Lesson Four: Micro Planets, Comets, And Asteroids

Explanation
Comets are made out of ice and dust. Comets are celestial bodies that originate from the outer regions of the solar system. They are composed mainly of frozen gases, such as water, carbon dioxide, methane, and ammonia, which form the icy nucleus of the comet. Surrounding the nucleus is a cloud of dust particles, which is illuminated by the Sun, creating the characteristic coma and tail of the comet. The combination of ice and dust gives comets their unique composition and appearance.

Explanation
The Asteroid Belt is located between Mars and Jupiter. This region in our solar system is filled with numerous asteroids, which are rocky objects that orbit the Sun. The gravitational influence of Jupiter prevented the formation of a planet in this region, leading to the accumulation of these asteroids instead.

Explanation
The Kuiper Belt is a region in our Solar System located beyond Neptune. It is a disc-shaped region filled with small icy bodies, including dwarf planets such as Pluto. This region is believed to be remnants from the early formation of the Solar System and is home to many objects that have not been significantly altered since their formation.

Explanation
Ceres is the name of the micro planet located in the Asteroid Belt. It is the largest object in the asteroid belt and was classified as a dwarf planet in 2006. Ceres is named after the Roman goddess of agriculture and harvest. It was discovered in 1801 and has since been studied extensively by scientists, including the NASA Dawn mission which orbited Ceres from 2015 to 2018.

Explanation
In 1908, a large interstellar body struck the Earth's atmosphere and hit the region of Tunguska in Russia. This event, known as the Tunguska event, caused a powerful explosion, flattening trees and causing widespread damage. The impact was so strong that it is estimated to have been equivalent to the explosion of 10-15 megatons of TNT, which is a thousand times more powerful than the atomic bomb dropped on Hiroshima. The Tunguska event is one of the most significant impact events in recorded history.
