Question 3

What would happen to the planets in a solar system where the central star did not have a strong wind?

Accepted Answer

A) Nothing, the star does not affect the process of planet formation. 
B) One planet would grow to dominate all the others and gravitationally eject them out of the system. 
C) The gas in the solar nebula would create a drag on the planets and their orbits would migrate inwards. 
D) All planets would continue to grow to large sizes but their orbits would be unchanged. 
E) The gas in the solar nebula would create a drag on the planets and their orbits would migrate outwards.
