What are some prominent features of the asteroid belt?

Asteroidní pás obsahuje 98,5% známých asteroidů sluneční soustavy a rozprostírá se mezi asi 2 astronomickými jednotkami (Au nebo vzdálenost Země) na 3,3 AU od Slunce. It contains between 700,000 and 1.7 million asteroids with a diameter of 1 km, but its total weight is only about 4% of the month. Asteroidní pás obsahuje průměr trpasličí planety 900 km, Ceres a tři velké asteroidy, Vesta, Pallas a Hygiea, s průměrným průměrem 450 km. Together, these bodies make up half of the asteroid belt mass. Zbývající většina protoplanetárního disku se stala planetami, spadla na slunce nebo byla vypuštěna v excentrických drahách jako komety. Another stable area is the Kuiper belt, which is located in front of the orbit of the Neptune, safe from the gas giants.

Unlike the fiction display, the asteroid belt looks relatively thinly closely. Numerous unmanned spacecraft passed through it without a noticeable collision. However, any long -term colonies would probably require a slightly stronger than the usual withgravity. The asteroid belt could also be a huge source of resources in the future. Lardy, silicates and metal asteroids have found that at current prices there would be many trillion dollars if they could be used.

Due to the gravitational agitation of Jupiter, the asteroid belt never becomes into the planetary body. If it happened, it would have done it long ago. Constant collisions between the bodies of asteroid strips cause to disintegrate faster than they are aggregated. The dust of these collisions has too little matter to remain in a stable solar orbit and slowly spirals down into the Sun of 700,000 years, producing a weak glow in the dark night sky known as Zodiacal Light.
