gravity
Objects that formed farther out than space are smaller than the planets because there is less matter available to form them further out from the sun. Less matter results in smaller objects, including asteroids and dwarf planets.
Planets have moons because matter is attracted by gravitational force to objects with a greater mass than them.That is why moons orbit planets and are never larger than their host planet.
The nebula will explode.

Gravity..
the solar system formed from a nebula of dust, that for some reason, the middle of the nebula was compressed forming a denser solid than the dust around it. so, having a larger gravitational pull the surrounding dust was drawn towards the middle of the nebula. as it moved in the nebula began to spin and due to the law of the conservation of angular momentum as a spinning objecting compresses it spins faster. so the nebula compressed and when a star (the sun) ignited the force of this formed other areas of compressed dust and this was how the planets formed and why the solar system orbits or spins.
A solar nebula is a place where new stars are formed. Stars are "born" here when giant dust and gas clouds are pulled together under the force of gravity.

The object would crash into the planet.
None. Following the laws of nature, planets are astronomical objects, and do not have moral attributes such as benificence or malevolence.

Newton
No an nebula is held together by the balance of the inward force of gravity and outward pressure.
The nebula will explode.

Gas and dust in a nebula is disturbed by an outside force
Planets revolve on their axis. Separate to this motion, they also orbit the Sun. The force of gravity and the momentum of the objects keep them going.
