Question

how is an asteroid formed

Answer 1

They're formed at a birth of a star system.

Answer 2

The same way planets form, dust particles under the influence of gravity attract each other until they form bigger and bigger chunks of rock.

Answer 3

Asteroids are leftovers from the formation of our solar system about 4.6 billion years ago. Early on, the birth of Jupiter prevented any planetary bodies from forming in the gap between Mars and Jupiter, causing the small objects that were there to collide with each other and fragment into the asteroids seen today.
