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: -Ordinary chondrites are the most common type of stony meteorite, accounting for 86 percent of all meteorites that have fallen to Earth. They are named for the hardened droplets of lava, called chondrules, embedded in them.
Detailed explanation-3: -Meteorites have traditionally been divided into three broad categories: stony meteorites are rocks, mainly composed of silicate minerals; iron meteorites that are largely composed of metallic iron-nickel; and, stony-iron meteorites that contain large amounts of both metallic and rocky material.
Detailed explanation-4: -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-5: -It also causes the dust particles themselves to vaporize into hot, glowing gas. These burning particles of space dust, known as meteors, are commonly called shooting stars or falling stars. The bright streak of light created by their luminous vapors seems to move quickly across the sky before fading out seconds later.
