Not sure about ateroids. If you means asteroids, the Minor Planets Centre, the organisation responsible for collecting observational data for such objects, there was enough information for over 600,000 asteroids for them to have a formal designation - a number.
The current estimate is that there are over 1,000 known asteroids with a diameter of 0.5 miles or larger that come close to Earth's orbit, but many more smaller ones exist. The actual number may vary as new asteroids are discovered and others go out of range.

It doesn't seem that scientists are anywhere near to knowing the total number of asteroids in the Kuiper belt.
A band of asteroids, also known as an asteroid belt, is a region in space between Mars and Jupiter where a large concentration of asteroids are found. These asteroids vary in size, shape, and composition, and are thought to be remnants from the early solar system. The most well-known asteroid belt is the Main Asteroid Belt, located between the orbits of Mars and Jupiter.
Some asteroids are considered associated and are called "groups." Most asteroids are not part of groups but are in a "belt" positioned between Mars and Jupiter. Certain zones of gravitional equilibrium can capture asteroids. These zones are known as LaGrange Points. Jupiter, having the most powerful planetary gravity, has several groups at these points. Two of them, because the individual asteroids in them are named after heroes in the Trojan War, are known as "Trojan asteroids." One group is the "Trojan" group and another is the "Greek" group, even though there's an important Trojan in the Greeks and an important Greek with the Trojans.
The current estimate is that there are over 1,000 known asteroids with a diameter of 0.5 miles or larger that come close to Earth's orbit, but many more smaller ones exist. The actual number may vary as new asteroids are discovered and others go out of range.
The total number of asteroids in the solar system is not known with certainty, as many asteroids are small and difficult to detect, and new asteroids are constantly being discovered. However, astronomers estimate that there are millions of asteroids in the asteroid belt between Mars and Jupiter, and potentially trillions of objects in the Kuiper Belt beyond Neptune. In addition, there are also a number of asteroids that do not reside in either the asteroid belt or Kuiper Belt, but instead follow their own unique orbits. These objects are sometimes referred to as "rogue asteroids," and their exact number is not known. Overall, while the exact number of asteroids in the solar system is uncertain, it is clear that there are many millions, if not trillions, of these small rocky bodies orbiting the sun.
There are no known asteroids or comets that have impacted Mercury.
Asteroids that occasionally cross the orbit of Earth are known as Near Earth Asteroids. Asteroids that both cross the orbit of the Earth and are large enough to pose a significant threat in the event of an impact are known as Potentially Hazardous Asteroids.
planetoids.
Yes.
The planetoids are also known as planetesimals, as well as asteroids.
The number of asteroids cannot be counted. It is like counting the number of grains of sand on a beach.
yes because they have an orbit
it states that 1772
An asteroid is known as a minor planet that orbits the sun. As of 2010 there have been 530,091 asteroids discovered.
It's asteroids, of course!
