directly overhead at noon? - answer -Never
Imagine you live on the equator. Use the 24 hour clock (for example, 00:00 is
midnight, 05:00 is 5am, 12:00 is 12 noon, 21:00 is 9pm, 24:00 is midnight etc). To
the nearest hour, what time does the full moon rise where you live? - answer -

Imagine you live on the equator. Use the 24 hour clock (for example, 00:00 is

, The year is 2348. Climate change reduced Earth to an inhospitable wasteland. We
are attempting to terraform exoplanet 9876b in an effort to save homo sapiens from
going extinct. Our spacecraft was forced to make an emergency landing here, and
we know very little about exoplanet 9876b. It is your job to find out the size of this
planet.
You realize that, like Earth, this planet has a star near its North Celestial Pole. You
call this star New Polaris. You radio with another human that is 387km north of
your location. They tell you that New Polaris is 41.5 degrees above the horizon at
their location. At your location, it is 40.4 degrees above the horizon. What is the
radius of exoplanet 9876b, to the nearest thousand kilometers? - answer -20000,
2E4, 2.0E4, 20,000
A light-year is a measurement of _. - answer -distance
The majority of mass in the universe is made up of what? - answer -dark matter
What is your universe address? - answer -Earth, Solar System, Milky Way, Local
Group, Virgo Supercluster
The cosmological principle states that: - answer -The universe looks the same in
all directions as long as you look on large enough scales
You are an ancient mariner who has become lost in the ocean. You know you are
in the northern hemisphere thanks to familiar constellations. There is a very long
island nearby, so you know your longitude is 77°14'30" W. But because the island
is so long, you do not know your latitude. You look up and see Polaris is 33
degrees away from the zenith in your location. To the nearest degree, what is your
latitude? - answer -57
The earth has seasons because - answer -The earth's equatorial plane is tilted
relative to the plane of the solar system
We observe the same phase of the moon on a given night anywhere from earth -
answer -true
, An observer watching the moon at the equator will see the phase of the moon
change during the night - answer -false
You can observe a full moon on the western horizon at sunset. - answer -False
A star is 16 light-years away from earth. What is its observed parallax, in arc
seconds? - answer -0.2
I take a photograph of Jupiter every night in the sky at the exact same time. When
it is in prograde motion, then from night to night, it will appear to be moving: -
answer -Eastward relative to the stars
When the planet is moving from point A to point B, you will see it in retrograde.
(look at homework) - answer -true
What did Copernicus propose? - answer -Heliocentric model
**Know what the conjunction planetary configuration looks like** - answer -Sun
in center, Earth on one side, Planet on the other of the sun; all in a straight line
**Know what the western quadrature planetary configuration looks like** -
answer -Sun in center, Earth in front of sun, planet makes 90 degree w earth as the
corner
**Know what the superior conjunction planetary configuration looks like** -
answer -Sun then planet then Earth in straight line
The synodic period is: - answer -1. the time it takes for the same Sun-Earth-Planet
configuration to be reached again, eg from opposition to opposition.
2. The time it takes for the planet to be in the same position in the sky again as
seen from the Earth.
There is a glitch in the matrix. A new planet has appeared in the solar system in
between Mars and Jupiter. It appears in the same place in the sky every 560 days.
