Many Asteroids come from Five Ancient Lost Planets that were Once Whole

While asteroids and meteorites have been thought to be planets that failed, actually most of them in the solar system come from five ancient planets that were once large enough to qualify as heavenly bodies.

A research effort showed that the majority of the 200,000 asteroids in our solar system come from five or six ancient planets. These often come near the earth and moon in the form of meteorites. The minority of asteroids also come from the same five ancient bodies.

This research highlights the formation of some of the planets of our solar system. These include the earth. Asteroids have a whole history that is based on evolution behind them.

Such a study could provide valuable material that helps scientists invent methods of saving the earth from meteorites that are large enough to do a lot of damage.

The fact that most asteroids come from the same five ancient planets means that their nature has a common point of origin. By understanding their evolutionary history, we can well understand how to deflect them were they to approach the earth thereby threatening our species.

Actually, the sort of orbit an asteroid possesses is dependent on the size of the asteroid. All the asteroids that could be spotted by astronomers in the asteroid belt came from the same five or six heavenly bodies that existed in ancient times.

The existence of these ancient bodies was relevant four billion years ago. Then collisions and destruction took place. The results can be seen today in the asteroid belt of the solar system.

All this has an application in the case of our own planet. The asteroids that came from approximately five ancient worlds happen to be a treasure house of information for astronomers.

The findings of this study appeared online in the journal Nature Astronomy.
