SOLAR SYSTEM

Detailed explanation-1: -Our solar system is very big compared to the size of the Earth, which means that the chance that the Earth will be hit by another solar system object such as an asteroid is very small.

Detailed explanation-2: -If the asteroid impacts a land mass, in addition to a huge shock wave, massive amounts of particles would be released into the atmosphere, causing serious environmental damage on a global scale and mass extinctions. As we know, the impact of large asteroids will have devastating effects no matter where they land.

Detailed explanation-3: -Astronomers estimate that modest-sized asteroids in the main belt smash into each other about once a year. Catching asteroids in the act of colliding, however, is difficult because large impacts are rare while small ones, such as the one that produced P/2010 A2, are exceedingly faint.

Detailed explanation-4: -The vast majority of bits of matter bound for collision have already collided, and the orbits of bigger bodies have settled down. Collisions are even rare within the asteroid belt-despite the rocky obstacle course that it tends to be portrayed as, it’s mostly empty space.

Detailed explanation-5: -The main asteroid belt, between Mars and Jupiter, is where most asteroids orbit.
