Asteroids contain valuable heavy metals such as palladium, gold, rhodium, platinum, iridium etc. Surveys have deduced that the asteroid 241 Germania could yield profits of up to $95 trillion, that's just one of 600,000 asteroids surveyed for composition.
Because many valuable metals like platinum are dense so most of them have sunk into the molten center of the earth at some point during history leaving relatively small amounts in the crust. This cannot happen in an asteroid as there is nowhere for valuable metals to sink so they remain easily retrievable. That's why so many metals that are rare on earth are plentiful in asteroids, thus making them valuable.
Some people refer to asteroids as "space trash" because they are often seen as leftover debris from the formation of the solar system, primarily composed of rock and metal. Unlike planets, which have cleared their orbits, asteroids share space with other objects and can be perceived as clutter. Additionally, the term "trash" conveys a sense of potential danger, as some asteroids can pose threats to Earth due to their orbits. However, it's worth noting that asteroids also hold valuable resources and scientific insights.
By asteroids impacting the surface.
Typically, asteroids are silicates (rocks) and water (in the form of ice), which is pretty much the same stuff that comets are made of, except that the big, beautiful comets are mostly water, and the asteroids are mostly rock. Asteroids may also have some metals and someday these may be commercially valuable.
I think it might be because it can fall down into the earth one day.
Comets are Comets and Asteroids are Asteroids
Asteroids should be watched carefully because they have the potential to collide with Earth, causing significant damage and loss of life. By monitoring asteroids, scientists can track their movements and potentially take action to mitigate the threat of a collision. Additionally, studying asteroids can provide valuable insights into the history and composition of our solar system.
the asteroids crashed in Asia have 1000 asteroids
No asteroids have atmospheres.
meteoroids
Asteroids that might hit the Earth , a new planet in the solar system, and distant planets that humans might be able to live on, ect.
Stars are tremendously larger than asteroids and do not become asteroids.
