Question
The Grand Tack model helps to explain all of the following observations except which?
Mars has a relatively small mass.
The asteroid belt contains a few icy objects as well as many rocky objects.
Neptune’s current location would not allow it to grow rapidly enough to account for its large size.
The orbital motions of all the planets are in the same direction around the Sun.
a.Mars has a relatively small mass.
b.The asteroid belt contains a few icy objects as well as many rocky objects.
c.Neptune’s current location would not allow it to grow rapidly enough to account for its large size.
d.The orbital motions of all the planets are in the same direction around the Sun.
Explanation / Answer
d.The orbital motions of all the planets are in the same direction around the Sun.
Actually Venus and Uranus orbit in a different direction around the Sun. " The orbital motions of all the planets are in the same direction around the Sun" is not explained by Grand Tack model.
