Europa
Enceladus
Mars
Titan
Triton
100
This is an ice-raft area resembling Earth's polar regions.
What is Conamara Chaos?
100
This is the reason for Enceladus' unusually low surface temperature?
What is high albedo?
100
This polar ice cap has a larger surface area than the other one.
What is the North Polar Cap?
100
This is Titan's largest lake, discovered by Cassini.
What is Kraken Mare
100
This is what will ultimately cause Triton's destruction when it is pulled into Neptune's gravity.
What is the Roche Limit?
200
This is the relationship between Io, Europa, and Ganymede regarding their orbit, and contributes to Europa's heat source.
What is LaPlace resonance?
200
This is the primary component of Enceladus' atmosphere, possibly coming from the jets.
What is water vapor?
200
This is the point in Mars' orbit when the northern hemisphere is experiencing summer.
What is aphelion?
200
These are the only two missions to give us information about Titan.
What are Voyager and Cassini
200
This is what Triton's geysers are ejecting.
What is nitrogen gas and dust?
300
This is the more active of Europa's macula, as identified by its smaller and depressed features.
What is Thera Macula?
300
This is how the temperature of the tiger stripes compares to the rest of Enceladus.
What is 180K compared to 75K.
300
This time period in Martian history is associated with massive outflow channels.
What is Hesperian?
300
This middle member of the three carbon family was finally discovered on Titan.
What is propylene.
300
This is the region where most cryovolcanism and geysers exist on Triton.
What is the south polar region?
400
This is the instrument that discovered jets on Europa in December 2013.
What is Hubble Telescope?
400
This composition of the particles coming from Enceladus plumes lead to the suggestion of a subsurface ocean.
What is salt-rich?
400
This is what Recurring Slope Linea are believed to be.
What is subsurface briny water?
400
This is the best wavelength for penetrating Titan's thick nitrogen atmosphere.
What are radio waves/radar?
400
These two clues indicate Triton might be a captured KBO.
What are retrograde orbit, and composition similar to Pluto.
500
This can be formed by relative motion of ice plates, water welling up from underneath and freezing.
What are ridges?
500
This is how deep the snow cover from the plumes is.
What is 100 meters?
500
This is what Curiosity discovered in Yellowknife Bay suggesting a previous lakebed there.
What are clay-like minerals?
500
This is what led scientists to suspect a subsurface ocean on Titan.
What are low frequency radio waves from the Huygens probe?
500
This is the most likely theory of how Triton was "captured"
What is Triton was in a binary system disrupted by Neptune, Neptune captured Triton and tossed the other binary object.
