Planets in the outermost orbits were likely to travel out of the solar system. Which of the following is an explanation for this?
a)The gravitational attraction between the planets and the sun was very strong due to a large distance between them.
b)The speed of the planets must be very slow to remain in orbit, regardless of the gravitational attraction.
c)They were sucked into a black hole nearby.
d)The gravitational attraction between the planets and the sun was very weak due to a large distance between them.

option d seems to be correct
Explanation:

Answer:
D
Explanation:
Gravitational force depends on the distance between the objects and their masses.
Every object possess attraction force to which the second object with less mass is attracted. The first has to be a heavier one to pull less heavier objects.
Say,
A comb and a matchstick are placed in space,
which one attracts which?
Clearly the comb will attract the matchstick because comb is heavier than it.
But,if they are far from each other,the pulling force is weaker.
Hope this helps
