What Are Asteroids?
An asteroid is a small rocky object that orbits the Sun. Asteroids are smaller than a planet, but they are larger than the pebble-size objects we call meteoroids.
Asteroids, (sometimes called minor planets), are rocky, airless 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 the Sun between Mars and Jupiter within the main asteroid belt.
The Asteroid Belt
The asteroid belt is a disc-shaped region in the Solar System, located roughly between the orbits of the planets Jupiter and Mars. There are hundreds of thousands of asteroids located in the asteroid belt. Occasionally people wonder whether the belt was made up of the remains of a destroyed planet, or a world that didn't quite get started. However, according to NASA, the total mass of the belt is less than the moon, far too small to weigh in as a planet

Almost half of the entire mass of the asteroid belt is made up of just four objects. These objects are the dwarf planet Ceres, and three other asteroids- Vesta, Pallas and Hygiea.
Gravitational forces can throw asteroids out of the belt and send them towards the inner solar system

Specific Asteroids in the Belt
Ceres is a dwarf planet and is the largest object in the Asteroid Belt. Ceres makes up almost a third of the asteroid belt's total mass, but it is still far smaller than Earth's Moon. Ceres is heavily cratered with large amounts of ice underground.Ceres is geologically active as there are commonly eruptions of water

... Specific Asteroids in the Belt
Vesta is one of the largest objects in the asteroid belt, with a mean diameter of 525 kilometers. Vesta is thought to be the second-largest asteroid, both by mass and by volume. Vesta is also the brightest asteroid visible from Earth. Sometimes it is faintly visible to the naked eye


... Specific Asteroids in the Belt
Pallas is is the second asteroid to have been discovered (after Ceres). Pallas's orbit is unusually highly inclined to the plane of the asteroid belt, making Pallas relatively inaccessible to spacecraft. Studies suggest that Pallas’s surface is most likely composed out of silicate material (silicon-oxygen compounds)

What are comets?
Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ice. They can range from a few miles to ten miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet. This material forms a tail that stretches millions of miles.
