GENERAL KNOWLEDGE

Detailed explanation-1: -Asteroids, sometimes called minor planets, are rocky remnants left over from the early formation of our solar system about 4.6 billion years ago. Most of this ancient space rubble can be found orbiting our Sun between Mars and Jupiter within the main asteroid belt .

Detailed explanation-2: -Meteoroids are lumps of rock or iron that orbit the sun, just as planets, asteroids, and comets do. Meteoroids, especially the tiny particles called micrometeoroids, are extremely common throughout the solar system.

Detailed explanation-3: -The asteroid belt formed from the primordial solar nebula as a group of planetesimals. Planetesimals are the smaller precursors of the protoplanets. Between Mars and Jupiter, however, gravitational perturbations from Jupiter imbued the protoplanets with too much orbital energy for them to accrete into a planet.

Detailed explanation-4: -Although most asteroids travel in fairly circular orbits, there are notable exceptions. In addition to the near-Earth asteroids, some objects are known to travel in orbits that extend far inside or outside the main belt.
