There is no way to determine an exact number for just in our Solar System, let alone all of space. The number keeps changing as they collide with each other either breaking off smaller asteroids or fusing together forming larger asteroids, or collide with planets or the sun and are destroyed. We can't see them around other stars, but there are inevitably some.

Yes, asteroids can be observed from space using telescopes equipped with advanced imaging technology. Spacecraft missions, like NASA's NEOWISE, have successfully detected and studied asteroids by capturing their infrared signatures. Additionally, some asteroids are large enough to be seen directly with optical telescopes from space. However, many smaller asteroids are challenging to detect due to their size and distance.
Stars are tremendously larger than asteroids and do not become asteroids.
Asteroids, astronauts, and auroras are examples of things in space that start with the letter "a."
Asteroids have no use as yet. They are simply rocks in space. Many science fiction writers, however, have theorized using asteroids for mining.
