What are asteroids made from?

Answer 1

Comets are made out of ice. They will melt after millions and billions of years. They were so cold that it can't really melt fast like an ice cube.

Asteroids are made out of rock. there's an asteroid belt outside Earth, and now Astronomers are still discovering them.

Meteors was the same thing as Asteroid, so you don't really had to know them.

Answer 2

Asteroids are made of rock and metal and broken away pieces of planets. They are grouped into three categories: Stony, Iron-Nickel, and a mixture of the two. Most asteroids that we know about fall into the first category, and are made of Silicates. A small percentage are Iron-Nickel. The rest form the third type. I believe that they are made of rocky bits left over from the formation of the inner planets.

The run-of-the-mill asteroid is just one kilometer long. This asteroid would have a mass of two billion tonnes, of which 200 million tonnes would be iron, 30 million tonnes would be high-quality nickel, 1.5 million tonnes would be the strategic metal cobalt, and 7,500 tonnes would be a mixture of the platinum group metals whose average values at 1996 prices would be in the neighborhood of $20,000 per kilogram. That adds up to $150 billion for the platinum alone.

additional. Comets on the other hand are mainly made of frozen gases such as water, carbon dioxide, and methane. They may have collected a small quantity of dust as well.

There may well be no well accepted difference between the asteroids and comets.

[The Sudbury Crater in Canada was an asteroid that landed, and has been smeared out by geological movement. It is an important nickel deposit. ]

in the asteroid belt the asteroids contain either rock or metal but sometimes asteroids contain both rock and metal.
There's no one answer; it will depend on what atoms coalesced to form it. In general, we can expect predominantly silicate rocks with some metals; iron, magnesium, and the like. Based on the impact residues of asteroids which have struck the Earth, we can expect a higher-than-average proportion of iridium.

Answer 3

the asteroids that are nearest to the sun is mostly made out of carbon while the ones further away are made out of silicate rock

Answer 4

Astriods are made of rocky,odd shaped objects smaller than planets

Answer 5

comets have tails and are made up of ice and dust. as for the others.. i dont know

Answer 6

they were maded when dinosaurs had sex

Answer 7

Metal And Rock

Answer 8
