SOLAR SYSTEM

Detailed explanation-1: -An asteroid would be likely be the visitors of our planet because the Earth is near the asteroid belt between mars and Jupiter. It would likely cross our orbit unlike a comet that thousand years more to visit us again.

Detailed explanation-2: -The C-type (chondrite) asteroids are most common. They probably consist of clay and silicate rocks, and are dark in appearance. They are among the most ancient objects in the solar system. The S-types ("stony") are made up of silicate materials and nickel-iron.

Detailed explanation-3: -If the asteroid hits on land, there would be a huge amount of dust thrown up into the atmosphere. If it hits in water, then there would be an increase in water vapor in the atmosphere. This would result in an increase in rain resulting in landslides and mudslides.

Detailed explanation-4: -Most of this ancient space rubble can be found orbiting the Sun between Mars and Jupiter within the main asteroid belt. Asteroids range in size from Vesta – the largest at about 329 miles (530 kilometers) in diameter – to bodies that are less than 33 feet (10 meters) across.
