According to the nebular hypothesis, which of the following sequences of events are chronologically correct?
Interstellar cloud, solar nebula, accretion, collisions between planetestimals, planets
Which solar system object has the most elliptical orbit?
Astronomers believe that the satellites of the Jovian planets were ______.
Planetestimals orbiting the growing planet
The Sun's mass is composed of ____ of elements other than Helium and Hydrogen.
Why was the recent discovery that planets more massive than Jupiter orbit near-by stars in small orbits surprising?
Because according to the nebular hypothesis, massive planets should only form away from their star

Which solar system object has on oort cloud?
The 1st planet from the Sun is _____.
Which of the following statements is a critical issue resulting from such comparison?
Only very massive planets can form very near the star of extra-solar systems and the orbits of extra-solar planets can be very elliptical, suggesting that planets may migrate
Which solar system object has an asteroid belt?
Which planet group contains craters?
Which planet group contains many satellites?
A successful theory of the solar system must be able to primarily explain:
The fact that the planetary orbits lie approximately in the same place
Which solar system object is 10km?
Which of the following objects is not a member of the solar system?

Which of the following explains the fact that the Jovian planets have more hydrogen and helium than terrestrial planets?
The higher temperatures near the center of the solar nebula prevented the condensation of hydrogen and helium in the inner part of the disk
The discovery of extra-solar planetary systems supports the idea that over time, planets may migrate inward.
As seen from the north celestial pole, the planets orbit the Sun in a clockwise direction.
The fact that some satellites and planets have cratered surfaces supports the hypothesis that planets and satellites were bombarded by planetestimals.
The discovery of extra-solar planets confirm Bode's Law.
