KOMPAS.com – Comet and asteroid is the name of a celestial body that is often heard in everyday life. Comets are different from asteroids, but they have something in common. What are the similarities and differences comet with asteroids?
Formed at the beginning of the formation of the solar system
Reported from Cool Cosmos, comets and asteroids were both formed in the early days of the formation of the solar system. That is, about 4.5 billion years ago.
Dark color
What comets and asteroids have in common is that they are both dark in color. The dark color of asteroids is produced by rocky and metallic materials. Meanwhile, the dark color of comets is produced by organic substances that coat the ice.

orbit the sun
Comets and asteroids are both celestial bodies that orbit the sun as the center of the solar system.
The position of the formation with respect to the sun
Even though they form at about the same time, comets and asteroids have different formation positions with respect to the sun.
Scientists predict that asteroids formed in areas closer to the sun. Meanwhile, comets form in areas farther from the sun where the comet-forming ice does not melt due to the heat of the sun.

Composing materials
The next difference between comets and asteroids is the composition of their constituent materials.
Asteroid formed from rocky and metallic materials such as clay, silicate, iron, nickel, and balsatic lava.
Meanwhile, comets are formed from ice covered with organic compounds, dust, and also rocky material.
The shape and trajectory of the orbit
The next difference between comets and asteroids is the shape and trajectory of their orbits. Reported from Universe Todaythe asteroid has a shorter and more circular orbit.
