Explanation: 

Detailed explanation-1: -Most “iron” meteorites are iron-nickel alloy with a few scattered inclusions of sulfide minerals. The alloys are 5 to 12 percent nickel, with traces of cobalt, chromium, gold, platinum, iridium, tungsten and other elements that dissolved in the molten iron and traveled with it to the parent body’s tri.

Detailed explanation-2: -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. When a meteoroid survives a trip through the atmosphere and hits the ground, it’s called a meteorite.

Detailed explanation-3: -Complete answer: Many meteorites are formed from a collision of asteroids that rotate around the sun between the tracks of Mars and Jupiter in the region called the asteroid belt. As asteroids break into each other, they produce loose debris-meteoroids.

Detailed explanation-4: -Types of Meteorites More than 60, 000 meteorites have been found on Earth. Scientists have divided these meteorites into three main types: stony, iron, and stony-iron. Each of these types has many sub-groups.
