You observe a distance solar system with 4 rocky planets orbiting close to their star in a clockwise direction and 4 gas giant planets orbiting far from their star in a counterclockwise direction. Is this solar system consistent with being formed via the nebular theory? Explain your reasoning.

Answer #1

No, this solar system is not consistent witht he Nebular theory. The reason is mentioned below.

Nebular theory explains three observable facts.

  1. Planets all rotate in the same direction.
  2. All orbit within 6 degrees of a common plane.
  3. All the terrestrial planets are those within the orbit of the Asteroid Belt, are rocky, while those outside it are gaseous.

The theory also explains the existence of the Kuiper Belt -- a region on the fringes of the solar system with a high concentration of comets.
