Pretty much everyone can rattle off the names of our solar system ’s eight ( formerly nine ) planets , but ask the average person to list some Moon and you ’ll be lucky if they can tell you more than two or three .
Now , you patently ca n’t expect people to remember the name of every exclusive satellite in the solar organization ( after all , they outnumber the planet by around 20 to 1 ) , but if you have even the slightest interest in astronomy , it would n’t kill you to be familiar with at least an even ten . So with that in mind , we ’ve gather this reference usher to ten of the solar system ’s most noteworthy moons .
Sun Myung Moon : Europa
Parent Planet : Jupiter
Why You Should Know it : Despite being covered by distinctive , criss - crossing cracks and ridges , Europa ’s water - ice surface is largely costless of crater , making it perhaps the smoothest square trunk in the entire solar system . More interesting than Europa ’s frozen outside , however , is what lies hidden beneath it .

A uprise body of evidence suggest that there is a vast liquid ocean lurking underneath Europa ’s strong surface , and a lot of scientist are eager to tap this watery interior in search of life . As Michael Shara — curator of the astrophysics division at the American Museum of Natural History — told us : “ If we can figure out a way of putting a probe through the Methedrine … who knows what we could discover [ in the subsurface oceans of Europa ] . It would be gripping to go look , and I mean we have no option but to go attend ; we must do it . ”

Moon : Io
Why You Should Know it : Io is very closemouthed in size to our own moon , but it could n’t be more different . Despite sustain a mean surface temperature of less than -250 degrees Fahrenheit , Io is home to over 400 raging volcanos , making it the single most geologically participating aim in the solar organization .
synodic month : Mimas
Parent Planet : Saturn
Why you should know it : This list is an of import reference for any self - respecting scientific discipline geek , but Mimas is especially relevant for fans of science fiction for what should be obvious reasonableness . In brief : Mimas is no blank place . It ’s a moonshine . Like many of Saturn ’s revolve consistence , Mimas is lowly and wintry , but it ’s also home to “ Herschel ” — the name astronomers have hold the monolithic crater locate on the Sun Myung Moon ’s lead hemisphere .
At 139 - km wide , Herschel is almost one - third the diam of Mimas itself , causing the moon to bear a come to resemblance to the Death Star . Incidentally , Herschel crater was find three year after the release of A New Hope ( Star Wars has a way ofpredicting astronomical discoveries ) . Bonus geek points : Temperature map of Mimas reveal spicy region that look exactly like Pac - Man eat on a dot .

Moon : Enceladus
Why You Should bed it : Enceladus is one loco niggling synodic month . Like Europa , its surface is pass over in water methamphetamine hydrochloride , but it ’s also home to some of the most telling geysers in the solar organization . Scientists had suspected for years that Enceladus was ventilate water vapor from its surface , but it was n’t until 2005 that they had direct optical verification that the moon was doing so by spue jet-propelled plane of the stuff from geyser on its surface .
More recent images have revealed that this piddle vapor is expelled so violently that it nominate itall the way to Saturn itself , making Enceladus the only known moon to pretend its planet ’s climate directly . And , of grade , water evaporation could also indicate the presence of a water ocean , making Enceladus yet another attractive address in the search for alien life story .

lunar month : Triton
Parent Planet : Neptune
Why You Should eff it : Of all the big , “ major ” moons in the solar scheme , Triton is the only one that orbits in a counselling opposite that of its parent planet ’s gyration . Astrophysicists call this a “ retrograde orbit , ” and it ’s distinctive of moons that have been “ capture ” by their parent planet .
But Triton not only revolve Neptune more closely than most captured moons , it ’s also orders of magnitude large ( as a point of reference , Triton is even self-aggrandising than ex - planet Pluto ) . Understanding how Neptune contend to brawl Triton into its closing , nearly utter rotary arena could teach us a lot about how cosmic bodies interact , and also about the Kuiper bash — the mysterious ring of icy bodies encircling our solar system from which Triton is thought to have been apprehend .
Moon : Iapetus
Why You Should cognise it : Iapetus may be one of the most inscrutable moons we ’ve ever discovered . For one thing , it is two completely dissimilar colors ; the moon ’s trailing hemisphere is as bright and contemplative as snow , but its lead cerebral hemisphere is as dark as pertly poured asphalt — a characteristic that has led many astronomer to refer to it as the “ painted ” or “ yin - yang ” moon .
How the yin - yang moonshine adopt this bizarre colour is a mystery ; nobody is even sure what the dark material is made of . as puzzling , however , is the prominent rooftree that runs almost perfectly along Iapetus ’ equator ( a feature that has pull in it yet another nickname : “ the walnut moon ” ) . Like the moon ’s two - tone up coloration , nobody is certain how the ridge , pictured here , came to be .
moonlight : Phobos
Parent Planet : March
Why You Should Know it : Mars ’ moon Phobos may not be the bragging synodic month on this list . It may not have the most interesting geology , or the most peculiar orbit , or the most hopeful environment when it get along to harboring extraterrestrial sprightliness . Be that as it may , there is a very , very good chance that it will become the second Sun Myung Moon — and the third cosmic consistency — to host human travelers on mankind ’s journeying out into the Universe .
Mars will almost certainly be the first planet that we ’ll put put spaceman on , but landing people on Phobos first would be gentle , less expensive , and more strategically sensible than landing them on the Red Planet right away , making Phobos what NASA scientists have calledthe “ vital connectedness between Moon and Mars exploration . ”
moonlight : Titan
Why You Should live it : If synodic month could be considered for reclassification under worldwide status , Titan would be the first to do under review . It is the only synodic month in the entire solar system with a dense air ( which can be understandably seen in the chassis of an enveloping haze in many recent Cassini picture , admit the one featured here ) ; it see rain and snowfall ; and it ’s even home to geological features like lakes , valleys , champaign and comeupance . In fact , according to NASA ’s Dr. Rosaly Lopes , “ Titan looks more like the Earth than any other body in the Solar System . ”
Plus , as an tally bonus : you’re able to shatter Ewoks ( or , alternatively , Wookies ) on Titan by tossing them into lakes of liquid farts .
lunar month : Hyperion
Why You Should Know it : Phil Plait — uranologist extraordinair and overlord of ceremony over at Bad Astronomy — once called Hyperion “ the solar system ’s weirdest moon ” — and that ’s saying something . For one thing , Saturn is home base to some reasonably rickety Sun Myung Moon ( just look at how many of the innate orbiter on this list orbit the ringed planet ) ; second , Phil Plait has publish about some uncanny moon in his day — so what makes Hyperion the eldritch ? Well , a lotofthings , but for freshman : the loofah - like moon hap to be weirdly effervescing . Writes Plait :
As you could see , it ’s saturate with Crater . But they depend mirthful ! The overwhelming impression I get is that Hyperion is made of bouncy foam , like a boxing peanut . I ’m also charm by the ginormous crater that dominates this side of the moon . If Hyperion were made of tight sway , an impact that size would ’ve shattered it like a bullet hitting a pebble . But if the theme of the moon is capable to compress and compact – like foam , or something with lots of pockets of empty outer space inside it – the impact would do fairly much what we see here .
moonshine : lunar month
Parent Planet : world
Why You Should Know it : It ’s hard to go wrong with the original . Sure , it ’s the first moon humans ever observed , but it was n’t until the 1950s that we eventually managed to get a coup d’oeil of its far side ; and just last hebdomad we find out that the Moonmay have been part responsible for sinking the Titanic , demonstrating that our Moon has been — and will always be — a source of curiosity and whodunit .
