At the same time that the Earth (and the other planets) formed : 4.5 billion years ago.
They are concentrated between the Mars and Jupiter.
Scientists may not have named all of the asteroids in the asteroid belt because there are so many that they are hard to keep track of.
Because they have been observed and space probes have navigated through them.

About the same age as the time of formation of the solar system: 4.6 billion years to 4.7 billion years.

Scientists study asteroids to better understand the early solar system.
Scientists believe that asteroids originated from the leftover material from the early solar system's formation, primarily from the asteroid belt located between Mars and Jupiter.
Scientists think that the asteroid belt is a group of planetesimals (solid objects) that are caught between the gravity of Jupiter and the Sun.
It doesn't seem that scientists are anywhere near to knowing the total number of asteroids in the Kuiper belt.
A) Some scientists suppose that the asteroids represent pieces of a planet that once existed but was torn apart a long time ago. B) Other scientists believe that the asteroids are material that never came together to form a planet in the first place.
