Study Notes

Comets

Comets are icy bodies that, when close to the Sun, heat up and release gases, forming visible atmospheres called comas and sometimes tails.
Comets originated from the outer regions of the solar system, particularly the Kuiper Belt and Oort Cloud.

Meteors

Meteors are the streaks of light produced when meteoroids enter the Earth's atmosphere and burn up due to friction.
If a meteoroid survives its passage through the atmosphere and lands on Earth, it is classified as a meteorite.

Asteroids

Asteroids are rocky bodies that orbit the Sun, primarily found in the asteroid belt between Mars and Jupiter.
The largest asteroid is Ceres, which is also classified as a dwarf planet with a diameter of approximately 940 kilometers.

Composition of Asteroids

Asteroids are composed mainly of rock and metal, with some containing organic compounds and water ice.
Their composition reflects the conditions of the early solar system, providing insights into planetary formation.
