Suppose the Sun had been born with less mass, making it a smaller, cooler star. Which of the following consequences would we expect according to the nebular theory?
A) The frost line would have been farther from the Sun, so jovian planets could form only at greater distances than in our solar system.
B) The frost line would have been closer to the Sun, so jovian planets could form at nearer distances than in our solar system.
C) The planets would have formed just as they did for our actual Sun, but the weaker gravity of a smaller Sun would have allowed the planets to escape into interstellar space.
D) There would have been no solar nebula in which material could condense to form planets.
B) The frost line would have been closer to the Sun, so jovian planets could form at nearer distances than in our solar system.
