What is an asteroid?
Asteroids are rocky objects that orbit the Sun, much smaller than planets. They are also called minor planets. As per NASA, 994,383 is the count for known asteroids, the remnants from the formation of the solar system over 4.6 billion years ago.
Further down the same article.....
Most such objects can be found in the asteroid belt between Mars and Jupiter, which is estimated to contain somewhere between 1.1-1.9 million asteroids
... .then goes on to say.....
According to The Planetary Society, there are estimated to be around 1 billion asteroids having a diameter greater than 1 metre.
I think NASA should be asking The Planetry Society about these additional unknown asteroids.
