What are the 3 main components of asteroids?
The three broad composition classes of asteroids are C-, S-, and M-types.
- The C-type (chondrite) asteroids are most common. They probably consist of clay and silicate rocks, and are dark in appearance.
- The S-types (“stony”) are made up of silicate materials and nickel-iron.
- The M-types are metallic (nickel-iron).
What are the components of asteroids?
They are made up of oxygen and silicon, the number one and number two most abundant elements in the Earth’s crust. The metallic asteroids are composed of up to 80% iron and 20% a mixture of nickel, iridium, palladium, platinum, gold, magnesium and other precious metals such as osmium, ruthenium and rhodium.
What resources are in the asteroid belt?
In addition to iron, nickel and magnesium, scientists think water, oxygen, gold and platinum also exist on some asteroids. Water interests space explorers most because it could help keep a space colony alive.
What keeps the asteroid belt in place?
Asteroids are relatively small rocky metallic objects that orbit the sun. Gravity keeps the asteroids in orbit around the sun, but the main asteroid belt we see today is only a tiny fraction of what used to exist and is predominately empty space. …
How much material is in the asteroid belt?
The total mass of the asteroid belt is estimated to be 2.39×1021 kilograms, which is just 3% of the mass of the Moon. The four largest objects, Ceres, 4 Vesta, 2 Pallas, and 10 Hygiea, account for maybe 62% of the belt’s total mass, with 39% accounted for by Ceres alone.
Do asteroids have metal?
S-type asteroids carry little water but look more attractive because they contain numerous metals, including nickel, cobalt, and more valuable metals, such as gold, platinum, and rhodium.
How fast does the asteroid belt move?
Asteroids zip through space at astonishing velocities. The speed at which asteroids move depends on their distance to the Sun. The closer they are, the greater the speed. That said, even Earth-crossing asteroids, or NEOs, travel around 25 kilometers per second — yep, per second!
