After the Voyager Probe has explored the
planets of our solar system, astronomers
have come to the conclusion that Saturn’s
rings are made out of what?
(3 possible points)
Ice, dust, and rock
Which planet was first discovered to have a
rotational period longer then its revolutionary
period and is thought to be from an Impact.
Venus
Which moon is most exciting due to its nitrogen
rich atmosphere, similar to a young Earth?
Titan
Why might Venus be of interest for
humans to study?
A. The atmosphere in the same in terms of
composition and temperature.
B. It’s similar to Earth in terms of size and
composition.
C. We have found remnants of microbacterial
life on Venus.
Ans. B
What is the difference between orbit and
revolution?
Orbit is the path the planets take…
Period of Revolution is the time it takes to
go around the sun.
Which planet has virtually no atmosphere?
Mercury
a. Dwarf planet with 2 moons
b. Dwarf planet that is basically an
extremely large, round asteroid.
a. Haumea
b. Ceres
What best justifies scientists’ high levels of
interest in Jupiter’s moon Io?
A. There could be microscopic life in the
oceans under its icy surface.
B. Its atmosphere is similar to that of
Earth with high amounts of nitrogen
C. It is covered in active volcanoes, which
could be from plate tectonics, which
could mean future H2O
Ans. C
What is thought to have happened
to Uranus to give it a 98 degree
tilt?
• It is thought to have had a collision with
another planet
Give an explanation as to why Neptune is
occasionally further away from the sun then
Pluto.(2 pts.)
Pluto’s orbit is more eccentric and tilted
Why does Uranus have seasons
that last so long?
**over 20 years**
-Since Uranus has a 98° tilt, the sun focuses on
one side for a long time.
If Venus were to suddenly cool, why would
the development of advanced seasons be
impossible?
Venus’s tilt is 2.6 degrees. The sunlight
would hit directly on the equator all
year.
Although intelligent life may not exist in our
solar system, microscopic ocean life may
exist in the oceans on:
Europa
What is synchronous rotation and
revolution?
• When something rotates and revolved at the
same pace. One side will always face what its
revolving around.
Besides our moon, which is the only
other moon to experience synchronous
rotation and revolution?
Neptune's moon-Triton
Final Jeopardy:
How many points
do you want to
wager?
Two factors that influence the force of gravity
of an object are mass and distance. Knowing
this, justify as to how Venus and Uranus have
the same gravitation attraction (.91 of Earth).
Venus- Higher mass and lower volume.
Uranus- Lower mass and higher volume.
