What is the weight of a meteorite?
- Weight / sensations of density: Siderites are the densest of meteorites : from 7 to 8 g/cm3 (by comparison, terrestrial rocks have a density of 2,7 to 3 g/cm3). Compared to their volume, they will therefore be very heavy.
What are the three main families of meteorites? How to recognize a Meteorite

- 2) The Achondrites.
- 3) The meteorites ferrous (siderites)
What is the difference between an asteroid, a meteorite and a comet?
The asteroids are smaller than a planet, but they are bigger than the meteorites the size of a pebble. Sizes range from 1 meter to around 1000 km. They are also called minor planets.
What is the weight of a meteorite?

A fragment of 477 kilos, the largest ever found in France, was notably discovered in the area.
Who deals with meteorites?
Meteorologists and hunters meteorites distinguish the "falls", meteorites that we saw fall on Earth and that we found shortly after their landing, "finds", meteorites discovered by chance without which their fall has been observed.
What is the composition of a meteorite?
Composition the meteorites of iron are made of an alloy composed on average of 90% iron and 10% other chemical elements such as nickel, iridium, chromium and gallium. This alloy is commonly called meteoric (or meteoritic) iron, or simply iron-nickel.
What is the difference between a comet and an asteroid? The asteroids are, the vast majority of which are geologically dead bodies composed of rocks, metals and ice. The comets are consisting of a core of ice and rock which between in activity by sublimation (transition from the solid state to the gaseous state) of the ice when they approach the Sun.
What is the difference between a meteorite and a shooting star? A shooting star, vs'is a comet fragment. When we see her, by the time you warn the person next to you, it'sis already finished!

What is a crater formed by a meteorite called? the crater Manicouagan is one of the finest examples of crater impact in the world. This impact would have been caused by a meteorite 8 km in diameter, 214 million years ago, at the end of the Triassic era.
How to measure the density of a meteorite?
A more accurate method for measuring the density for the meteorite is to use Archimedes' thrust: "Any body immersed in a liquid receives a vertical thrust directed from bottom to top, equal to the mass of the volume of the displaced liquid".
What are the 3 most abundant chemical elements in a chondrite type meteorite? The chondrites are classified according to their mineralogical composition. Chondrites ordinary: 80% of chondrites ; they contain olivine, bronzite, plagioclase (see Table 1) and other iron-based minerals. They are divided into two subgroups, H and L.
What is the composition of meteorites?
With the exception of the most oxidized achondrites and chondrites, meteorites are magnetic, containing a metal made up of two alloys of iron and nickel: kamacite (5 to 10% nickel) and taenite (more than 15%).
What is the difference between comet and asteroid? In summary, the differences are mainly in their composition and density. Mainly made up of volatile materials, comets display an activity that distinguishes them from asteroids. However, cometary nuclei having exhausted their ice reserves can become asteroids in disarray.
What is the difference between a comet?
The comets are also bodies from the solar system. But at the difference of a meteorite and an asteroid, the comets have a core, made of ice and dust. When it approaches the Sun, a thin atmosphere forms around the comet, the hair. It can then be visible from Earth.
How to recognize a comet? The comet, a star of ice and dust
The resulting luminous halo is called “hair” or “coma”. It is the whole core and hair which constitutes the head of a comet. This head is followed by a double tail, which forms opposite the Sun and can extend up to 100 million kilometers!
