Planets

Question 9 • HOPE Scholars- Science Grade 8

Which two phrases describe the motion of all the outer planets?

Answer
A
no rotation, slow revolution
B
fast rotation, slow revolution
C
north-to-south rotation, slow revolution
D
no rotation, opposite revolution

Explanation

The outer planets rotate quickly on their axes, completing a spin in roughly 10 to 17 hours. They take much longer to revolve around the Sun, from about 12 years for Jupiter to 165 years for Neptune. So “fast rotation, slow revolution” describes their motion.
