Is there a reason why planets in the solar system?

Is there a reason why planets in the solar system are all on roughly the same plane? Seems like all planets circle round the sun on the X-axis and not at an angle or about the Y-axis?

extreme2k,

Ever see Pizza dough spun in the air and stretch into a thin disk. Well the dust collecting aound some central rotating mass acts the same way and the dust tends to forma a spinning disk.

As other mass start to coagulate from that spining disk they all have simular rotational axis.

MacM,

Thanks for the reply. I understand how the pizza analogy works but however I am not quite sure if the planets revolving around the sun works the same way?

Its because the planets dont 'link' to each other in the same way as a pizza and its vacuum in between the planets.

xtreme2k,

The analogy was only for the dust disk from which planets formed. The connection is gravity. In the pizza it is molecular bonding. But individual atoms are coupled in both cases across voids of space.
