14 of 24
what is an Asteroid?
small solar bodies composded mainly of rock and non volatile minerals
15 of 24
how do asteroids form?
remenants of the solar system formation that failed coalesce because of the gravitional interference of Jupiter
16 of 24
How did the Solar system form?
1) A rotating cloud of gas and dust called a nebular cloud 2)The cloud collapsed due to gravity forming a rotatijng disc 3) largest mass collected in the centre forming the sun 4)The remaining material stuck together forming the plantets =accretion
