Quiz
{Yes or No, With a diameter only slightly more than 300 miles, Enceladus just doesn’t have the bulk needed for its interior to stay warm enough to maintain liquid water underground. + Yes - No
 * type=""}

{Complete the text: Match up the blue object with the possibilities below: Sun - H Mercury - I Venus - J Earth - K Meteorite on Mars - L Pallas - M Comet Holmes - N Europa - O Io - P Saturn - Q Enceladus - R Tethys - S Titan - T Neptune - U Abell 370 - V SN 1987A - W Crab Nebula - X { T (i) }. { H (i) }. { N (i) }. { M (i) }. { S (i) }. { X (i) }. { O (i) }. { J (i) }. { V (i) }. { K (i) }. { R (i) }. { W (i) }. { Q (i) }. { L (i) }. { U (i) }. { I (i) }. { P (i) }.
 * type="{}"}

{Yes or No, Enceladus is not completely spherical, so as it moves in its orbit, the pull of Saturn's gravity generates a net torque that forces the moon to wobble. + Yes - No
 * type=""}

{True or False, A plume of water ice particles emanating from Enceladus is reaching altitudes as high as 400 km above the surface. + TRUE - FALSE
 * type=""}

{Yes or No, Enceladus' orbit is kept oval-shaped, maintaining the tidal stress, because of the gravitational tug from a neighboring larger moon Dione. Dione is farther away from Saturn than Enceladus, so it takes longer to complete its orbit. For every orbit Dione completes, Enceladus finishes two orbits, producing a regular alignment that pulls Enceladus' orbit into an oval shape. + Yes - No
 * type=""}

{Complete the text: Match up the letter of the spherical object with each of the possibilities below: Sun - A Mercury - B Venus - C Earth - D Moon - E Mars - F Ceres - G Jupiter - H Callisto - I Europa - J Ganymede - K Io - L Enceladus - M Titan - N Uranus - O Titania - P Neptune - Q Triton - R Pluto - S { M (i) }. { R (i) }. { L (i) }. { H (i) }. { G (i) }. { J (i) }. { P (i) }. { S (i) }. { D (i) }. { O (i) }. { E (i) }. { I (i) }. { K (i) }. { Q (i) }. { N (i) }. { A (i) }. { F (i) }. { C (i) }. { B (i) }.
 * type="{}"}

{Yes or No, Scientists estimate from the Cassini data that the south polar heating is equivalent to a continuous release of about 13 billion watts of energy. + Yes - No
 * type=""}

{Which of the following are associated with hydrocarbons? + liquid lakes on Titan + petroleum deposits on Earth + methane in the atmosphere of Uranus - Enceladus + atmosphere of Neptune - an H II region
 * type="[]"}

{Yes or No, To explain this mysterious warmth, some scientists invoke radiation coupled with tidal heating. + Yes - No
 * type=""}

{A fine spray of small, icy particles detected in green light is emanating from what surrounding, warm, geologically unique province of Enceladus? { the south pole|south pole (i) }
 * type="{}"}

Hypotheses

 * 1) Enceladus has a frozen surface because it traveled with Saturn from its original or earlier position.
