One year on Jupiter takes ______________Earth years. 12.  Jupiter has _____________ confirmed moons. 13.  In 1610 __________________________was the first to see Jupiter’s four largest moons. 14.  Jupiter’s four Galilean Moons as they are called in honor of Galileo are: _____________ _______________________________________________________________________ 15.  Galilean moon, ________________, is the most volcanically acCve object in our solar system. 16.  See Table 1. Lava on Io is a mixture of _______________ and ______________ which gives it the disCncCve reddish orange colors. 17.  _______________________ is a Galilean moon slightly smaller than Earth’s moon that has an icy crust covering an OCEAN of salty water. Could life exist here??? 18.  Galilean moon, _______________________________, is the largest moon in our solar system. It is even bigger than Mercury! 19.  The final Galilean moon, ______________________, is heavily cratered. 20.  Table 1. Which Galilean Moon is large enough to generate is own magneCc field and even has a thin atmosphere of OXYGEN? ___________________________________ 21.  Table 1. Which Galilean Moon has a toxic atmosphere made of primarily sulfur dioxide? ________________________________ 22.  It is said that Saturn could float on water! Why? _______________________________ _______________________________________________________________________ 23.  Like Jupiter, Saturn rotates very rapidly. A day on Saturn = _____________Earth hours. 24.  It takes _______________Earth years for Saturn to complete one revoluCon around the Sun. 25.  Wind speeds in Saturn’s atmosphere which is 90% hydrogen and 10% helium, reach ______________________ km/hr. 26.  Saturn’s rings are made of ________________________________________________ ______________________________________________________________________ 27.  Saturn has ____ bands of rings. The main ring system is 70,000 km wide but less than _____ km thick. 28.  What is one hypothesis for how the parCcles in Saturn’s rings came to exist? ________ _______________________________________________________________________ 29.  Saturn has at least _________ moons but Figure 3 says it has ______ moons. 30.  Saturn’s five largest moons are:______________________________________________ _______________________________________________________________________ 31.  Saturn’s moon, ___________________, is larger than the planet Mercury and has a dense atmosphere. 32.  In 2005 the Cassini orbiter released the ___________________ probe which landed on Titan’s surface. It discovered seas and lakes of methane!! Methane is a gas on Earth but on colder Titan it is a liquid. It also determined that these lakes and seas are replenished by methane rainfall from the clouds in Titan’s atmosphere. A methane cycle vs. a water cycle!! 33.  _________________________ is the seventh planet from the Sun. 34.  The last Cme it was visited by a probe was in ______________ when Voyager 2 flew by. 35.  Uranus, like the other Gas Giants has a shorter day than Earth, rotaCng in just ________ Earth hours. 36.  It takes ____________Earth years for Uranus to complete on revoluCon. 37.  Uranus has ____________moons which we do not know much about and are not parCcularly interesCng….compared to Jupiter and Saturn’s moons. 38.  Uranus has an odd Clt on it’s axis. It is sideways on its axis. This is thought to have been caused by ________________________________________________________ 39.  The last Gas Giant, ___________________________, has 13 moons. 40.  Neptune’s largest moon is called ________________________ . It has geysers that erupt Nitrogen gas! 41.  Neptune’s __________________________________is a storm that was seen by Voyager 2 in 1989. The storm is now gone. 42.  If you could send a probe to learn more about the outer solar system, where would you send it and why. _________________________________________________________ _______________________________________________________________________ _______________________________________________________________________
