Lead author on the newly published research paper Stanley Dermott says it's likely that the remaining 15 percent could also end up being from old planets too.
Research into the asteroid belt offers insights into the way our own Earth was formed. It also gives scientists critical information about the formation of the asteroid and offers the opportunity to determine if any matter is going to peel off and head towards earth.
"These large bodies whiz by the Earth, so of course we're very concerned about how many of these there are and what types of material are in them," Dermott said in a press release. "If ever one of these comes towards the earth, and we want to deflect it, we need to know what its nature is."
The study discovered that the size of the asteroid determines its orbit. This discovery suggests that the differences we observe in meteorites found on Earth relate to the evolutionary changes that occurred inside a few large, vanguard bodies that existed more than four billion years ago.
“I wouldn’t be surprised if we eventually trace the origins of all asteroids in the main asteroid belt, not just those in the inner belt, to a small number of known parent bodies,” Dermott said. This research helps theoretical astronomers in their quest to investigate where planets like our own might exist in the universe.
But before those questions can be fully understood it is crucial to more fully understand the processes that produced the planet we live on. Last month NASA discovered an asteroid heading on a collision course with Earth.
