SOLAR SYSTEM

Detailed explanation-1: -An estimated 25 million meteoroids, micrometeoroids and other space debris enter Earth’s atmosphere each day, which results in an estimated 15, 000 tonnes of that material entering the atmosphere each year.

Detailed explanation-2: -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-3: -The majority of meteorite finds are stony meteorites, consisting mostly of silicate minerals. 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).
