What are asteroids and comets made of?

There are several different types of asteroid classification systems that are used, which is a classification and refers to somewhat confusing, even for astronomers. The basic outline common to all systems includes three-piece categories, known as type C, consists of 85% of known asteroids, silicon or rocky, type S, accounts for 17% of known asteroids and metal, called L-Type or X-TyP, which remains to 8% asteroid. These types are usually divided into different division based on spectral classification, albedo and guess their composition. Some special types of categorization, such as Q, R and V, are so rare that they are represented by only one asteroid.

Since June 4, 2007, 376,537 asteroids and smaller planets were registered with a measure of approximately 5,000 new organs per month. It is estimated that TZDE is between 1.1 and 1.9 million asteroids with a diameter of more than 1 km in the solar system andMany billions with a diameter of more than 10 m. Despite its fiction displaying, the asteroid belt between Mars orbit and Jupiter is not extremely dense - contains only a greater asteroid density than any other part of the solar system. Imagine only 1/1000. The size of the country is divided into small pieces and dotted with huge areas slightly larger than the Martian orbit. This is an asteroid belt. Because of the way the solar system of the solar system interacts in gravity, this area is a "sweet place" to end the debris.

Comets, despite their legendary bodies, are in fact one of the darkest objects in the solar system, reflecting only 3% - 5% of the incoming light. For comparison, the asphalt reflects 7% of light. This darkness comes from organic compounds, of which comets are made of z-long chains of carbon-containing molecules such as hydraocarbons. Imagine a ball of material similar to oil or coal. Comets also contain a large amount of ice and dust. For most of itCareers are black comets - only when their beautiful ion tails approach the sun. Most comets have highly elliptical orbit, approaching only a few months to the sun and spending hundreds or thousands of years in a deep solar system.

High carbon content in asteroids and comets could be useful for future efforts to colonize the universe. In the future, asteroids could be dismantled and processed to create a molecular raw material for gardens in space colonies. However, nitrogen would still have to come from planets or months.
