Which planet has the shortest day/fastest rotation?
Jupiter
The 4 largest moons of Jupiter are commonly known as the

Long term comets have orbital periods of greater than
200 years
The outer two planets are often called __________ _________ due to their relative size and temperature
ice giants
Pluto's orbit crosses Neptunes but never collides because they have a 2:3 orbital _________
resonance
The stripes across Jupiter that alternate direction are called ________ and ________. (you need both)
belts; zones
This moon is sometime referred to as a "young earth" due to its atmosphere and bodies of stable liquid on the surface.
Titan
The larest object in the asteroid belt is called
