279,722 at last count and growing constantly. That includes Dwarf Planets and comets.

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.
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.
Saturn has not been found to have any asteroids in orbit around it. Instead, Saturn is known for its numerous moons, with the current count being 82 natural satellites.
If you mean asteroids within our Solar System, then stars. In the Universe, there will be many more asteroids than stars.
An asteroid is known as a minor planet that orbits the sun. As of 2010 there have been 530,091 asteroids discovered.
Several hundred thousand asteroids are currently known and catalogued; probably at least that many are there in the asteroid belt but are too small to be visible from Earth.
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.

the asteroids crashed in Asia have 1000 asteroids
Yes.
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.
The planetoids are also known as planetesimals, as well as asteroids.
It is unknown as not much is known about Eris at this point. However, it is not likely that Eris has had many encounters with asteroids given its positions in the solar system. It probably, has had more thane a few encounters with comets, however.
