The mantle is ' most likely made of minerals like olivine and pyroxene, which are made up of magnesium, iron, silicon, and oxygen atoms.' The moon's crust is made of oxygen, silicon, magnesium, iron, calcium and aluminum, as well as small amounts of titanium, uranium, thorium, potassium and hydrogen. Its core is ' iron-rich,' according to NASA. The moon has three layers: core, mantle, and crust.

Maybe you've heard the phrase, 'the moon is made of green cheese.' The moon is made of various minerals. How hot is the sun? Get to know the blistering temperatures of the star's surface, core What is the moon made of? NASA picks crew for moon mission: Meet the four astronauts on Artemis II mission The moon is Earth's sole natural satellite. It orbits our planet in an elliptical path and is the fifth largest of over 200 moons in our solar system, according to NASA.

Is there water on the moon? Breaking down lunar discoveries through the years Is the moon a planet? Just curious? We're here to help answer life's everyday questions The moon, however, does have inconsistencies in its gravitational field because of ' Bouguer' gravity anomalies. NASA's GRAIL mission measured these mass anomalies which result from ' either variations in crustal thickness or crust or mantle density.' In turn, some areas on the moon's surface have stronger gravity while others have weaker. When the gravitational pull is smaller, someone weighs less. Since the moon's surface gravity is one-sixth of Earth's, this is why astronauts' movements appear bouncier. In comparison, the Earth has a surface gravity of approximately 9.8 meters per second squared. The moon has a surface gravity of around 1.62 meters per second squared, according to NASA. It's time to get to know how the moon's gravitational field works and answer some other interesting questions about Earth's nearby satellite. If people move differently on the moon than on Earth, does that mean the moon has no gravity? Gravity is ' the force by which a planet or other body draws objects toward its center,' according to NASA. Their movements appear bouncier and lighter than how we move on Earth, and this is thanks to gravity.
