Those asteroids that seem different might have their origins in the same body. 

New spectroscopic tools offer a window to asteroid chemistry. And that brings big surprises to researchers. The new observations tell. That asteroids might have an origin in the same body, even if they have different chemical compounds. And if those asteroids have chemical backgrounds that are far different from each other, that tells us that the bodies where those things are separated are very big. That opens a new way to see the solar system’s chaotic past.

There might be many other planets than the planets that we know in the young solar system. Some of those planets were destroyed in cosmic collisions. An interesting question is, how far those planets turned into solid form. When they faced their fate in the cosmic collisions. The asteroid’s rocky form suggests that its origin was in rocky planets or dwarf planets. 

The shape of those asteroids is sharp, and they seem like stones. That we see in quarries. Those signs indicate that the point where these stones separated during impact was in solid form. If the object were liquid, those asteroids should look smoother. And their shape would be more like a ball.  There is a theory that some asteroids in the asteroid belt and Kuiper Belt formed when some rocky planets collided. A recently mentioned theory tells that. The asteroid belt formed when a rocky planet was destroyed in cosmic collisions. 

Researchers said that those asteroids’ mass is not high enough. That they have formed a planet in the past. The fact is that most asteroids are quite small. And if we count the dust from the asteroid belt into the asteroid belt’s asteroid mass, that can be enough for quite a large planet, or protoplanet. And gas giants, Neptune, Uranus, Saturn, and Jupiter, clean their trajectories from smaller objects. Some of those large planets’ moons were asteroids before those gas giants captured them. And those giant planets can also drive asteroids a long distance from their original position. The chaotic past in our solar system is a very interesting period. Meteorite bombing was very intense, and Earth also faced the cosmic impact that separated our Moon from our planet.
