(100% Correct Answers)
why do we have to enlist amateurs to measure an occupation? Answer: the
occultation time depends on the position of the observer in the path of the
shadow
in what direction is the storm rotating CW or CCW? Answer: CCW as can be
inferred from the wake of the storm. this was confirmed by the space probe
voyager 1 that took a time-lapse of the storm.
is it south or north of the equator? Answer: south of the equator
what is the hedgehog theorem? and how does that explain the storm we have?
Answer: if you have a wind on a spherical surface, there must be a vortex
somewhere. also think of this as a "no-comb" theorem.
how was it possible to reach Saturn in only 7 years? Answer: the slingshot effect
was used to take advantage of the rotation of Venus, earth and Jupiter.
what kind of power did it use? solar panels? why? Answer: nuclear. the sun
radiation is too weak for solar panels at Saturn's distance.
what feature of Saturn is called after Cassini Answer: the large gap in the rings.
mercury Answer: is the fastest roman god.
only has an exosphere.
liquid/molten interior of metal.
1/3 the size of earth.
