hash oil and then sprinkled with kief.
What is the moon Is it a star?
Well, not really, as a planet is an object that orbits a star, and the Moon orbits the Earth (and yes, wannabe pedants, it really does orbit the Earth and not the Sun). A satellite is a generic term for an object that orbits another object.
Why do you always see the same side of the moon?
Only one side of the Moon is visible from Earth because the Moon rotates on its axis at the same rate that the Moon orbits the Earth, a situation known as synchronous rotation or tidal locking. The Moon is directly illuminated by the Sun, and the cyclically varying viewing conditions cause the lunar phases.
How is the moon lit?
The moon shines because its surface reflects light from the sun. And despite the fact that it sometimes seems to shine very brightly, the moon reflects only between 3 and 12 percent of the sunlight that hits it. The perceived brightness of the moon from Earth depends on where the moon is in its orbit around the planet.
Where did the Moon come from?
The leading explanation for the moon’s origin, known as the Giant Impact Hypothesis, was first proposed in the 1970s. It suggests the moon resulted from the collision of two protoplanets, or embryonic worlds. One of those was the just-forming Earth, and the other was a Mars-size object called Theia.
Is the moon a satellite?
The Moon is an astronomical body that orbits planet Earth and is Earth’s only permanent natural satellite. It is the fifth-largest natural satellite in the Solar System, and the largest among planetary satellites relative to the size of the planet that it orbits (its primary).
Is there water on the moon and if so where it is?
Liquid water cannot persist at the Moon’s surface, and water vapor is decomposed by sunlight, with hydrogen quickly lost to outer space. However, scientists have since the 1960s conjectured that water ice could survive in cold, permanently shadowed craters at the Moon’s poles.
What is a fun fact about the moon?
The Moon (or Luna) is the Earth’s only natural satellite and was formed 4.6 billion years ago around some 30–50 million years after the formation of the solar system. The Moon is in synchronous rotation with Earth meaning the same side is always facing the Earth.
