Detailed explanation-1: -Meteoroids are objects in space that range in size from dust grains to small asteroids. Think of them as “space rocks.” When meteoroids enter Earth’s atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars ‘’ are called meteors.
Detailed explanation-2: -There are two main types of stony meteorite: chondrites (some of the oldest materials in the solar system) and achondrites (including meteorites from asteroids, Mars and the Moon). Both chondrites and achondrites have many subgroups based on their compositions, structures and the minerals they contain.
Detailed explanation-3: -Meteorites. A meteorite is a fragment of spatial matter that falls to the surface of a planet.
Detailed explanation-4: -Meteoroids are lumps of rock or iron that orbit the sun. Most meteoroids are small fragments of rock created by asteroid collisions. Comets also create meteoroids as they orbit the sun and shed dust and debris.
Detailed explanation-5: -Most meteoroids are made of silicon and oxygen (minerals called silicates) and heavier metals like nickel and iron. Iron and nickel-iron meteoroids are massive and dense, while stony meteoroids are lighter and more fragile.
